| Dec-25-02 | | Andre: beautiful combination, 37. ...gxf6? leaves black facing mate, and 37. ...Qxf3?, white replies Nxd7+ ! |
|
| Dec-25-02 | | ughaibu: If he plays Qf3 white can mate by Re8. |
|
| Dec-25-02 | | Andre: True! I cant believe I missed that! Thx. :-) |
|
| Feb-16-04 | | patzer2: If 37...gxf6, then 38. Qxf6! (visualizing the threats for White in this position is the key to solving the combination) Qxg2+ 39. Kxg2 Kg8 40. Re8+ Rxe8 41. Rxe8+ Kh7 42. Qh8# If 37...Qxf3, then as <ughaibu> indicates 38. Re8+! Rxe8 39. Rxe8# |

| Feb-16-04 | | rochade18: 55. f3 is also a good one by Mr Repetto |
|
| Feb-16-04 | | Egghead: I don't know ... The losing lines are pretty, but Dus-Chotimirsky found the best defense, and it took White 18 moves (and several Black inaccuracies) to convert the win. It's not a decisive combination. |
|
| Feb-16-04 | | DexterGordon: That's a good point, Egghead.
I wonder if Black couldn't have offered more resistance after losing the Queen by retreating the King behind the f,g,h pawns. With the King exposed in the middle the White Queen really dominates. |
|
| Feb-16-04 | | JustAFish: It took me a while to see that after Qxf6, Qh8 is the mate threat. I found this one much tougher than usual |
|
| Feb-16-04 | | Shad0wl0rd16: yes!!! the only puzzle i've ever gotten so far!!! go me!! |
|
| Feb-16-04 | | patzer2: <Egghead> <It's not a decisive combination> Take another look at the position after 42. Qxa5  . I think it's decisive, due to Whites's pawn majority in this Queen versus Bishop and Rook ending. Perhaps more accurate is to state that the win is not easy and will require strong technique. Playing out the position after 42. Qxa5 as White against a computer should prove instructive. |

|
| Feb-16-04 | | Helloween: <patzer2> Since endgames are one of my stronger points, I decided to take up your suggestion here. I set the position up on Fritz 8 after 42.Qxa5 and played it out, giving each side 30 minutes to complete the game. I found the win as White to be quite easy due to the potential of the a and c pawns. The game had some nice moves if you want to check it out: [Event "Blitz:30'"]

I had 23:23 left on my clock and Fritz had 18:39 left. In conclusion, I would have to say that this combination is very decisive for White. |

| Feb-16-04 | | patzer2: <Helloween> Congratulations! Thanks for taking up the challenge and illustrating the win after 42. Qxa5. Fritz is a tough opponent, even in a "lost" position. |
|
| Feb-16-04 | | marcus13: I think 38. ... Nxd7 is easier to win isn't it? |
|
| Feb-16-04 | | Marnoff Mirlony: I saw the attack instantly. |
|
| Feb-16-04 | | mrvocab: You guys do know that Fritz 8 has a "shootout" analysis mode, don't you? You don't actually have to play one side to determine the relative strengths of a position. Fritz will play both sides, and you can specify the ply depth that it uses to search each move. I can also repeat the shootout at different ply depths, to confirm the analysis of the position. |
|
| Feb-16-04 | | mrvocab: White's last move, 55 f3, is also a good combination move. Black's bishop is forced off the a8-h1 diagonal, and so Black looses either the rook (56 Qc6+) or the bishop. |
