Member since May-20-03 · Last seen Dec-15-17
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.

   Dec-15-17 Kasparov vs Lautier, 1994
 
patzer2: Didn't immediately recall today's Friday puzzle (28. ?) from 12 years ago, but perhaps I had a faint recollection as I managed to find 28. Ng4! +-. The computer indicates Black's decisive mistake was 25...Rc5? allowing 26. h6 +- (+3.66 @ 27 ply, Stockfish 8). Instead, 25...Rg8 26. ...

patzer2: Black's best missed chance appears to be 28...Ra8 ∓, when play might go 28...Ra8 29.Rc1 Qa7 30.dxe4 fxe4 31.Re5 Qc7 32.Qc5 d3 33.exd3 exd3 34.Qc3 Rad8 35.Rd1 Ng4 36.Rxe6 Rxe6 37.Qc4 Re8 38.Bd5 Qf7 39.Bxe6 Qxe6 40.Qxe6+ Rxe6 41.Rxd3 Rxc6 42.Rd4 Ne5 43.Rd5 Rc1+ 44.Kg2 Nc6 45. ...
 
   Dec-13-17 Gulko vs Adams, 2000 (replies)
 
patzer2: <gofer> Stockfish 8 says it's mate-in-six after 37...Ne3+ which apparently makes it mate-in-seven counting the first move of the combination. One mate-in-seven line goes 37...Ne3+ 38.fxe3 Rb2+ 39.Kh3 Qxf3 40.d5 (diagram below), [DIAGRAM] 40...Qf5+! (not 40...Rb1? 41.Qc8+ Kh7 ...
 
   Dec-12-17 Carlsen vs I Nepomniachtchi, 2017 (replies)
 
patzer2: <visayanbraindoctor> Enjoyed your post analyzing Carlsen's playing style. I tend to agree with 1., 2. and 3. of your observations. However, I'm not so sure about <4. Be materialistic as possible. No speculative sacrifices. Grab any material that looks grabbable and if the ...
 
   Dec-12-17 R J Dive vs P W Stuart, 1987 (replies)
 
patzer2: For today's Tuesday puzzle (29. ?) solution, White begins with the decoy 29. Rd7+! forcing 29...Qxd7. If Black doesn't resign, as in the game, then White will follow with 30. Rh7+! +- (mate-in-11, Stockfish 8 @ 53 ply). P.S.: According to Stockfish 8, Black's decisive mistake was ...
 
   Dec-11-17 Judit Polgar vs P Kerkhof, 1987 (replies)
 
patzer2: <stacase> If 30...Kh6, it's suddenly not such an easy Monday puzzle. Stockfish 8 gives the winning replies 31. Be6! +- (mate-in-nine), 31. Qd3 +- (+25.35 @ 27 ply) or 31. Qf3 +- (+19,06 @ 27 ply). What White must avoid is the tempting 30...Kh6 31. Qf6+ Qxf6 32. Bxf6 ⩲ ...
 
   Dec-10-17 E Vladimirov vs G Agzamov, 1977 (replies)
 
patzer2: In today's Sunday puzzle (29. ?), White is a pawn down but all of his pieces are strongly posted and attacking the weak, castled Black King position. Moreover, the Black Knight is out of play on the Queenside and the Black King is under protected. So an all out assault by White on ...
 
   Dec-09-17 Nakamura vs Carlsen, 2017 (replies)
 
patzer2: In deep computer hindsight, 59. Ra3! +- (+2.26 @ 39 ply, Stockfish 8) looks like a win: ( [Stockfish 8 64] 39:+2.26 59.Ra3 Kd5 60.Rf3 Ke6 61.Ke3 Kf6 62.Kd2 Rc4 63.Rg3 f4 64.Rf3 Kg5 65.Ne2 Re4 66.Nc3 Re1 67.Kxc2 Kg4 68.Kd3 Rg1 69.Rf2 Kg3 70.Ne4+ Kg4 71.Ke2 Ra1 72.Rf3 Ra2+ 73.Nd2 ...
 
   Dec-09-17 V Malakhov vs A H T dos Santos Fier, 2009 (replies)
 
patzer2: <Tolson61> After 41. Rg3!! Qd6, White wins with 42. Nxe4! +- (+12.08 @ 27 ply, Stockfish 8).
 
   Dec-08-17 Ding Liren vs E Inarkiev, 2015 (replies)
 
patzer2: Missed today's Friday (30. ?) puzzle, which cleverly combines the decoy/deflection tactic 30. Bc2! Qxc2, the obstruction tactic 31. Nd3! Kd8 and the discovered attack with check tactic 32. Qxh7+ Kf7 33. Ne5+ Ke6 34. Qxf2 +- to win the Queen for two minor pieces. P.S.: For an ...
