Black has twice as much material than white so it looks very natural to start with a queen promotion: 1. e8=Q? a2 2. Rf6+ Kg2+ 3. Kc2 3. Kc4 Ra4+! 4. Qxa4 Rh4+ -+ 3... a1=N+! Black chooses to promote the pawn to a knight! 3... Rc3+? 4. Kd2 Rd5+ 5. Ke2 Rc2+ 6. Ke3 Rc3+ 7. Ke2 =

Variation A:

Let's go back to the initial position of the study.

The actual solution starts with a surprising sacrifice: 1. Rh6!! a2! 1... Rxh6 2. e8=Q a2 3. Qf7+! (3. Qf8+? Kg2 4. Qg7+ (4. Qxh6 a1=Q -+) 4... Rg6 5. Qb2+ Kh3 6. Qc3+ Rg3 -+) 3... Kg2 4. Qb7+! Kg1 5. Qg7+ Rg6 6. Qd4+ = 2. Rxh3+ Kg2

Thematic try: 1. Rf8+? Kg2 2. Rg6+ Kh1 3. Rf1+ Qg1 4. Ra1! Qxa1 5. Bxa1 c3+ 6. Kc1 c2 =

With the rook on g6, the g7 square cannot be used as a cutting point to avoid stalemate and there is no time for the critical move Rg6-g8.

Solution: 1. Rf6+! Kg2 2. Rg8+ Kh1 3. Rf1+ Qg1 4. Ra1! 4. Ke2? Qxf1+ 5. Kxf1 stalemate 4... Qxa1 5. Bxa1 c3+ 6. Kc1! mutual zugzwang 6. Bxc3? stalemate 6... c2 This time the rook is already on its right place so the stalemate can be avoided!

1. d7 Nd5! 1... Ba4 2. Nc6! +-; 1... Bf5 2. Ne6! +- 2. Ne6! Thematic try: 2. Nc6? Nc7+ 3. Kb6 Ne6 (position X') 4. Nd4! Ba4! = 2... Nb4+ 3. Kb6 Nc6!

position X

position X'

If we compare Position X with Position X' from the thematic try, it appears like the two knights were "repainted". This is the only difference between the two positions so the study features the WCCT-10 Theme in an original way!

4. Nd4! 4. Kxc6? Ba4+ = 4... Bf5! Black goes for a stalemate trap! 4... Nd8 5. Nxc2 +- 5. Nxf5 5. Nxc6? Bxd7 = 5... Nb8! 6. d8=B! +- 6. d8=Q? stalemate

The end position has a white bishop and knight vs. a black knight, while in the initial position of the study there was a white knight vs. black bishop and knight. It looks like during the game, paradoxically, all minor pieces were repainted!

White doesn't allow a black counterplay based on Rc8. 21... Kb1 22. Ra3! The only way to stop the pawn is by pinning. 22... Kb2 23. Rfa8 2nd thematic try: 23. Kd4? Rh3! 24. Ra7 Rh4+ 25. Ke5 Rh5+ 26. Kf4 Kb1! Black uses the poor position of the f8 rook which is obstructed by its own king. 27. Rb8 b2 = This try failed only because the rook was on the f-file so white will start a manoeuvre to reposition the rook to another file. 23... Kc2 Position X. Now the white king is closer compared to Position X' reached in the 1st thematic try.

Unlike the 2nd thematic try, now that the rook was repositioned from f8, this plan works.27...Rc2! Although the best square for the black rook is c1, black deliberately wastes a tempo before putting it there trying to play for a zugzwang. 28. Rga8 28. Ra4? Kb1 29. Rc4 b2 = Now we see the reason for moving the black rook to c2 instead of c7. With an unprotected rook, this pawn move wouldn't be possible. 28... Rc1 The threat 29.Ra1 had to be stopped. Now white seems to be in zugzwang but it still can win by transferring the move to black.

cyclic zugzwang - WTM

29. R3a4(5,6,7) White threatens to put a rook to the b-file. Beside occupying the first rank, this is white's other plan to win. 29... Kb1! Black aims for a fortress by trying to push the pawn. 30. Ra1+ 30. Rb7? b2 = fortress 30... Kb2 31. R1a3!

cyclic zugzwang - BTM

31... Rh1 Black has to keep the rook on the first rank. 32. R3a5(6,7) 32... Kb1 This is the last try to build the fortress. Now that the black rook has moved from c1, this move loses immediately. 33. Ra1+ +-
