patzer2 Member since May-20-03 · Last seen Sep-22-17 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-22-17 V Fedoseev vs D Bocharov, 2016   patzer2: For today's Friday puzzle (23. ?) it seemed obvious that White needed to play 23. Rxc6! to get rid of his awkwardly placed Rook and eliminate one of Black's strongest defenders (i.e. the light square Bishop.) After 23. Rxc6! Qxc6, I should have seen Fedoseev's strong follow-up 24. ...      Sep-21-17 Von Der Lasa vs Staunton, 1853    patzer2: Two aspects of today's Friday puzzle (22...?) and game which I found interesting were: (1) The win missed by one of the greatest players of this time, Howard Staunton, with <22...Na2+! 23. Kd2 Rxe4! -+.> Stockfish 8 gives the following winning line for Black: <22...Na2+! ...      Sep-20-17 A Muzychuk vs S Brunello, 2014    patzer2: <Richard Taylor: <FSR: I saw 29.Nc6 Qe8 30.Qh3+, but didn't see what to do after 30...Be6. The answer, I now see, is 31.Rd8+!! What a shot!> Yes! I didn't even see the intervention on e6 and assumed it was mate next move.> I didn't anticipate 29...Qe8, but following ...      Sep-19-17 W So vs Ding Liren, 2017    patzer2: Here's another look at the missed win with 41. Rxb3! using Stockfish 8: 41.Rxb3 axb3 42.gxf6 Rh2+ 43.Kc3 gxf6 44.Rg8+ Kd7 45.Nb4 Ke7 46.Rc8 Kd7 47.Rb8 Ke7 48.Nc6+ Kd7 49.Nxa5 bxa5 50.Ra8 Rh1 51.Rxa5 Rd1 52.Ra8 Rf1 53.Kxb3 Rc1 54.Rf8 Ke7 55.Rg8 Kd7 56.Rh8 Ke7 57.Rh6 Rf1 58.Kc2 Rf2+ ...      Sep-19-17 Van Wely vs D Garcia Ilundain, 1993   patzer2: White missed a win by snatching a pawn too quickly with 28. Qxf7+? Kh8 ⩲ to ± (+0.63 @ 34 depth, Stockfish 8.) Instead, 28. Rf1! +- (+3.81 @ 27 depth, Stockfish 8) is winning easily for White.      Sep-19-17 C F Morris vs D Garcia Ilundain, 1997    patzer2: Another excellent game by GM David Illundain was his Benko Gambit win as Black in Van Wely vs D Garcia Ilundain, 1993 .      Sep-19-17 Aronian vs Ivanchuk, 2017    patzer2: <Chesshighercat> <totally pathetic> No I never said you advocated using game analysis alone to determine cheating. I simply summarized your position in your own words as a <system of analysis and investigation,> and after your reply I acknowledged that you meant ...      Sep-18-17 V P Normantas vs V Vepkhvishvili, 1987    patzer2: While 17...Nh6 ⩱ holds for black, the alternative 17...Nf6?? (diagram below) [DIAGRAM] loses decisive material after 18. Rxf6! gxf6 19. Qh5 f5 20. Qg5+ Kh8 21. Qf6+ Kg8 22. Re1 Be6 23. Re3 Qd6 24. Qg5+ Kh8 25. Rg3 Qxg3 26. Qxg3 +- (+6.64 @ 29 depth, Stockfish 8.)      Sep-17-17 F Zita vs Taimanov, 1950    patzer2: For a White improvement, instead of the natural looking 18. Bg2? allowing 18...Ng4! ∓ (-0.90 @ 32 depth,) Stockfish 8 recommends the odd looking 18. Kg2! = to ⩲ (+0.23 @ 32 depth.)      Sep-16-17 A Montalvo vs Blatny, 1997    patzer2: For today's Saturday puzzle, I got as far as 19...Rc2 20. Bxd7+ Kd8 (not 20...Kxd7?? 21. Qxc2 +-,) and after 21. Qa3 (diagram below) [DIAGRAM] I didn't see anything wrong there (diagram above) with 21...Kxd7 -+ (-3.62 @ 32 depth, Stockfish 8.) Apparently, there's absolutely nothing ...
