patzer2 Member since May-20-03 · Last seen Sep-26-16 A former class A player over 25 years ago, I'm returning to studying chess as a hobby in retirement. Spending more time on end games and middle game tactics than openings now. I may try playing in tournaments again later, but for now I like the challenge of analyzing and trying to understand the subtlties of strong Master games.

Sep-26-16 Kramnik vs Mamedyarov, 2016   patzer2: The decisive error is apparently 46. h4? allowing 46...Kxa4 (-4.11 @ 26 depth, komodo 10) with an easy win for Black. Instead, 46. Nb8! = holds as play might go 46. Nb8! Kxa4 47. Nc6 Bc1 48. Nxa5 Kxa5 49. Kxe6 Bxf4 50. Kf5 ...      Sep-26-16 Mamedyarov vs I Nepomniachtchi, 2016   patzer2: Difficult in Blitz to find the best move. However, 13...e5 14. Rb5 Qa3 15. d5 Na5 = to looks OK for black.      Sep-26-16 M Pitz vs S Stark, 2009    patzer2: Took the 9. Qf5+ Kh5 (Kh6 10.Nf7#) 10.Nf7+ g5 11.Qxg5# route for my Monday solution. The shorter game continuation 9. h5+ Kh6 10. Nf7# is best. However, I'm not disappointed as I found the 9. Qf5+ mate quick and easy. Black's      Sep-25-16 Aronian vs Kamsky, 2013   patzer2: Quite well played for a Blitz game. The decisive mistake was 28...e6? allowing 29. Qh5+ (+15.97 @ 27 depth, Stockfish 6). Instead, 28...Kg2 29. Kg2 exd6 = (0.18 @ 19 depth, Deep Fritz 15) holds it about level.      Sep-25-16 Aronian vs A Volokitin, 2008    patzer2: What a great game for today's (20. ?) Sunday puzzle! Guessing the first couple of moves with 20. Ng5! hxg5 21. Qh7+ might not be beyond a club player's expertise, but finding the follow-up in this complicated King Hunt was ...      Sep-24-16 M Sion Castro vs Shirov, 1995    patzer2: The computers like <Shajmaty>'s 2008 suggested improvement 19. Qh5 (0.38 @ 23 depth, Stockfish 7). Also good is 19. Rh3 (0.34 @ 22 depth, Deep Fritz 15).      Sep-23-16 Jakovenko vs Gelfand, 2015    patzer2: <Once: Ooh, that's a good puzzle! I more or less got there, but I needed to turn to Fritz to understand all of it.> Here's my look with Deep Fritz 15: <50...Nd5+!> not 50... Qe2+? 51. Kd4 (51. Kxf4?? Qe3+ 52. Kxe3 + =) 51... Qd3+ 52. Kc5      Sep-22-16 Radjabov vs Jobava, 2015   patzer2: Good for at least a Friday puzzle is the surprise, defensive resource 24...Bg4! =. Other Black 24th move alternatives lose.      Sep-22-16 Carlsen vs E Cordova, 2016   patzer2: Instead of 37...Rf7?, allowing 38. Qe6 (+3.66 @ 32 depth, Komodo 10.1), Black could have held with 38...Qg6 39. Qxg6 Rxg6 40. Kxh2 = (0.07 @ 35 depth, Stockfish 7).      Sep-22-16 O Girya vs A Kashlinskaya, 2015    patzer2: I'm four out of four this week with my Thursday puzzle solution matching the game move 44...Rxb2!, clearing the way for the decisive advance of Black's passed pawn on e2. The line I calculated matched at least one strong computer program's continuation with 44...Rxb2 45. Nd4 e2
