Member since May-20-03 · Last seen May-25-17
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.

   May-25-17 Kasparov vs Bacrot, 2004 (replies)
 
patzer2: Even World champions can miss elementary table base endgame wins, as evidenced by the missed opportunity 66. Kd4? allowing 66...Kh5 = draw in today's Thursday (66. ?) puzzle. Instead, as the game notes indicate, 66. Kf3! is ...

patzer2: For the benefit of novices like my six-year-old Grandson, if 28...Qf6 (diagram below) [DIAGRAM] White wins with 29. g4+ [DIAGRAM] 29...Kxg4 30. Qxf6 winning the Queen with mate soon to follow. P.S.: My eight-year-old ...

patzer2: Since it was a Tuesday puzzle, I knew from past experience to look for Queen sacs and quick mates. As a result, I quickly found 26. Qg6! forcing mate in one, two or three moves. Black's loss was due to the not-so-obvious error <21...Kf8?,> allowing the surprise winning move ...
 
   May-22-17 A Khudaya vs Yifan Hou, 2007 (replies)
 
patzer2: What I like about this game is how Black baits a trap with 20...h4!?, and how White falls into the trap with 21. h4? Nxh4! 22. Kxh4? Nxf3+ with mate to follow on ...
 
   May-21-17 Svidler vs Mamedyarov, 2017
 
patzer2: Running Stockfish 8 for over six hours to 40 depth yields 15. Be3 (+1.23 @ 40 depth) and 15. h4 ( +0.93 @ 40 depth.) Looks like 15. Be3
 
   May-21-17 Ilyin-Zhenevsky vs F Bohatirchuk, 1924 (replies)
 
patzer2: In the follow-up Stockfish 8 gives 47...Bc5! (-7.39 @ 33 depth) as stronger than 47...Kb6 (-5.14 @ 32 depth.) I prefer 47...Bc5! (diagram below) [DIAGRAM] over ...
 
   May-20-17 D Berczes vs G Kursuz, 2007 (replies)
 
patzer2: I was curious as to why 18...Rc8 is so good and 19...Rc8? is so bad. So I plugged it into Stockfish 8 and soon realized the strong 18...Rc8 works because 19. dxe5? now fails due to the unobstructed Bishop on g7. After ...
 
   May-19-17 Grischuk vs B Grachev, 2017 (replies)
 
patzer2: I was curious to see what the best Stockfish 8 line was for White after <34. Rb5!> 34...axb5, so I played it out to at least 30 depth per move with the following result: Following <34. Rb5!>, if 34...axb5 White wins after 35.Rxb1 Rb7 36.cxb5 Qe6 ( 36...Qb6 37.e5 Re7 ...

patzer2: White's game takes a turn for the worse with the awkward 25. Nab2? to , potentially allowing an immediate 25...Nxe3
 
   May-17-17 D Arutinian vs B Laurent, 2007 (replies)
 
patzer2: I was suspicious that Stockfish 8 had not really found a win for White after the improvement 31...R3f4 32. f3! despite a near plus three evaluation at 38 depth. So I ran the program for over 6 hours on 31...Ref4 32. f3! to 42 depth and it came up with the following best play line ...
