| Sep-17-06 | | kinghunt72: Mariotti played pretty well until move 27. He should have protected is bishop with 27. Be2 Rfd8 28. Rxd4 Rxd4 29. Qg5. And White still could have recovered the loss of his bishop on move 29 by forcing Black's king out of its position. Black did not think of playing 30... Kf7 31. Qe6+ Kg6, where White wins the f-pawn with 32. Re5. For some reason I can't find any better combination for black. Someone tell me if they can find any. |

| Nov-16-10 | | Al2009: This game, along with several others, proves that Karpov - although one of the best strategic players ever - cannot pretend to be considered the very best all time, like Fischer, Kasparov, Alekhine, Tal, Morphy etc., due to his lack of "killing instict" , and understading of tactical chances. Now, in this game Black got a clearly won position at 20th move. But then, after 20.Rad1, Black started to play slowly, and wasted his huge advantage, by playing an insignificant move like 20...a5?!. Black wasted a big tactical chance. If he played 20...Ne4!, now after both 21. Qe3 and 21. Qc2, there is the crushing sac 21... Nxf2! followed by 22...f4! and White cannot hope to survive to the powerful attack of heavy pieces + Bb7 against his exposed King. This kind of Knight sac and attack is somehow reminiscent the wonderful one played by Fischer against Robert Byrne in the 1963-64 American Championship that he won 11/11. (15...Nxf2!) And so, it seems that Karpov wasted here a tactical chance to make the game last very less than 70 moves. |

| Nov-16-10 | | anandrulez: Al2009 , 21.a5 is what you mean , stockfish suggests 21.e4 with -0.7 and Ne4 is given draw . Also Nxf2 seems to be a blunder after Qc2 Qa3 or any other square for white q |

Forget stockfish...show me the correct analysis of what you're saying if you can, but you cannot, you're in error YOU made a blunder, not me. This kind of unbalanced longterm sacs is not in the standard evaluations of softwares like "stockfish". After 21...Ne4
if a) 22. Qc2 Nxf2! 23. Kxf2 e4 24.Nh2 f4 25. gxf4 Qh6! 26. Rh1 Qxf4+ 27. Nf3 (forced) Rf5  If b) 22. Qe3 Nxf2 and now b1) 23. Kxf2 e4 24. Nh2 (24. Ng5 f4! 25. gxf4 Qh6 26 Nh3 g5! ) f4! 25. gxf4 Qh6 26. Ng4 Rxf4+ 27. Kg1 Qg5 28. Nf2 Ref8 29. Rf1 h6!(with idea Rxf2) 30. Qb3 e3 31. Qxb7 exf2+ b2) 23. Qxf2 e4 24. Nh2 (forced 24. Ng5 h6 25. Nh3 g5 with idea 26...e3! and Qc7 and Black wins) g5! and Black's pawns steam roller is really devastating for White (immediate threat is e3 and Qc7) c) 23 Qa3? (the worst!) Nxf2! 24. Kxf2 e4! 25. Nh2 e3+! 26. Kg1 Qc7 27. Nf1 f4! I repeat, show me the analysis...it's time you begin to distinguish between a good sac and a blunder. |

| Nov-17-10 | | Al2009: Ah, 2 little corrections...
After 21...Ne4
if White plays 22. Qc2 (variation a), or 22.Qa3 (move number 22.Qa3 and not 23.Qa3, as written above in variation c) then 22...Nxf2! sac seems really winning (if there is a defence, let me know it) But if White plays 22. Qe3 (bad location to place the Queen, Black gains a tempo), it is not necessary to sac, it is enough to play 22...f4! and after 23. gxf4, exf4 24. Qa3 g5! seems very good for Black. At the end, after 21...Ne4! Black seems to be at least -4.0 points advantage, not just -0.7 as evaluated by stockfish |
