Spring-Summer 2010 Mat Plus Review 13-14 ENDGAMES 2009 by Mirko Miljanić (Serbia) First of all, I would like to express my thanks to the editorial team of Mat Plus for their confidence in me, especially because this is my maiden judging. I must stress that my job was made much easier because as far as the soundness and originality of entries is concerned I could rely on the knowledge and work of the column editor Iuri Akobia, as well as to the expertise of the magazine readers. In four issues of 2009, (Mat Plus 33-34, 35 and 36) there were 35 original endgames by 20 authors. I find that the overall level of the tourney was very satisfactory both in terms of quantity and quality. I decided to reward 17 works in the following order: Darko Hlebec Richard Becker |||||||| £p£¤£¤£¤ |||||||| ¤«¤«¤£¤£ |||||||| £¤©¤»¤»º |||||||| ¤£¤£¤£º£ |||||||| »¤£¤¹¤¹¤ |||||||| ¤£¤£1£¤© |||||||| £¤£¤£¤£¤ |||||||| ¤£¤£3Yn£ |||||||| £¤G¤£¤£¤ |||||||| ¼£¤£¤£¤£ |||||||| £¤£¤£¤£¤ |||||||| ¼£¤£¤0¤£ |||||||| £¤£¤£¤£¤ |||||||| º£X£¤»¼» |||||||| ¹¼£¤£¤£º |||||||| ¤Y¤£¤£3£ 1.pr Mat Plus 2009 = 2.pr Mat Plus 2009 8+8 + 6+8 1.Qc5+! /i Kxh2 /ii 2.Rxf3! /iii Rc1 3.Rf2+ g2 4.Qe5+ Kh1 5.Rxb2 Rf1+/iv [6.Kg4 g1Q+ 7.Kxh3 Rf3+ 8.Kh4 a4 /v 9.Rd2! /vi a6 /vii 10.Rb2! a5 11.Re2!

A dynamic and sharp battle gradually builds intensity with a sacrifice of the black knight (4…Sd8!) and a counter-sacrifice of its white counterpart (5.Se5!) and gains in aesthetical quality, culminating in paradoxical and humorous minor promotions which cannot be realized: 8.e5!! but not 8.h8=Q? a1=B! and 8…a1=Q! but not 8…a1=B? 9.h8=S!!. This allows White to carry out his stalemate intention. 3rd Prize: 1440 – Borislav Ilinčić (Serbia). 1.Bf2+ Rxf2 2.Sxf2 Bf4+ 3.Kxf4 Kxf2 4.h7 Sd8 5.Se5 /i Already on first glance this endgame attracts the Sxe5 6.Kxe5 /ii a3 7.Kf6 a2 8.e5 /iii a1Q /iv 9.h8Q Qxe5+ solver’s attention.

A and both queens remain on the board, while the ground-stone of this endgame is the interesting main role is usurped by the white king which uses mutual zugzwang which arises after 8.Kh4 (not a logical maneuver to un-ambush the dangerous counting the pawns on the a-file). On top of it is black bishop.

The precise play of White based on the wrong-cornered black bishop is probably important for endings theory thanks to the genuine “endgame move” 4.Rb1!, while the phenomenon that the white rook visits all four corners looks fairly incidental. 1.Kf2 /i Bb3 2.Re7 /ii Bd6 3.Re1! with two main thematic lines: A) 3…Ba4 4.Rb1+ /iii Kc7 5.Rh1! /iv (wR on the corner 1) Be8 6.Ra1!

The cult theme Lačný – Shedey – Tura cycle after two King’s defences is shown for the first time and the author has found an attractive matrix for its realization. On the one hand both the try and key are “taking” the flight e4, on the other hand they are “giving” the distant flights b5 and d7, which is acceptable when the black King is moving. The secondary taken squares b4 and e7 are related with another motivation for White’s first moves. The innovative, technical and artistic aspects make this composition a masterpiece. *1...

An interesting idea by the pair of authors, which needs deeper research of all contexts between variations of the set play, thematic threats and the real play. Its content is the change of continuation in two 2nd, partially also 3rd moves, combined with the change of two intervariation moves. A proper addition is also the reversal of moves Sb3 and Sc7 in the set play. Only the multiple appearance of the move Sb3 is disturbing.

The Djurašević + Urania themes shown in a massive matrix with lots of white Pawns (some of which act just as hurdles for the white Queen). The Djurašević theme of the Gockel type combined with the Urania theme has been built several times before in better construction (see D. Stojnić, 3. pl Liga Problemista TT 2006.) The author has already shown a similar theme in 2007 (2nd Pr Mat Plus 2007, No. 572) with much better economy. In spite of this, the realization of this difficult theme deserves to be awarded, as the motivation is more complicated and the scheme is different. 1.Qxd7! ~ 2.Se7+ Ke5 3.f4# 1...

The ideal form of the Djurašević theme with a potential en passant capture is achieved in a very interesting way.

A set play in one variation is connected with the reciprocally changed black moves (c5 and c6) and a change of the W2 for a W1 move in the real solution. The play is coloured by geometrically interesting moves of the Queen and opening of the line d2–h6 by the key. Lively and smart content of the best miniature. 13+11 3rd Honourable Mention: No. 1207 – Sergei Tkachenko (Ukraine). Four white pieces arrive on the same square on the 2nd move. A geometrical theme that occurs on the squares e4 and d4 in 2nd – 3rd moves that seems to be original. Not just difficult, but lovely. 1.c8=S! ~ 2.dxc4+ Kxc5 3.d4# 1... cxd3 2.c4+ Kxc5 3.Bd4# 1...

Here is the list of entries: Mat Plus 33-34: originals 1283-1309, Mat Plus 35: originals 1383-1401, Mat Plus 36: originals 1478-1499 and one on p. 96, Mat Plus Review 9-10: no. 43, p. 27, Mat Plus Review 12: nos. 9, 10, p. 166, no. 22, p. 167, nos. 31, 34, p. 168, nos. 38, 40, p. 169, nos. 7, 8, p. 171, nos. 11, 12, p. 172, nos. 5-7, p. 209, nos. 2022, p. 211, nos. 42, 43, 43a, 43b, 44, p. 215, nos. 49, 50, 52, 54, p. 216, nos. 60, 61, p. 217, no. 71, p. 219, no. 2, p. 220, nos. 3, 7, p. 221, nos. 8b, 8d, 9, p. 222, nos. 13, 14, 16b, p. 223, no. 20, p. 224, no. 22, p. 225, nos. 31, 32, p. 226. This is a considerable number of entries and maybe the relatively small number of awarded ones is surprising, especially as I consider the overall quality to be good (on the same level as in other well known and established magazines). But even in their issues I quite often see problems with only a basic use of the chosen fairy elements. I would like to expect more problems where composers prove that they already know these specific fairy properties and use them in an appropriate way. I was a little bit disappointed by the quality of the helpmates – a lot of them realized only basic ideas of single fairy conditions or pieces and thus they were quite good as advertisements for such fairies or as simple examples in an anthology, but nothing more. This demonstrates the fact that it is easier to compose a simple helpmate than a simple direct mate problem (as in the orthodox field). I believe (and think) that the possibilities of fairy chess give more space for development of ideas presented in orthodox helpmates, and I hope that composers will strive more for such achievements. tradition. Finding a new pattern or new possibility can take a lot of time, but I cannot admire only the length. In the award there is one record, in which I appreciated the economy of force (and time! – it is the shortest one) and the repeated manoeuvre. A similar case appears in problems which have quite often been published in recent years: combinations of maximummer (or minimummer) with some other fairy condition (mostly KöKo and/or PlatzWechselCirce) showing some echo mates. But I prefer much shorter solutions (when the same content can be achieved): otherwise playing through the author’s intention is usually boring and shorter problems are for me as a solver more acceptable. (And in this judgement it is not important whether such problems were created by computer or human brain.) The article about helpselfstalemates illustrated the disadvantage of this kind of problem in comparison to helpselfmates – there are only very limited possibilities on the last move (this is also true when comparing direct mates and stalemates). The end of the solutions (and partly their content too) can in helpselfmates be much more varied and for this reason I don’t expect that helpselfstalemates will be more widely composed. “Feather’s excelsiors” using two neutral pawns promoting in each case on the other side of the board: again, already its basic requirement – a lot of pawn moves – means that a great part of the solution is boring, consisting only in steps by the thematic pawns and usually only the last two moves are interesting. For me the most interesting article was the one showing two different antibattery mates in a serieshelpmate. On the other hand, the article mostly used the form of setplay and solution, which gives only limited space for the used fairy pieces and “intensity” of the solution – of course the setplay must be destroyed (by capture or non-reversible move) and then some other mating net has to be built. I believe that in this field multisolution form offers more possibilities. A significant number of the judged problems were published in theoretical articles. In my opinion such problems are disadvantaged in comparison to the others, because they are usually too similar (as was the case in the current tourney and articles). In general: I am not interested in length records. Sure, they are (mostly) well developed intellectual achievements, especially in the But time to stop talking, now we come to the fields where records already have some awarded problems.

In making the award I took into consideration the correction of the endgame No.1248 by Richard Becker which was published on the Mat Plus site. I thought that it should have been included in the 2009 tourney. Mihai Neghina, the author of endgame No.1247, stated in his comment published in Mat Plus 36 that the black pawn should be on a6 instead of a7. I spent a long time in the analysis of this endgame, especially because I felt that the “crowd” of pawns on the queen’s wing could be reduced to only two (one white and one black). Although I didn’t succeed in finding the desired position I was (and still am) convinced that it exists, and therefore I commented that this group of pawns was not quite in proportion to the content of the endgame and for that reason, as well as because of the static white rook, I ranked it lower than this attractive and interesting idea would otherwise have deserved. I am thankful for all the remarks that contributed to the explanation of these omissions. Some of these remarks were related to the soundness of the endgame awarded 1st Prize. However, the claim that after 10…Qd6 Black wins seems to be false since analysis has shown that White draws with 11.Kh5! (stronger than 11.Kh7) 11… Qd5 12.Qf6+ Kg3 13.Qc3 Kf2 14.Qf6+ and continuous check or for Black an unfavourable exchange of queens which leads to a drawn position. 193 Mirko Miljanić July 2011 Mat Plus 41 TWOMOVERS 2009 Judge: Dragan Stojnić (Serbia) Officially 30 problems took part in the 2009 tourney, published under numbers 11931201, 1324-1330 and 1412-1426. One original was withdrawn because the authors found a significant improvement and decided to publish it elsewhere. In addition there were 6 originals by the editor in two articles in Mat Plus Review (5 in “Ideal Ruchlis” and one dedication to the judge), but the author insisted that these would not take part in the tourney. Nevertheless, I decided to reward the best two of these with special distinctions. Also, there was one original of mine (in the article about the Đurašević theme) which, of course, could not compete in the tourney, as well as two originals published (in an article about en passant keys) which, being retro problems, belong to the Retro/Math section. As the criteria for publication of originals was not so severe, about ten problems were immediately excluded because of poor quality. Judging by the names of the authors the tourney promised much better compositions, but obviously some authors have a habit also to publish the side-products of their work. Anyway, thanks to the quality of about a dozen compositions which were worthy of rewarding it can be said that the quality of the tourney was satisfactory and that the top ranked works do not fall behind the prizes from other eminent tourneys. The trifles (small details) took an important part in making the final ranking, which is as follows: Marjan KovaÜceviæc 1.pr Mat Plus 2009 Aaron Hirschenson 2.pr Mat Plus 2009 Pavel Murashev 3.pr Mat Plus 2009 £¤£p£¤©¤ |||||||| ¤£¤£¤»¤G |||||||| £¤£¬£¤m¤ |||||||| ¤£¤£¤£3£ |||||||| £Z£¤£¤£¤ |||||||| ¤£¤£º£º£ |||||||| £¤£¤£¤©¤ |||||||| ¤£¤o1WX£ |||||||| £¤o¤£¤£¤ |||||||| ¤£¼£¤£¤Y |||||||| £¤G¤£¤m¤ |||||||| ¤£1»3»¤£ |||||||| »¤¹¼£ª«X |||||||| Z£¤£º£ª£ |||||||| £¤£¤«º£n |||||||| ¤£¤£X£¤£ |||||||| £¤0¤©¤£¤ |||||||| ¤m¤£¤»¤« |||||||| G¤£n¹ª»¼ |||||||| ¤£¼£¤2p£ |||||||| £¤£¤W¤£º |||||||| ¤£¤»¤o¤¹ |||||||| £¤£¤¹¤£¤ |||||||| ¤£Z£¤£¤£ |||||||| #2Ä #2* #2ÄÄÄÄ 9+6 11+11 11+10 1st Prize: No.1417 – Marjan Kovačević (Serbia). A “festival” of originally presented Dombrovskis and Vladimirov paradoxes between try and actual play. The content shows the Ideal pseudo le Grand combined with a specific form of anti-reversal after the thematic move by the black king. Among other notable details the most striking is a transformation of the character of defences: a bi-Valve of the black king in the try becomes a clearance for the white battery after the key, while the exposure to capture fxg6 becomes a selfblock. Everything is done very economically, with only 15 pieces on the board, and this, together with high originality, was the decisive factor for ranking this problem at the top spot. 1.Sf4?(A) ~ 2.Qh4#(B), 1...

Bxg4 2.Qh6#). 2nd Prize: No.1432 – Aaron Hirschenson (Israel). A reciprocal change mechanism based on a brilliantly utilized opening and closing of lines and indirect battery creation. What is particularly intriguing in this problem is the fact that both black defences activate masked lines, and this gives a deeper sense to the play, just as the always welcome analogy between variations does. The consequence of the thematic defences (Sc3/Sf6) in the set play is once closing of the black and once opening of the white line. The excellent key activates the white halfbattery and at the same time sacrifices the piece on the flight square. Now one opening of the white masked line (Sf6) allows a double check mate and another (Sc3) unguards d4. This transformation is simply fascinating. The additional play reveals the role of the seemingly unemployed Bg6. Finally, the author deserves all credit for his persistence in searching for new mechanisms for reciprocal change of mates which, considering how much this theme has been exploited in the past, becomes more and more difficult with every new day. *1...

Rd7,Be6,Bb7 2.Qe6#. 3rd Prize: No.1421 – Pavel Murashev (Russia). A lot of content featuring change of mates in four tries and in the solution. Besides the Zagoruiko 3+2+3 we can recognize one Dombrovskis paradox and one Dombrovskis variation, as well as transfer of mates. The flight giving key is the best possible choice, which gives the composition one extra quality. Also, the selfblock on the flight is followed by the mate Qd3, the move which is the introduction to one of the tries. However, it seems to me that there is no real unity between the three main phases and that prevented higher placement of this problem. 1.Qxd3?(X) ~ 2.Qd5#, 1... Bf4 2.Re5#(A), 1...

Bxh4!). 1st Honorable Mention: No. 1425 – Givi Mosiashvili (Georgia). A very complex 5phase scenario (the sat play was omitted in the originally published solution in the magazine), the understanding of which requires deeper analysis. If only changed mates are counted there is a partial Zagoruiko 2+2+1/1. The try 1.Bc4? together with the solution completes a pseudo-Salazar theme. Add to it the set play and we get a paradoxical form of the Banny theme (where the variations Sgxe7/Sdxe7 serve instead of the native Banny theme characteristic refutations). If we associate all of this with the try 1.Qb4? we can recognize the Hannelius theme, also in a paradoxical form (threatsmates Sc7/f8S). However, there is an unpleasant refutation of the important try 1.Bc4? by a random move of the black bishop, and this is to my understanding a serious flaw (though some “schools” tolerate this). *1...

A nicely conceived variation of the theme for the “Subotica 2009” Internet tourney. That tourney required corrective Dombro-paradox, here the author shows the same paradox without 7 July 2011 Mat Plus 41 correction. The mechanism is supplemented with additional changes after the defences Sd4 and Qd3. The set play together with the try 1.Sc3? creates a native Dombrovskis, with a fine selfblock on d3 in additional play. The key 1.Sf2! closes the wRf1 line, but puts an additional guard on d3 transforming the main thematic defence gxf3 into a changed selfblock in relation to the set play. This results in a transfer of the mate Qg5. The additional try 1.Kg2? extends the content to a third phase, changing the motif of the thematic defence into a check.

A solid conception with change of two mates in Dombrovskis paradox form with dual avoidance after selfblocks in the set play and with a flight giving key. The additional change on the same square (c6) adds much to the value of the problem. The separation of threats by the half-defences Be2 and Se2 after the key, in not too strict words, completes the Ruchlis theme. *1... Bxe4(a) 2. Qa1#(A) (2. Sf3#?), 1... Sxe4(b) 2. Sf3#(B) (2.

An interesting interpretation of the 8th WCCT theme, where three thematic 8 Mat Plus 41 July 2011 and one additional non-thematic move are cyclically used in two separate systems of double threats. The weakest point in this complex is the try 1.Re2? with a probably unavoidable checking refutation. Everything is here motivated by control of the squares f6, e4, f4 and g4. The lack of changed play prevented higher placement of this problem. *1... Sf3 2.Sg4#(D), 1... Rg5+ 2.Rxg5#; 1.Rg4? ~ 2.Qxe4,Bd4#(A,B), 1... Sf3!; 1.Qh6? ~ 2.Bd4,Rd5#(B,C), 1...

An unusual complex which combines the Odessa theme with the variation-form of cyclic pseudo le Grand with double threats (A-B, BC-XY, XY-ACB). The best part of the problem are interferences of the black queen and openings of the white rook line by the black Pe7. The author’s choice of 1.Rxe7! for the key is justified by the fact that only then does the white Ba1 take a role. Another judge might have ranked this problem higher, but for my taste without changed play the whole conception looks somehow inferior. 1.Rf8? ~ 2.Sxe7#(A), 1...

The stubborn repetition of the same refutation must be criticized. However, a nicely executed harmonious change of mates between the try 1.Sf4? and the solution qualifies this twomover for a distinction. 1.Qh5? ~ 2.Rxd5#, 1... Se3(a) 2.fxe3#(A), 1...

Although I am not very fond of problems where in thematic phases a flight is taken from the black king, this double “give and take” system is worth mentioning because of a nicely incorporated change of mates to 3 thematic defences distributed between two tries and the actual play.

An ingenious presentation of Ideal Ruchlis, one of the best I’ve ever seen, originally conceived around the transferred mates after the corrective moves. The change and transfer are based on various elements: changed guard on four squares (d5, e3, e5 and 9 July 2011 Mat Plus 41 f5), and opening and closing of two black lines. The same mechanism is shown in No.291 in the same article, but there one white bishop was idle after the key. Here all white pieces are utilized in the solution. *1... Sd~,Sf5 2.Rf4,Qc6#, 1...

Judging this Noah’s Ark-like group of problems (21 types with 13 different fairy conditions) was a difficult task, as it is hard to compare what cannot be compared. This is why my award was based on other criteria such as: the pleasure taken while solving, the shown themes, the achieved tasks, the new ideas, the depth of the problems, difficulty).

The wS trip (free in the diagram position) was also a potential cookenabler. The author once more succeeds in obtaining an almost airy position with 48 fixed retro-moves, which is a considerable achievement. A very attractive problem whose solution can be discovered through a very accessible logical deduction. 2nd Prize: No.1506 – Dragan Lj. Petrovic (Serbia). The position can be untied only by uncapturing h4xPg5(Pg7), on the condition that a black Pawn is brought back to g7. In this type of problem, this is usually achieved by freeing a white unit which moves from its original square to the squares where the bPs are captured, which allows shifting the bPc7 towards the h-file. The initial position seems quite blocked and first retrostalemate must be avoided. Retro: 1... Sg1xSh3(Sb1) 2.Ra1-d1 a5xRb4(Ra1) 3.Sd1-f2 a6-a5 4.Bf2-e1 b7xBa6 (only missing unit) 5.Qe1-f1 Circe Sf1xPg3(Pg2) 6.Sg3-f1+ g2-g3 7.Sg3-f1+ 7.Sb2-d1 How many moves by Sd4 to unlock?

The foreplan is over and now the retrocapture of wQ by the bPs must be optimized, so that there are enough black tempi to allow the wQ returning to d1 through h3-g2-f2-f1d1. The thus given tempi are not enough and the wB must be used in order to obtain two additional tempi. One more subtlety: for the white-squared Bishop to uncapture twice on white squares, the black c-pawn must also be shifted to the c-file. The black c-pawn can then be shifted to the f-file, but then there is another problem, because it will be impossible to uncapture the bP on f6 because of the check to the black King. – The key of this problem is to uncapture the black f-pawn on f2, allowing it to resume its journey by g3xQf2(Qd1)- h4xPg3(Pg2) – h5 – h6 – g7xQh6(Qd1) (phew !) – And finally 160.h4xPg5(Pg7)!! – Detailed solution: see p.95 Mat Plus 36, Winter 2009. A new task because 159 Circe retro-moves are necessary in order to unlock the position by h4xPg5(Pg7). Admittedly the author’s length record is not beaten: 302 Circe retromoves in problem no.3323 feenschach 55, 07/1981, but his search for tasks showing original manoeuvres (allowed by this fairy condition) goes on with renewed vigour. I have found 14 such problems published in 2008-09 and 7 in 2010. The result is convincing, since it blends difficulty (the basic manoeuvres must be conceived), length (159 retro-moves), paradox (apparent impossibility to retro-move g7xQf6) and subtlety (foreplan, hidden key Sh3xPf2). This mammoth problem should find a place in the FIDE Album. To be compared with [A] which sets the mark still higher with 226 retro-moves before untying a similar position through h4xPg5(Pg7). The tempo manoeuvre of the pinned bS is identical and the wQ retro play is similar, with the help of a wR instead of wB. 15+16 4 Mat Plus 42 January 2012 3rd Prize: No.1323 – Klaus Wenda (Austria).

Millour (France). (Detailed solution in Mat Plus 35/2009, p.35) Retroanalysis does not intervene in the first part of the problem. Using the Imitator considerably limits the freedom of movement of both sides and allows achievement of the Babson Task. Indeed, the mate will be realised only by Rh6-f6(Id3-b3) on the condition that both squares b2 [blocking the Imitator southwards and preventing the defence KxRf6(Ib3b2)], and d7 (blocking the bK’s flight) are blocked. It is impossible to block d7 with a wQ/wR which would give check to the bK, or a wB (white-squared) or a wS that cannot reach d7 in 2 moves. These moves would not necessarily be possible because of the Imitator. Anyway, a wPd7 will be needed and will be obtained by unpromoting a white unit from d8. In order to maintain the Imitator on d3, the sides must take back homothetic moves, which leads to similar promotions and thus the Babson Task is achieved. However, you can’t stop there, because then the structure of the white Pawns implies 7 captures, among them the ‘a’ black Pawn which has been promoted. It would seem possible to uncapture a white piece for free during retroplay (wSd1, a1, b2, d2, wRa1 or wQd1 according to the situation, but not the wB captured at home), which would cook 5 January 2012 Mat Plus 42 the problem. But the count of the horizontal movements of the playing pieces leads in all cases to a negative total of -5: that would mean that the Imitator would have been off the board at the beginning of the game. Therefore the missing unit has not been captured on files ‘a’, ‘c’ or ‘d’, which forbids an uncapture during retroplay and ensures the uniqueness of each solution. An extraordinary feat by the author who shows the 2nd Babson Task in a retro problem (for the 1st see René J.

Therefore the wSc5 must get out, which is possible if a bS is uncaptured on c5. Then a bS must be brought back to b8, which is possible only with a subtle manoeuvre of uncapture of the bSh7 which cannot reach square b8 in a natural way. This manoeuvre becomes possible thanks to a white tempo that will be obtained by uncapturing wPa3. The retro-opposition wK-bS forces the latter to uncapture the wP twice!

We are accustomed to seeing the author employing a Queen for this type of manoeuvre. Here the use of the Circe Knight is very interesting. The double uncapture of the wP (mandatory because of the parity of S moves) is unexpected. The manoeuvre consisting of uncapturing on h7 in order to make the bS go through the lock is well conceived. Admittedly the wK is free to move, but the problem is well built and very difficult to solve. This problem really treads off the beaten track. 6 Mat Plus 42 January 2012 Itamar Faybish 3.hm Mat Plus 2009 £¤o¤2¤£Z |||||||| |||||||| ¤£¼»¼W¼» |||||||| £¤»¤£¤£¤ |||||||| ¤»¤£¤£¤£ |||||||| £¤£¤£¤£¤ |||||||| ¤¹¤£¤£¤£ |||||||| £º¹º¹¤¹º |||||||| ¤©nG1m¤W PG in 14.0 14+10 Kevin Begley Kostas Prentos 4.hm Mat Plus 2009 Y¬oJ2p«Z |||||||| ¼£¤£¤£º¹ |||||||| £º¹º¹º£¤ |||||||| ¤£¤£¤£¤£ |||||||| £¼£¤£¤£¤ |||||||| ¼£¤»¼£¼£ |||||||| £º»¤£¼£¤ |||||||| X©nG1mªW |||||||| PG 15.0 16+16 Circe Parrain Itamar Faybish 1.cm Mat Plus 2009 Y¬o¤2¤£Z |||||||| |||||||| ¼»¼»¤»¼» |||||||| £¤£¤£¤£¤ |||||||| ¤£¤£H£¤£ |||||||| £¤£¤¹¤£¤ |||||||| ¤£¤£J£¤£ |||||||| ¹¤¹¤£º¹º |||||||| ¤£¤£1m¤W 10+13 SPG? Irregular grid chess (gridlines between each pair of verticals; i.e., straight vertical moves are illegal) 3rd Honourable Mention: No.1404 – Itamar Faybish (Belgium). There has obviously been a promotion of the white f-pawn and it is very tempting to promote a wR in order to easily capture the bBf8. There are already 13 necessary white moves out of the 14 of the stipulation. The main difficulty resides in making the bK avoid the wR’s check on f8. The author’s idea is very convincingly achieved and the solver will be surprised to discover several unexpected themes, because everything is well hidden in the diagram position. 1.Sf3 Sc6 2.Sd4 Se5 3.Sc6 bxc6 4.f4 Ba6 5.fxe5 Qb8 6.e6 Qb3 7.axb3 0-0-0 8.exf7 Re8 9.fxg8=R Kd8 10.Rxh8 Bc8 11.Rxf8 a6 12.Rf7 Rh8 13.Ra5 Ke8 14.Rb5 axb5.

Indeed the Circe condition allows having Pawns reborn at will and multiplying en-passant captures, but in Parrain Circe this is much trickier to handle. The idea is unusual since for this en-passant task the authors reach 10 enpassant captures in only 15 moves. The record is noteworthy.

The logical deduction is very interesting. Here is a Proof Game that must be studied as an actual retro problem. In this vertical grid the Kings are not in check because the Queens cannot move forward vertically. The wPe4 can only be coming from e2 after two white-squared captures: this excludes the capture of Bf8 by this pawn, which has therefore captured the bSg8 and another black unit. But the bPe7 can only play on black squares and therefore has not been captured by the white e-pawn: bPe7 has been promoted. This last promotion implies 6 dark-squared captures, i.e. all white missing units. This black pawn has captured the white b- and d-pawns, one of them having captured bBf8. 7 January 2012 Mat Plus 42 [B] Itamar Faybish Phæenix 189-190, Dec. 2009 Y¤£¤2p«Z |||||||| ¼»¼£¤»¼» |||||||| £¤£¼£¤£¤ |||||||| ¤£¤£¤£¤£ |||||||| £¤£º£¤£¤ |||||||| ¤£º£¤£¤£ |||||||| ¹º£1£¤¹º |||||||| ¤£¤£¤£HW |||||||| SPG 16.5 ?

The fourfold Ceriani Frolkin QQSb leaves an aftertaste of unfinishedness because the AUW is narrowly missed and the check to the black King quickly unveils that a promoted black unit is necessary. Admittedly a check is better than an additional promoted unit in the diagram position, but the author has not been able to avoid these defects to achieve his idea. There are two roundtrips of white Pawns promoted into Queens (g2→g8=Q→Qg2 and e2→e8=Q→Qe2). Together with the wP sibling (e4) and the fourfold Ceriani-Frolkin, this problems deserves being awarded.

(~ 2.Qh5-f3 & #2) h5-h4 2.e4xBd5 Ke8-f8 3.e2-e4 and black loses castling rights so white mates in 2 with 1.Qxd5! The promoted unit in the diagram position is not pretty and Black’s retroplay serves only to prevent the mate in two moves prepared by White! The first move is subtle, because the threat is not obvious, but the rest of the retroanalysis is simple. However, the idea to restore the black 0-0 (by Black) and to break it again (by White) is original. APPENDIX 1312*. Henryk Grudzinski (Take & Make).
