Feb-21-21 O Bernstein vs Nimzowitsch, 1914 
| |
| CharlesSullivan: This is a very famous game: Chernev called it the "most brilliant drawn game ever played"; Martin Beheim called it "almost the ideal game of chess." Modern computers show that Black needed to play 25...f4 because White had a win at move 28 that has been overlooked for 107 ... |

Dec-09-18 Alekhine vs Capablanca, 1927
| |
| CharlesSullivan: Note: I am submitting a second correction slip -- Black played 44...Qe8 in this game, NOT 44...Qf8. At least, that is what Skinner & Verhoeven (Alexander Alekhine's Chess Games, 1902-1946), Alexander Alekhine (My Best Games of Chess 1924-1937; On the Road to the World ... |

| CharlesSullivan: < Stockfish's losing move was 34...Rd8 >
[ The following analysis was posted on the Rybka Forum on Dec. 24, 2017 ] :
Please note that Black has a draw as late as move 34. After an overnight search of 65 plies, Stockfish8 (with endgame tables) rates 34...a6 as ... |

Oct-17-18 Spassky vs Fischer, 1972
| |
| CharlesSullivan: <Howard: ... how many forced wins did Bobby miss?>
After Spassky's blunder at move 31, Fischer maintained a winning position until he missed 38...Rd1. So I would say that Bobby missed only 1 forced win.
If your question is, How many (ill-defined) "better" moves ... |

| CharlesSullivan: < Further Errors, But -- No Harm, No Foul >
After Fischer escaped retribution for his 20.Bf4 blunder, he thought for 8 minutes and landed in the soup again with another weak move: 21.Bb5 lost a pawn to 21...Qxb2 22.Bxc6 Nc3! Stockfish says that White should have ... |

At move 36, where Black played 36...b5 (which would have allowed White to equalize with 37.c4) [see analysis above] , I first looked at 36...Red8
