   Jan-06-22 Yakov Isaevich Neishtadt
nummerzwei: His books on chess combinations are a real joy.
   Jan-06-22 Kramnik vs Anand, 2001
nummerzwei: In his notes, Ivan Sokolov refers to White's queen development with 11.Qd2 and 13.Qf4 as <a quite fresh idea>. In this particular position, that may have been the case; the same setup was already seen in Szabo vs Unzicker, 1954 . That game may have inspired Kramnik - or ...
   Dec-30-21 Petrosian vs Polugaevsky, 1970
nummerzwei: This second of Petrosian's two wins in the playoff match for the 1969 Soviet title feels like a typical Capablanca, Smyslov, or Fischer game. That is, Petrosian outplayed his opponent from a relatively open position that is not so typical of him. Polugaevsky played rather ...
   Nov-21-21 M Kursova vs S Zaksaite, 2001
nummerzwei: I recently had the position after 16.Bc1 as Black in an online game. Instead of 16...Nxc3?!, I continued 16...Ra8!? 17.Ne4 Rc8 with equality.
   Nov-21-21 Karpov vs K Georgiev, 1994
nummerzwei: In his book <Winning Chess Middlegames> (2009), Ivan Sokolov gives the following as an alternative to the 28...Rf8, ultimately concluding it doesn't change the outcome: 28...Rxe4 29. Bxf7+ Kh7 30. Rxe4 Bxe4 31.Rxe4 Nf8 32. Ne5 Bxe5 33. Rxe5 Qxd6 34. Rd5 Qe7 35. Bxg6+ Nxg6 ...
   Nov-19-21 H M Klek vs Z Gaal, 2021
nummerzwei: Black's appeal to the fifty-move rule was correct: The precise wording of the rule demands a sequence where both sides have made fifty non-zeroing moves. The sequence starts at 61...Kh5 and so extends to 110...Kh8 for Black, whereas White's moves are those from 62.Ndf6+ to ...
   Nov-15-21 I Sokolov vs Khalifman, 1994
nummerzwei: In <Winning Chess Middlegames> (2009), Sokolov proposes 19...Bd6 instead of 19...d4, but this is likely no improvement: White has 20.Bxd7 Bxf4 21.Bxf6! Qxf6 22.exf4 Rxd7 23.Qxc5 Qxf4 24.Nd4 with a superior position.
   Nov-15-21 Portisch vs Karpov, 1978
nummerzwei: <A strange game. 17..Bxf3 was incredibly risky if found otb. Portisch’s 19 Qg3!? is not so bad but he needed a more vigorous & consistent follow-up eg 19..exd4! 20 Bf4 Qc6 21 Bxh6! Nh5 22 Qh3. If by this point Karpov was out of prep, defending would be challenging. > Your
   Nov-10-21 Caruana vs Vachier-Lagrave, 2021
nummerzwei: For some time, I have wanted to do a post on this endgame. Let me start with a digression: Suba - Chiburdanidze, Dortmund 1983 (after 104.Ke2) [DIAGRAM] Another endgame with N+f against R+g, which is clearly relevant to the positions that arise in the present game after 50.Rxa6. ...
   Nov-10-21 Korchnoi vs Averbakh, 1955 (replies)
nummerzwei: In <Fundamental Chess Endings> (2001), 53.Kf2 Kd5 54.Ke3 Bc5+ 55.Ke2 Kd4 56.Ne1 e4 57.Ng2 Ke5 58.fxe4 fxe4 59.Kd2 Be7 60.Ke2 Bg5 61.Kf2 Kd4 62.Ke2 is given as the game continuation, with a draw.
