Jun-20-23 Gheorghiu vs Sax, 1972    NBZ: <Brenin>: Two quiet but deadly moves. Would be so hard to spot in a game, especially as Nf4 is so tempting.      Dec-31-22 So vs N Ginting, 2008    NBZ: Alas, I missed that the queen on a5 guards d8. So I thought 31. Ng5 Rxc2+ 32. Qxc2 Nxc2 33. Rd8 is mate (when it only leads to a draw, as <Vermit> points out). I did find a cool line if Black tries to defend from 31. Ng5 with 31. ... Qf5. Everything seems defended, until you ...      Oct-20-22 A Reggio vs H Fahrni, 1905    NBZ: Alas, <poorthylacine> who spotted this beautiful queen sac that became a puzzle does not seem to visit CG anymore.      Oct-15-22 M Rohde vs Benjamin, 1977    NBZ: That is one sharp game. The finish is very neat.      Sep-09-22 Aronian vs V Nevednichy, 1999    NBZ: <Brenin>: Agreed, I think 40. ... Kf8 is the critical line, and is the one that I was most worried about before finally seeing that 41. Rxe6 Qxe6 42. Qh8+ Qg8 (Kf7 Rh7#) 43. Qf6+ Ke8 (Rf7 Qxd8+; Qf7 Rh8#) 44. Rh8 wins. Without this line, the combination simply does not work ...      Jun-15-22 de Firmian vs Yudasin, 1990    NBZ: I also had 19. Nxe6 Rxe6 20. Nd5 Qa5 21. Ne7?? Rxe7 22. Qxe7, which wins, of course. But 21. Ne7 still gets a double ? because how often in your life can you play a move like 21. Qe7!!      Jun-06-22 A A Zaremba vs R Antonio, 1995    NBZ: <Brenin>: Agreed about 16. h3 being an error. But the big mistake for me came at move 13, just castling straight into the inevitable attack. An intriguing alternative is 13. d5 exd5 14. Nd4.      Mar-23-22 Xiong vs Shabalov, 2017    NBZ: <NBZ: I found this really difficult, and just could not find Qb6.> Note to self: evidently, I have not changed in the last 4 years! I found this just as difficult. At least I "saw" the Qb6 idea this time, but managed to convince myself it didn't work. Alas.      Mar-07-22 R G Wade vs R F Boxall, 1953    NBZ: <Skewbrow><raymondhow>: Nh5 is indeed interesting. After Nh5 Rxh5 Rxf7, White has to play the obvious Rxe5, and avoid the tempting Ng6+?? Kg8 and now White even loses because of the mate threat. Example: Nxe7+ Rdxe7 Rd1 Rxf1+ Qxf1 Qxh5 picks up a rook. Or Nxe5 Rxf1+ Qg1 ...      Feb-27-22 J Hector vs R Ziatdinov, 1994    NBZ: I chose Bc7 too. It seems to lead to a dominating position for White in all lines: 18. Bc7 Qxc7 19. Nxd5 Qd8 20. Rfe1 Ra7 21. Bxc4 bxc4 22. Qxc4 and Black's position is hopeless: a pawn down, bishop pinned to the king, no way to castle etc. 18. Bc7 Qd7 19. Nxd5 Qxd5 20. Rfe1 and either ...
