   Aug-02-21 Robatsch vs A Kostjoerin, 1960 (replies)
jes47: <Gregor Samsa Mendel: <buckmeister: White can win the Black Q for a B with 28. BxRh8 Kxh8 29. Qe5+ K(any) 30. Ra3.> I think in this line the black queen can escape after 30..Qc4 or 30..Qd5.> Medel is right, but Black does not merely escape. After 30 Qd5 Qd5 31 Bd5 Ra6 ...
   Jun-23-21 Vidmar vs Przepiorka, 1906 (replies)
jes47: The commentary gives 35 ... Re6 as best for black, but much better is 35 ... f5. The recommended line continues 36. Qf5 Rc6 37 Qd3 Rb6, which is a very strange move. In this line 37 ... c2 is crushing. They can't be using a current version of stockfish, or they have it set to a low ...
   May-01-21 Short vs Piket, 1990 (replies)
jes47: Like some other commentators, I would have played 22 Qd4. Although the variations are quite complex, Stockfish rates this as a winning move for white. So Nigel missed both 22 g6 and 22 Qd4. Everybody has a bad day, but why would pick a game marked by a blunder as a ...
   Jul-28-20 I Panagopoulos vs Stefansson, 1993 (replies)
jes47: The move order doesn't matter. Black wins just as decisively with 28... Qd2, threatening 20...Rf3. Now stockfish gives the best defense for white is 29 Nc4 Qg5 and white has nothing better than throwing away a bishop with 30 Bg4 Qg4 and black is up a rook, threatening mate.
   Jul-26-20 Dvoirys vs Timoshchenko, 1988 (replies)
jes47: The obvious 31 Nf7 gives a more elegant ending, and according to stockfish is stronger. 31 ... Kg8 is forced and after 32 Nh6 gh6 (if 32 ... Kh8 then 33 Qf5) 33 Qg3 Qg7 34 Qb8 is overwhelming.
   Jun-07-20 A Marthinsen vs Denker, 1992 (replies)
jes47: <perfidious> <al wazir> I played Denker numerous times at the Manhattan Chess Club weekly rapids in the 1970s. At his best I couldn't touch him but he was inconsistent. I was a strong A and I managed to take a few games off him. So it's not that strange for him to lose to ...
   May-31-20 A Iljin vs Nepomniachtchi, 2007 (replies)
jes47: Fatal error is at 17 ... Ra7. As RandomVisitor pointed out, 17 ... Ne5 preserves equality. After 17 ... Ra7 the position is irretrievably lost. As to Al Wazir's question about about 16 ... dc3, Predrag gives a good line in response, but my analysis rejects his 22. Bf5. Better is 22. ...
   Sep-05-19 Alekhine vs Opocensky, 1925
jes47: Alekhine was certainly more efficient, but I varied with 26 Rc7 and stockfish agrees that it's a decisive win. e.g. 26 ... Rh7 27 Qf6 Rc8 28 Rf7 Rf7 29 Qg6 +-
   Aug-11-19 Kasimdzhanov vs I Cheparinov, 2009 (replies)
jes47: No seems to have posted an easy refutation. After 26 Rd7 Bc3 27 Qe6 Bd5! is equal. For example 28 Rf7+Kh6 29 Qd7 Bg7 30 Rg7 Ng7 31 Rc7 Qb2 32 Qd5 Qe2 33 Nf7+ Kh7 34 Ng5+ Kh6 and stockfish gives the position as dead even.
   Jul-20-19 Timman vs Cherniaev, 2008 (replies)
jes47: In response to Al Wazir. It is more difficult than you describe because you do not give the best line for black. After 29 Re3 black has an easy draw after 29... gf6 30 Kf2 Qe4 and perpetual check becomes unavoidable.
