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.

patzer2: I tried to make something work in attempting today's Saturday puzzle (25...?), but I finally gave up and looked at the answer. After playing through this impressive game with the solution 25...Rd8!! -+ (-4.41 @ 35 ply, Stockfish 9 analysis of move 26...? ), and reading ...

   Jun-15-18 Nakamura vs W So, 2018
patzer2: An analysis of this game at concludes <Somehow Nakamura must have been confused in the opening, a London System, because it was basically his seventh move that sealed his fate. It's rare thing to see him looking at a technically lost ...

patzer2: The strongest solution to today's Friday puzzle is 18. Rxd7+! +- (18.31 @ 29 ply, Stockfish 9 analysis of move 18.? ) with a crushing King hunt. My attempt 18. g5 +- (+2.80 @ 29 ply) is only the third best move. P.S.: Black's decisive mistake was the pawn grab 16. Qxf4+? 17. Kb1 +- ...

   Jun-14-18 Caruana vs W So, 2018
patzer2: <Richad Taylor> Thanks. Your comment about 29. exd5?! is concise and insightful. No doubt 29. Rxe5= would have greatly improved White's chances of securing the draw.

patzer2: <Jimfromprovidence: Side puzzle. If black's h rook is on h8 instead of h7, does 33 Rxb8+ still work?> Yes it does. The moves 33. Rb2 Rhh8 34. Rxb8 +- (+5.20 @ 24 ply, Stockfish 9 analysis of move 34...? ) transpose to 33. Rxb8 +- in your puzzle position (i.e. with the h Rook ...

patzer2: After Black's mistake with 31...Ne4?, White misses a win with 36. b4 (+1.33 @ 32 ply, Stockfish 9 analysis of move 36...?). Instead, 36. Bd1 +- (+2.23 @ 31 ply, Stockfish 9 analysis of move 36.? ) wins by threatening to trap one of the Black Rooks on the second rank, which gives ...
