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.

   Jun-25-17 Keres vs E Walther, 1964
patzer2: I let the position after 23...Bg6 run for over 10 hours on Stockfish 8 to 48 depth with the following result: [Stockfish 8 64] 48:+3.72] 24.Nxg4 hxg4 25.Rxf8+ Bxf8 26.Qxg4 Kh7 27.h5 Bd3 28.Rf3 Qc8 29.Qg5 Bc2 30.Qd2 Qg4 31.Qxc2+ Kg8 32.Qf5 Qxf5 33.Rxf5 Rc8 34.Kh2 b5 35.g4 Rc4 36.Rg5+
   Jun-24-17 Caruana vs Eljanov, 2016 (replies)
patzer2: I let Stockfish 8 run for over six hours to 49 depth analyzing the computer best play line 32. e6+! Bf6 33. Qf4! Bg5 (diagram below) [DIAGRAM] Here (diagram above after 33...Bg5 34.Qxf7) Stockfish 8 gives 34.Qxf7 gxh5 35.Qxh5 Be8 36.Qe2 Qg7 37.Nf5 Qc3 38.e7 Bh5 39.Qe5+ Qxe5 40.Rxe5 ...
   Jun-23-17 Mamedyarov vs Van Wely, 2016 (replies)
patzer2: With help from telling me there was a Friday puzzle solution for Black's 17th move, I found the missed winning move 17...Ng5! . Stockfish 8 give the following winning line: 17...♘g4! 18.♕e1 If ...
   Jun-22-17 A Adly vs I Vovk, 2007 (replies)
patzer2: For today's Thursday solution, 36. Rg8+ forces mate. For an early improvement, Stockfish 8 suggests ditching 17...Nfd7?! and replacing it with 17...Ncd7 = (0.00 @ 34 depth.)
   Jun-22-17 M Pantzar vs T Rodshtein, 2016 (replies)
patzer2: As <gofer>'s post suggests, White's decisive mistake was 21...exf5? allowing today's Wednesday puzzle solution 22...Bc6+! 22. Be4 Qg6! (-2.46 @ 20 depth, Deep Fritz 15.) Instead, <gofer>'s suggestion 21. Rxf5! ...
   Jun-18-17 Zsofia Polgar vs A Chernin, 1989 (replies)
patzer2: <SirChrisLove> Thanks for the link to the excellent annotation of this game by the game winniner Zsofia Polgar. I'll ask my 8-year-old grandson who now has a near 2100 tactical rating on, but sometimes struggles with positional play, to take a look at her notes. Her ...
   Jun-04-17 Shirov vs Lautier, 1995 (replies)
patzer2: Would have played 27...Bxh4! in blitz, so I had no problem picking it for today's Sunday puzzle solution. The obvious idea is to overload attackers on h3 after 28. gxh4 Nf4+ .
   Jun-03-17 Kupreichik vs C Morrison, 2003 (replies)
patzer2: Easily found the demolition sacrifice 23. gxf6! for my Saturday puzzle solution. However, the follow-up 23...Qxg6 24. Be5! was a bit more difficult.
   Jun-01-17 P L Basso vs A Korobov, 2017 (replies)
patzer2: <Iwere Sonsch> Thanks for correcting my typo on 32...Rxb2 in the 31. c6! Nf6 32. Qxa6 Rxb2 33. c7 Qxe5 34. c8(Q)+ (+6.20 @ 29 depth, Stockfish 8) winning line. P.S.: <Devere>'s post shows the same winning idea also works after 31. c6! Bf6 32.Qxa6 Rxb2 33.c7 Qxe5 34.c8=Q+
   Jun-01-17 Ivanchuk vs S Shankland, 2017 (replies)
patzer2: <An Englishman> Yes, I did get the wrong move number on the improvement for 32...Rb8? 33. Nce5! to (+1.66 @ 28 depth, Stockfish 8). Instead of 32...Rb8?, Black ...
