Oct-09-08 Tolush vs N Kopilov, 1954 
| |
| Marco65: 22.Ng3 might not be the best defence but is probably the one that most requires precision on Black's behalf to win: 22...Rf4! (22...Bxd1 23.Bxb4 Bxb3 24.Qe6+ Qxe6 25.dxe6 Bxe6 26.Bxe7 Rf2 wins but less convincingly, and 22...Bf3 23.Qe6+ is similar) 23.Qg2 (to cover c2, otherwise ... |

Oct-03-08 Forintos vs V Tomovic, 1957
| |
| Marco65: <kirchhoff> 38.Qe8+ Kg7 39.Qxg6+ Kf8 and now? 40.Qf6+ Kg8 41.Bc4+ Bd5 end of fun, maybe 40.Qxh6+ ? |

Sep-30-08 D Minic vs K Honfi, 1966
| |
| Marco65: <kirchhoff: After 23. Qa7 Qc8 it looks like 24. Qxa8 leaves white a clear rook up> it's even more than that, Black has to lose other material not to get mated. E.g. 24...Rf8 25.Qxc8 and black can't take back the queen, or 24...g6 25.Rxd8+ etc |

Sep-10-08 Petrosian vs A Matanovic, 1959
| |
| Marco65: <al wazir> <black has nothing better than 29...g6 30. Rd8+ Kg7 31. Bb2+ Kh6 32. Qh3#> In your (and Dr J's) line (24. bxc7 d5 25. Qc2 Rc8 26. Qc6 Rxc7 27. Qxe6+ Rff7 28. Rxd5 Rxc1+ 29. Bxc1) 29...h6 or 29...Qc7 might stop the threat and hold the piece, but of course ... |

Jun-23-08 Keres vs R G Wade, 1954
| |
| Marco65: This is the Alekhine-Chatard variation. Today Black rarely accepts the pawn sac. I don't remember exactly theory, 9...a6 seems a bit too slow, but I do remember that the 2 standard ways to defend g7 are ...g6 and ...Kf8. ...O-O is an option no player of this variation would ever ... |

Jun-20-08 B Ivanovic vs Velimirovic, 1981
| |
| Marco65: To be precise, 24...Bxc4 25.Qxf6 doesn't mate, but gains another piece after 25...Kf8 26.Qxg7+ Ke7 27.bxc4 |

Jun-20-08 J A Fernandez vs R Garbarino, 2001
| |
| Marco65: Every QGD player knows a similar trick: 1. d4 d5 2. c4 e6 3. Nc3 Nf6 4. Bg5 Nbd7 5. cxd5 exd5 6. Nxd5? Nxd5! 7. Bxd8 Bb4+ but maybe a player of the English can fall into the trap |

| Marco65: Nobody else played 9...Nxc4 here, and there must be a reason! |

May-06-08 M Feigin vs Flohr, 1937
| |
| Marco65: It's funny how 39.Rf1 which seems to prevent 39...Nf2+ is exactly what allows it. Maybe 39.Rbc3 with the idea of 40.Rf1 can hold. If 39...Reg6 40.Qe2, if 39...Rge8 40.f4 but I get the feeling there can be more for Black. |
