Mar-18-22 Budapest Candidates (1950) 
| |
| LRLeighton: The supposed motivation for Boleslavsky to let Bronstein catch up was that the two players believed that if they tied for first, then FIDE would organize a World Championship Match Tournament involving Boleslavsky, Bronstein, and Botvinnik. Botvinnik liked match tournaments, and ... |

Mar-09-22 Rapport vs Vachier-Lagrave, 2022
| |
| LRLeighton: This is a theoretically important game in the Grunfeld. Although the variation with 12 Rc3 has been seen before (although it doesn't show up in the CG database), it has never previously been played by 2700+ players. The "normal" moves have been 12 Qd2, which leads to a typical ... |

Mar-02-22 Kamsky vs Anand, 1995
| |
| LRLeighton: The game-score is wrong. White's 19th move was actually Rb2, which makes much more sense. I'm submitting a correction slip. |

Feb-23-22 J Kristiansen vs Deep Blue, 1993
| |
| LRLeighton: To be fair, Nickel was allowed to play as a centaur, specifically, he could use chess software that he could purchase over the counter. So he bought a $60 package of Fritz, which at the time, was weaker than Nickel was. So it's unclear how much Fritz helped him with his analyses. |

Feb-17-22 R Skomorokhin vs Aseev, 1994
| |
| LRLeighton: Black overlooked a win when he played 33...Rd8. Instead, black should play 33...Rca8, threatening mate starting with ...Ra1+. If white plays 34 Kd1, then 34...Nxg2+ wins a rook, and if 34 Kb1, then 34...Nxg2 still wins material. |

Feb-07-22 J M Lopez Martinez vs J Guerra Mendez, 2017
| |
| LRLeighton: Hi TJ: That's weird; I just happened to check out this game again and saw your kibitz from a few days ago. There were several Tanglewood Opens, but I think that the first one was the one that Perfidious and I both played in, back in 1978. I think (?) that it ran every year after ... |

Jan-30-22 L Rojas Keim vs Leitao, 2005
| |
| LRLeighton: Actually, Luis Rojas not only could have drawn much earlier, but he could have won much earlier -- he missed a mate in three, with 33 Rxf8+! (removing the defender), Rxf8 34 Bg7+, Kg8 35 Nh6 mate. Very pretty suffocation. Too bad. |

Dec-16-21 Kotronias vs J Gallagher, 2010
| |
| LRLeighton: I suspect that Kotronias was in time-trouble, and that he probably lost on time, but on his last move, he missed a beautiful open-board forced mate with 39 Qf5+!, Bxf5 40 Bxf5+, Kd5 41 Rd1+ with mate to follow. |

Dec-09-21 Flohr vs Kasparian, 1947
| |
| LRLeighton: Flohr missed a win on move 38 and again on move 39 (as he could have repeated moves to reach this position). 38 Rf6+, Qxf6, and now not the immediate 39 exf6? when black draws by perpetual, but the clever intermezzo 39 Qe8+!, Qf7 40 Rc6+, Kh7 41 Qxf7 leaves white a rook up and ... |

Dec-05-21 Carlsen - Nepomniachtchi World Championship Match (2021)
| |
| LRLeighton: The soccer analogy holds. If the WC had an overtime like basketball, it would mean continuing to play classical games for a set number of games, which would be fine. But instead we have something like soccer -- just as penalty kicks do not have anything to do with the better team |
