   Nov-08-19 Yates vs Alekhine, 1924
kbob: According to Serper ( Nov 4, 2019) this game precipitated an incredible cascade of chess blindness. In his book "International Chess Tournaments in New York 1924 and 1927" Alekhine annotated 5.d4 b5 6.Bb3 Nxd4 7.Nxd4 exd4 8.Qxd4 c5 9.Qd5 Be6 10.Qc6+ Bd7 11.Qd5 Be6(??) as a ...
   Oct-13-19 R Kempinski vs Epishin, 2001 (replies)
kbob: re king sacrificer Is there a technique to drive a king to any corner? Here are some quick impressions that may help. (1) At first, the knight can get in the way, hold it back and use bishop and king to completely conquer the center (2) Notice that B and N screen out the opposing king ...
   Sep-27-19 Bosboom-Lanchava vs C Slingerland, 2000
kbob: My guess it was time pressure and flag fall.
   Sep-21-19 A Lein vs Tal, 1955
kbob: Black had some of the elements of a fortress draw ( i.e. proper pawn guarding rook with king nearby) but the white king is behind the pawn and this guarantees the win.
   Sep-16-19 Morozevich vs Jakovenko, 2006
kbob: Morozevich, Svidler, Navarra, Meier. These are really monster names not to have this ending at their fingertips.
   Sep-12-19 Spassky vs Korchnoi, 1977 (replies)
kbob: Perhaps not relevant here, but according to my faulty memory Spassky said of Korchnoi: "He taught me not to push my pawns." I try to keep that in mind when I go over their games. Also, it seems to me that Spassky preferred isolated queen pawn positions for their own sake. Shades of ...
   Sep-07-19 Kindij vs Ivkov, 1951
kbob: At move 114 White had the key position to break down the third rank defense. But the forced mate in 19 moves beginning with 114. Qe3 ! is not at all intuitive. In "Secrets of Pawnless Endgames" John Nunn says if you take nothing else from the chapter it should be to memorize this ...
   Aug-22-19 Larsen vs Spassky, 1970 (replies)
kbob: Just for comic relief, Stockfish proclaims 14. ...Rh1 third (!) best after 14. ...Qh4 and 14. ...Bxe3.
   Aug-01-19 Gligoric vs Ulf Andersson, 1977
kbob: Thanks to perfidious for his comment and apologies to all for truly garbled analysis. Here is a second attempt based on lifetime records from this website Lifetime drawing percentages in classical games Ulf Andersson 63.7% Petrosian 55.0% Gligorich 49.6% Schlechter 46.9% (ie ...
   Aug-01-19 T Bergs vs Vladimir Petrov, 1937
kbob: Yes you cannot draw by resigning! Although the endgame is ultimately a database win for black, even the mighty Reuben Fine botched his analysis tree in BCE (p 47) and had to be corrected by Benko in the 1993 edition. When I was a kid, it seemed there was an errata to BCE in Larry Evans
