see that the white king would be much better placed on e7. 37. Qc3 h6!! There is no fortress with the pawn on h7. 38. Kf5+ Kh7 39. Qc7+ Rg7 = Black reaches a well-known fortress discovered by Guretzky-Kornitz (1864).
White cannot break black's rook g-file defence.

"In my eyes, this study was the clear winner of the tourney. After the classical K vs R systematical movement (moves 2 to 9) one would expect the natural 10. Kc2 to follow in order to get the king closer to the black rook, but that move is just a logical try! The amazing 10.Ka2!! and a complex systematical movement is needed to before returning back to the main plan with the move 27.Kc2! By then, the black king is attracted to the 6th rank which makes possible the pin with 33.Rb6!"</i>

<i>The following presentation is by the author of the study.</i>
</p>
<p>
Strategic miniature with logical content and systematic king movements up and down the board. The question is how White must break the opposition 1. g3 Kd1. White needs to play Ka3 at the right moment, when Black cannot reply Kc3 due to the f4-f5 breakthrough: h8Q occurs with check!. But first, the king needs to go all the way up to b6!
<b>1. g3</b> Forced since Black threatened g4-g3.
<b>1... Kd1!</b> Black can rush to the kingside, too. After Kf2 or Kf3, White plays h4-h5 g6xh5 f4-f5, promoting the f-pawn with check. Black then draws against the queen [1] pushing both the g- and the h-pawn if the white king is on the seventh rank, the b-file or on c6; [2] with the doubled g-pawn after hxg3 with wKd6. With wKd5, like in the solution, White is winning. (e.g., 1... Ke2 2. Kc2 Kf3 3. h5 gxh5 4. f5 +-)
<b>2. Kb2 Kd2 3. Kb3</b>
Thematic try: White would like to play 3. Ka3? luring the black king to c3 so that f4-f5 works.
However, Black draws with Ke3 (or Ke1/Ke2) (3... Kc3? 4. f5! gxf5 5. h5 +- and White promotes with check) (3... Kd3? 4. Kb3 and Black must give up the opposition) 4. Kb4 Kf3 5. h5 gxh5 6. f5 Kxg3 e.g. 7. f6 h4 8. f7 Kh2 9. f8=Q g3 =
<b>3... Kd3 4. Kb4 Kd4 5. Kb5 Kd5 6. Kb6! Kd6!</b> Black keeps the opposition
(6... Ke4 Black tries to exploit the remote position of the white king. 7. Kc5! (Logical try: 7. Kc7? (or Kc6) Kf3 8. h5 gxh5 9. f5 h4/Kxg3 transposes 10. f6 Kxg3! Now the two pawns are strong enough for draw, e.g, 11. f7 Kh2 12. f8=Q g3 13. Qf4 h3 14. Kd6 Kh1 15. Qxg3 h2 =) 7... Kf3 8. h5! gxh5 9. f5 h4 10. f6 Kxg3 11. f7 Kh2 12. f8=Q g3 13. Qf4 h3 14. Kd4! +- and the king arrives in time.)

<b>7. Ka5!!</b>
</div>
<p>
Now the black king can't attack the g-pawn directly, and so White can afford to move the king to the a-file. Logical try: 7. Kb7?! Kd5! (If Black continues to mirror White's movements, the h-pawn queens with check: 7... Kd7? 8. Kb8 Kd8 9. Ka8 Kc8 10. f5! gxf5 11. h5 +-) 8. Kc7? (8. Kb6! Kd6 leads back to the position after move) 8... Ke4! 9. Kd6!? The white king is now too close to draw with g- and h-pawn like in main B, but the second defense plan works: 9... Kf3 10. h5 gxh5 11. f5 h4 12. f6 hxg3! 13. f7 g2 14. f8=Q+ Kg3 = The wKd6 blocks the check on the b8-h2 diagonal and so g2-g1Q cannot be prevented.
<b>7... Kc5</b> (7... Kd5 8. Kb5 and White has gained the opposition.)
<b>8. Ka4 Kc4 9. Ka3</b> Now Black must either allow the f4-f5 breakthrough or give up the opposition:
</p>
<p>
Main A:
</p>
<p>
<b>9... Kc3 10. f5!</b> echo with the breakthrough in main B
(thematic try 10. h5? gxh5 11. f5 h4 12. f6 hxg3 13. f7 g2 14. f8=Q g1=Q =)
<b>10... gxf5 11. h5 f4 12. h6 fxg3 13. h7 g2 14. h8=Q+ +-</b> Check!
</p>
<p>
Main B:
</p>
<p>
<b>9... Kd3</b>
<b>10. Kb3!</b> We have reached again the position after 3. Kb3, but now it is BLACK to move.
<b>10... Kd4 11. Kb4</b>
11. Kc2?! Ke4 12. Kc3 Ke3 13. Kc4 Ke4 14. Kc5 Ke3 just loses time
<b>11... Kd3 12. Kc5 Ke4 13. Kc4!</b> (13. Kd6? (or Kc6) 13... Kf3! = see the logical try 7. Kb7.)
<b>13... Ke3!?</b> Luring the white king to the d5 square.
(13... Kf3 14. h5 gxh5 15. f5 loses straightforwardly, the white king is too close.)
<b>14. Kd5 Kf2 15. h5! gxh5 16. f5 h4 17. f6</b> The a8-h1 diagonal is now closed, and so Black tries
<b>17... h3!? 18. f7 h2 19. f8=Q+ Kg2</b> Now, h1Q cannot be prevented, but White wins with
<b>20. Qa8!</b> Changing the order of moves is possible.
<b>20... h1=Q 21. Ke5+ Kg1 22. Qxh1+ Kxh1 23. Kf4 +-</b>
</p>
<p>
<i>As a strange coincidence, the key moment of this study has some similarity to that from the previous work. I guess everybody would try the natural 7. Kb7 but that is just a well hidden try. Winning is another amazing move to the edge of the board: 7.Ka5!! The position after black's 3rd move is a 'cyclic zugzwang': white's only way of winning is by returning to the same position but with BTM. A prize winning pawn study is a rarity nowadays but I consider it completely justified.</i>

Every year, the Judit Polgar Chess Foundation is organizing the <a href="https://www.globalchessfestival.com/index.php/en/">Global Chess Festival.</a> An interesting program during the festival is the Chess Artistry Adventure in memory of Pal Benko, a highly respected Hungarian-American grandmaster and composer, renowned for his awe-inspiring chess masterpieces.The Chess Artistry Adventure celebrates the artistic side of chess and honors the tireless efforts of composers who bring magic to the chessboard.
</p>
<p>
GM Judit Polgar writes: <i>"Chess studies and composers have played a pivotal role in my personal growth and development, enhancing my understanding of the game and expanding my artistic vision. The joy and inspiration that endgame studies bring to top chess players are widely known. As a way of giving back to the composers' community, I acknowledge their invaluable contributions to chess through various platforms, including masterclasses, courses, live commentaries, and festivals. I invite you to create a study composition inspired by a tournament game that captivates over-the-board players."</i>

<p>Just like last year, I have participated with a study based on a theoretically important queen endgame. My entries (please, click on the links):

Position A
</div>
<p>
This is the ideal position for the black pieces. This position was reached (with reversed colours) by Averbach in
the analysis of the game Schlechter - Pillsbury (Vienna, 1898). He couldn't prove the win, but later a winning method was discovered by Stalyoraitis (1980). I could prove that the method is unique in the sense that reaching Position B is essential to win.* The game Veselovsky - Bebchuk (USSR, 1977) also could have been decided by this, but it has ended in a draw. A flawed analysis of that game appeared in Benko's Laboratory (Chess Life, April, 1982). being my starting point to create this study.
<b>8. Qd7!</b> The shortest way to win. The other moves are time-waisting duals which all lead to the same key position.
<b>8... Qe4+! 9. Kb8! Qf4+ 10. Kc8 Qc4+ 11. Kd8 Qh4+ 12. Qe7 Qd4+ 13. Kc8 Qc4+ 14. Kb8 Qb5+</b> The black queen cannot stay any longer on the 4th rank.
<b>15. Qb7 Qe5+ 16. Ka8! Qc5</b>

Position B
</div>
<p>
Unfortunately for black, the ideal position of its pieces couldn't be reached anymore. The black queen is on c5 instead of c4, and that allows the following check:
<b>17. Qb3+!</b>
17. Qd7?! Qf8+ The position is still a win but white has to work hard to reach again the key position (B). A similar check will not be available at the end of the main line because the black king will be on f8.
<b>17... Kf8</b> The best chance is to stay on the 8th rank because there is no time to run with the king to the
lower half of the board.
17... Kh8 18. Qh3+ (18. Qb7? Qc3! = mutual zugzwang) 18... Kg8 19. Qe6+ Kh8 20. Qe8+ Kg7 21. Qd7+ Kh8 22. Qd8+ Kh7 23. Kb7 +-
<b>18. Kb7 Qe7+ 19. Ka6 Qd6+ 20. Qb6 Qd3+ 21. Kb7 Qd7+ 22. Ka8! Qd5+ 23. Kb8 Qe5+ 24. Kb7 Qe4+ 25. Qc6 Qe7+ 26. Kb8</b>
26. Ka8?! Qd8+
<b>26... Qb4+ 27. Ka8!</b> and black quickly loses because there is no check on the 8th rank. For example:
<b>27... Qf4</b>
27... Qb3 28. Qc8+ Kf7 29. Qb7+ +-
<b>28. Qc8+ Kg7 29. Qb7+ Kh6 30. Qc6+ Kh5</b> With the black king on the 4th rank, the position would be draw.
<b>31. Kb7 Qb4+ 32. Ka6 Qa3+ 33. Kb6 Qb3+</b>
33... Qe3+ 34. Qc5+ +-
<b>34. Qb5+</b> and wins.
</p>
<p>
*Proving that Position B is essential for the winning process was done
using the <a href="https://centaur.reading.ac.uk/23799/3/ACG13_2011_v4_Position_Criticality_in_Chess_Endgames.pdf" target="_blank">Haworth Method.</a> In the normal QP v Q tablebase both positions are
wins. By regenerating the tablebase from scratch with a 'seed' (Position B set
a priori to DRAW), one can see if that causes a change of the evaluation for
Position A as well (to DRAW) proving that the two positions depend on each
other.

Draw
</div>
<p>
Despite being blocked, the pawn is extremely dangerous. Black has a simple
winning plan: bring the queen to c1 after finding a safe square for the black
king (e.g. b8). This forces white to take immediate action by trying to give a
perpetual check.
</p>

Thematic try: 10. Bf1? Na5 11. Be2 c6! zz 12. Bh5 Nc4 13. Be8 Ne5! zz. Now the bishop cannot continue the merry-go-round anymore and has to return. Unlike in the main line, here it is not possible to attack the c4 square by Bb5 because of the line-interfering c6 pawn. 14. Bh5 d4+ 15. Kb3 Nc4 16. Be2 Na5+ 17. Ka3 Kb6 18. Kb4 c5+ -+

White has a disadvantage of two exchanges. In order to win, not only one but
both rooks should be captured. The awkward position of the black king gives
some hope to succeed.

<p>This study is based on a position found in one of the 8-man mutual zugzwang lists released by <a href="http://www.arves.org/arves/index.php/en/latestnews/latest-news/2-ongecategoriseerd/1509-8-men-tablebase-first-explorations">Marc Bourzutschky</a>. For finding that special position (see the solution after 3.Bh1!!), I have created a special version my software <a href="https://ruszchessstudies.blogspot.com/2021/02/syzygy-endgame-explorer-see-version-03.html">SEE</a> (Syzygy Endgame Explorer) to support some searches up to 8 pieces.
