Apr-12-09 Areshchenko vs A Volokitin, 2004 
| |
| apoka: <What if black tried 21...a5 and if 22.a3 a4? Would white have to try that same combo again (22.Rxf7)?> The deflection move b4 no longer works (Black can take en passant), so the combination will not work well anymore, i.e. Rxf7 still wins, but not as quickly. |

Apr-11-09 Shirov vs Movsesian, 2005
| |
| apoka: When I first looked at the puzzle, White did not look very strong with the bishop and rook under attack and only very limited king safety. I found hxg7, but missed the refutation Qh5 (which is probably the only move saving Black). I did not really have time to look in detail at other ... |

Mar-30-09 M Rogan vs J Rizzitano, 1989
| |
| apoka: @<c o r e>: It is probably not necessary to see the mate in 6 to solve the puzzle. In my opinion, it is sufficient to see that all reactions to Qxa3 result in a quick mate or a decisive loss of material (queen vs. knight plus the option to get another rook). The mate in 6 is a ... |

Mar-25-09 V Malakhatko vs Timoshenko, 2003
| |
| apoka: This time the winning moves were the first ones I tried. A very nice combination indeed. Looking at the game, I find 9. Nh3 a quite awkward move. It wastes a lot of time and allows Black to build up a strong initiative. What is the motivation behind this move? Why not 9. Nf3 instead? |

Mar-23-09 L De Veauce vs Keene, 1963
| |
| apoka: Just found another nice continuation: After the strong 6. e4 Black could play Nf6. If exf5?, then Bg3+ 8.hxg3 Qxg3+ 9.Ke2 O-O. Black is down two pieces and a pawn(!), but the opponent is disorganised and Black can draw or maybe even win by hunting the king over the board and ... |

Mar-20-09 Tal vs E Nievergelt, 1959
| |
| apoka: Accidentally, I left my computer in analysis mode when I left home. So here is the Toga II evaluation after a couple of hours (now running somewhere at 20 ply): 1. Qh6 +4.66
2. Qg5 +3.96
3. Qf4 +3.95
4. Qc1 +0.00
5. Qe2 +0.00
It is interesting to see that Qf4 is also strong, ... |

Mar-16-09 Areshchenko vs J Rapport, 2009
| |
| apoka: Why did Black resign? All pieces are save and he has a space advantage. To be honest, I would even prefer Black in this position. Quite dubious. |

| |
| apoka: Sorry, that was because I tried to manually create the FEN. It's probably better to use a chess program and copy the FEN from there. Fixed position: [DIAGRAM] Hint: It is mate in ten. (Figuring this out is challenging even for chess engines, so in human mode it is sufficient to find ... |

Mar-15-09 Bologan vs P Schlosser, 2004
| |
| apoka: That puzzle was quite hard. I analysed two moves in detail (as good as possible without moving pieces) from seven candidate moves (fxg7, g5, Rff3, Qd3, Be3, Bc5, Kg2): The first analysed move is 20. Rff3. The reply 20...Nxd4 can be met with Rh3. If White continues to capture with ... |
