Andrew Chapman has kibitzed 608 times to chessgames   [more...]

Jul-30-25 Kashdan vs O Tenner, 1934    Andrew Chapman: Nice gradation, winning a pawn, then the exchange, then a piece.      Jul-29-25 A Graf vs S Kiselev, 1988    Andrew Chapman: 42.Bh5 Ke6 and the knight escapes. But white is still much better. Exchange off the knight, plant the dark squared bishop on c3, and the black queenside pawns can make no progress without help from the king. 42.f5 is best according to the machine.      Jul-28-25 V Rauzer vs Ragozin, 1936    Andrew Chapman: <somehow still pictured two rooks on the first rank>conversely, it took me some time to realise there was a second rook on a1. If I am not mistaken, the founder of this site sadly passed on, and I am grateful that it still continues at all. We now have to factor in that      Jul-24-25 L Rellstab vs L Steiner, 1937    Andrew Chapman: It's a nice puzzle to see that there is something better than Rxf8 (I didn't).      Jul-23-25 A Woodward vs G Rorrer, 2025    Andrew Chapman: 26..Ng4 a blunder?      Jul-09-25 E Vegh vs J Polgar, 1989    Andrew Chapman: I had Ne4 forgetting that black can defend with Nd5. Turns out it's quite good (+3) because the knight can go on to take on Nc5. Nh7 is less than +1 because of Nd5.      Jul-01-25 Abdusattorov vs P Maghsoodloo, 2025   Andrew Chapman: 27..d6 seems to have been the decisive mistake.      Jun-19-25 J B Bjerre vs X Xu, 2025   Andrew Chapman: Evaluation doesn't change after 30.Rd7 but I can understand that rook against bishop and three pawns seems more definitely lost than being a pawn down.      Jun-12-25 I Smirnov vs V Vetoshko, 2007    Andrew Chapman: <In the game line, the king is still tempted by refusing the B, following with: <25...Kxf6 26. e5+ Kf7> 27. Qg5 dxe5 28. Bxh7 exd4 29. Bg6+ Kg8 30. Bf5+ Bg7 31. Rg1 Rc7 32. Qg6.> 29.Bg8, elegant.      Jun-11-25 R Praggnanandhaa vs Gledura, 2025   Andrew Chapman: Apparently, 37. Qf4 was a mistake, bringing the evaluation down from +3 to 0. Then black needed to play 38..Qb8 rather than Qb7. But I don't know why I am afraid..
