patzer2 Member since May-20-03 · Last seen Jul-21-17 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.

Jul-21-17 Nisipeanu vs M Bluebaum, 2017   patzer2: After 56...Rxg7 57. Kxg7 Kb3 = it's a tablebase draw. Knowing this Rook and Pawn endgame pays off for Black in this game.      Jul-21-17 J Perlis vs J Mieses, 1907   patzer2: Correction: For a <White> improvement, instead of 19. g3?!, allowing 19...B35 , the first player can keep it about level with 19. Qg1...      Jul-20-17 Nakamura vs R Bellin, 2016    patzer2: Out of curiosity, I plugged the Stockfish 8 improvement 13...Bh5 in for a long and deep move-by-move analysis with the following draw result: 13...Bh5 14.Nb1 Bg6 15.Qe2 Bh5 16.Qd3 Bg6 17.Nfd2 Nb8 18.Nc3 Nxc3 19.Qxc3 c6 20.Nf3 Bh5 21.Ne5 Nd7 22.Nd3 a4 23.Rfe1 axb3 24.Qxb3 Nb6 25.cxd5      Jul-20-17 A Gavrilov vs B Grachev, 2007   patzer2: I missed the neat 35...Nd2! obstruction tactic solution to today's Wednesday puzzle, which after 36. Bxd2 leads to mate-in-six with 36...Qxf2+ . Instead of 35...Nd2!, ...      Jul-18-17 Borbely vs Kovacs, 1948    patzer2: The Checkhover (B53) opening played here is an interesting option for White players looking to get Sicilian players off the beaten track and out of their opening book. 84-year-old GM Evgeni Vasiukov has had good success with it, even as recently as last year. Two notable victories ...      Jul-18-17 Vasiukov vs Browne, 1970    patzer2: White's 21. Qh7!! is a stunning Queen positional sacrifice that might make for an interesting Sunday puzzle. It's not a forced win, but it gives White a slight advantage and is better than the alternatives which give Black a big advantage.      Jul-18-17 Q Ducarmon vs N Zwirs, 2017   patzer2: Black's 14...b5!? 15. e5 worked out OK in this game due to a big White mistake. More prudent might be 14...h6 =.      Jul-18-17 Wei Yi vs Yu Yangyi, 2017   patzer2: After looking at the chessbase.com analysis, it's now apparent to me that the computer choice 22. Bxf5! to is much stronger than the game continuation 22. Rh5!?      Jul-17-17 R Rapport vs D Anton Guijarro, 2016   patzer2: Here's a deep move-by-move look at Sunday's 28...Nb6!! solution with Stockfish 8 (copy and paste to the Stockfish 8 engine for further analysis): [Event "Tradewise Gibraltar"] [Site "Catalan Bay GIB"] [Date "2016.01.26"] [Round "7.4"] [White "Richard Rapport"] [Black ...      Jul-17-17 Flohr vs Bogoljubov, 1931    patzer2: Took me a few minutes to find 40...R8g3 and solve today's Monday puzzle, because I was trying to calculate the variations following every check and capture first. White's decisive mistake was 37. Bxf3? allowing 37...exf3
