Member since May-20-03 · Last seen Jan-17-18
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: In attempting to solve today's Wednesday puzzle, I first looked at 23...Rxa5!! 24. Qxa5 Re2+ 25. Kf1 (25.Kg1 Qd4+ 26. Kf1 Qf2#) 25...Ba3! -+. But then I decided to look for an alternative win where I didn't have to sacrifice of the exchange. That's when I saw the tempting but flawed

patzer2: Correction: I picked 37...Nh4 -+ instead of 37...d4 -+.

patzer2: For today's Monday puzzle (33. ?), 33. Rxe7+ Kxe7 34. Nf5+ +- is an obvious winning knight fork. What's not so obvious is the forced mate after 34...Ke8 35. Nxd6+ +- (mate-in-17, Stockfish 8 @ 26 ply). P.S.: Black's decisive error was 30...Ke8? allowing 31. Qg8+ +- (mate-in-30, ...

patzer2: White's game takes a turn for the worse with 26...Rxc3 27. Qxb3 ± to +- (+1.67 @ 33 ply, Stockfish 8). Instead, 26...Rd6 27. Bf4 Rd7 28. Nf3 ⩲ to = (+0.22 @ 36 ply, Stockfish 8) gives Black a fighting chance.

patzer2: Since Black is up a whole Rook and it's a Sunday puzzle (26...?), I figured the first move had to be the demolition of pawn structure sham sacrifice 26...Rxb2!! 27. Kxb2 (not 27. Nxd7? Rd2+ -+) Rb8+. At a glance, White's position doesn't look so terribly bad after 27...Rb8+ 28. Nc3 ...

patzer2: <diagonalley: ok, but even if you get the first move, the continuation/s seem damn near impenetrable. <diagonalley>: nul points :-(> The best play game continuation 21...dxc3 -+ (-6.17 @ 32 ply, Stockfish 8) is a line I also found difficult. Much easier for me to ...

patzer2: For today's Friday puzzle (29...?), I missed Black's brilliant combination 29...Nxe5!! (only winning move) 30. fxe5 h4+! (only winning move) 31. Kf2 Qxe5+ 32. Bf4 Rb2! (only winning move) -+ (-6.10 @ 38 ply, Stockfish 8). My failed try was the simple 29...Nxe3 which gives Black a ...

patzer2: After the alternative winning line 25. Nh6+ Kg8 26. Qe6 +- (diagram below) [DIAGRAM] If 26...Ng7, White has a pretty smothered mate with 27. Qg8+ Rxg8 28. Nf7# (diagram below) [DIAGRAM]
 
   Jan-11-18 Bu Xiangzhi vs Minghui Xu, 2017
 
patzer2: Instead of 50...Qd7+ 51. Ke5 ∓ (-1.21 @ 30 ply, Stockfish 8), Black would still have retained winning chances with the forcing line 50...Ne7! 51. Ke5 bxc5 52. Ne3 a4 -+ (-4.17 @ 29 ply, Stockfish 8).
 
   Jan-10-18 B Kostic vs D Avirovic, 1945 (replies)
 
patzer2: For today's Wednesday puzzle (28. ?), I found 28. Ng5! which threatens 29. Qh7# and overloads two of Black's defending pieces. The Bishop is overloaded because it can't simultaneously defend against 28...Bxg5? 29. Qg7# and the 28...Nxg5 29. exf6 +- game continuation. The Knight is ...
