Dec-04-12 Bird vs Meitner, 1882    der623: <Knight13> If Black plays 20...Nxa3, White plays Nxb6+ forking King and Rook.      Dec-04-12 G Timoshchenko vs J Bednarich, 1997    der623: <Phony Benoni> In your final position, White could play 36. Qc6+ and then promote the c pawn because if Black plays Qf4+, White can play g3 because after Black's Queen takes on f2, White can interpose his Queen on g2.      Nov-14-12 Kharlov vs Krasenkow, 1997    der623: Why not 26 Qa3? 26...Re4+ snares the Queen with the discovery.      Nov-13-12 Castellvi vs Vinyoles, 1475    der623: Black's first mistake was 5...Bg4 because White could have played 6. Bxf7+ winning a pawn because 6...Kxf7 is met by 7. Ne5+ recovering the Bg4 bishop with a double attack.      Oct-31-12 Hill vs Janeway, 1946    der623: <sambo> 10...Nh6 doesn't solve everything because 11. Rxf8 is mate because the Queen is pinned.      Aug-22-12 J Mullon vs Tkachiev, 2012   der623: Why did White resign? I think he just realized that Black was going to play 40. c6 which would cause White to drop the exchange. d6 is covered by the f8 Bishop. d7 and d8 drops the Rook by a Rook check on d2. e5 also drops the rook because of the same Rd2 check (Followed by a check ...      Aug-09-12 C Maier vs Kasimdzhanov, 2011    der623: This is the kind of game you would attribute to Nezhmetdinov. I am a little disappointed that White, a modern day GM, didn't sense that something was up after 34. Bxf4. There is the possibility that White did see what was coming and decided to let Black have his moment.      Jul-25-12 S Levitsky vs Marshall, 1912    der623: One of my favorite game enders is 31. Bc7 from Tarrasch vs. Allies in Naples 1914 (This was GOTD on this site on 06/26/09). I can't think of another move that surpasses Tarrasch's in subtlety and sophistication.      Jun-05-12 Wang Yue vs Yifan Hou, 2012    der623: To Whitehat1963: There isn't a perpetual. White plays 71. Kg2 and then queens on the next move. Black will not have time to get her King out of the way of her Queen and avoid a check from one of White's Queens. If Black doesn't move her King, and tries to check with just her Queen ...      Mar-26-12 Fressinet vs M Jurcik, 2012    der623: I give Black credit for seeing that his position is completely lost. If 36. Re8 37. Rxf7+ Kxf7 38. Qf6# OR 36. Kg7 37. Rg3+ wins a Rook because on Rg6 37. Rxg6+ the f7 pawn is pinned, and if the King recaptures, the g8 rook hangs.
