   Sep-24-22 Kupreichik vs Huebner, 1970
nummerzwei: In his book <Twenty-five Annotated Games> (1996), Huebner tried to prove an opening advantage for White with 13.a3 Bxc3+ 14.Nxc3, after which 14...h5 is the only move considered. The more logical 14...0-0 had already been played in Keitlinghaus vs E Heyken, 1995 : [DIAGRAM]
   Sep-10-22 Ponomariov vs Carlsen, 2010
nummerzwei: <notyetagm: 41 ♖d5xa5=> [DIAGRAM] <GreenFacedPatzer: <To me, the remarkable thing in this game is the progress from say move 39 (where the position is perfectly symmetric, surely a draw!) to move 83 (where black's advantage is overwhelming.) How many grandmasters ...
   Sep-06-22 Firouzja vs Mamedyarov, 2021
nummerzwei: In his 1973 book <Practical Chess Endings>, Paul Keres gave an exhaustive(!) account of pawn endgames such as after 48...Rf3 49.Rxf3 exf3. There are 35 possible configurations, eleven of which admit draws even if the stronger side's king is close. In the game Shirov vs ...
   Aug-25-22 Kotov vs Unzicker, 1952
nummerzwei: < SimonWebbsTiger: Kotov included this game in his book "Grandmaster at Work"; the ever great Jimmy Adams translated a 1962 Russian book for publishers American Chess Promotions, 1990. Kotov didn't think much of 16...h6 and suggested 16...c4, giving 17. Qc2 b5 18. e4 g6 19. ...
   Aug-25-22 A Kujala vs D Smit, 1989
nummerzwei: After 36...fxg6! there seems to be no win for White. In the game continuation, too, some ingenuity is required: After 37...f6, [DIAGRAM] it seems that White can win simply with 38. Rf5, followed by taking his king to the queenside, but there is subtle defensive idea: 38.Rf5?! ...
   Aug-11-22 Quinteros vs Ribli, 1974 (replies)
nummerzwei: <Amorim: Why not 10. b4? How does black prevents loosing one of the knights?> Well, Black has the fork 10...Nb3. Nevertheless, it is a move that comes into consideration. In his collection of miniatures <Grandmaster Secrets: Winning Quickly at Chess>(2007), John Nunn ...
   Jul-24-22 Onischuk vs Timman, 1996
nummerzwei: White could (and should) have wiped out the pawns with 56.g7! Rxg7 57.Kc4 Rg4+ 58.Kc5, followed by 59.Bc4 and 60.Kxb4. After the game continuation, the position is drawn, but Black could have played on with 65...Rg2+ 66.Kb3 Kc5.
   Jul-19-22 O Bruk vs Salov, 1983
nummerzwei: < Chess Classics: Did Brouk flag? I can't see a win for white... Regards, CC> Me neither. Seriously speaking, White's decision to resign is quite unremarkable. After the natural 78.Kf3 Nxa3 79.Kxf4 Nc4 [DIAGRAM] White's king is outside the square of the a-pawn, while ...
   Jul-09-22 Shankland vs Burke, 2021 (replies)
nummerzwei: What has always bothered me about this game is that, after 46.Kf4, a position arises that is identical to the "classic" [no game-score appears to be available, just the endgame] Ghitescu - Rajkovic, Skopje 1984: [DIAGRAM] Here, Rajkovic played (with the move numbering from the ...
   Jul-08-22 Thai Dai Van Nguyen vs R Vogel, 2022
nummerzwei: [DIAGRAM] After an arduous defense, Vogel's 84...Ra8? misses White's next move and loses the g-pawn into the bargain. There were two alternatives. If Black plays the crafty 84...Nh8!? in order to cover the g6 square, he gets hit by 85.Nxh6!! gxh6 86.Rxh6: [DIAGRAM] It is easy to ...
