patzer2
Member since May-20-03 · Last seen Apr-25-18
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.

   Apr-25-18 P Tregubov vs Efimenko, 2008 (replies)
 
patzer2: Black's game takes a turn for the worse with 17...Ng4?, allowing 18. Qd3 to +- (+1.75 @ 34 ply, Stockfish 9 analysis of move 18.? ). Instead, 17...Rfc8 18. Qe2 ⩲ (+0.30 @ 31 ply, Stockfish 9 analysis of move 17...? ) appears to give Black a better fighting chance of ...
 
   Apr-24-18 M Kobalia vs D Andreikin, 2018
 
patzer2: <WorstPlayerEver> After 32...Qxa3 33. Qe1, Stockfish 8 gives 33...Nb4! = (0.00 @ 33 ply) as it's a draw by perpetual check after 32...Qa3 33.Qe1 Nb4 34.cxb4 c3 35.Qc1 Qxb4+ 36.Ka2 Rh1 37.Rg1 Rxg1 38.Nxg1 Qc4+ 39.Kb1 Kxd7 40.Nf3 Qb5+ 41.Ka2 Qc4+ 42.Kb1 =.

patzer2: Found the first two moves 36. hxg6 Rxh1 37. g7 +- (+8.46 @ 27 ply, Stockfish 8) for today's Tuesday puzzle solution and game continuation without much difficulty. Yet after 36. hxg6, I found the potential reply 36...Rg8 challenging. My planned response was 37.gxf7 Kxf7 38. Kf4 +-. ...

patzer2: For an early White improvement, the apparently untested computer suggestion 8. e5 ⩲ to ± (+0.72 @ 22 ply, Stockfish 9 analysis of move 8.? ) looks good.
 
   Apr-22-18 I Rogers vs V Arapovic, 1985 (replies)
 
patzer2: For an improvement for the losing side, I'd start early in the opening and look to do better with 4...e5 = to ⩲ (+0.25 @ 31 ply, Stockfish 8) as in Black's win in N Brunner vs Fressinet, 2012 .
 
   Apr-21-18 B Kreiman vs L Christiansen, 2002 (replies)
 
patzer2: I assume White pointed out <FSR>'s drawing line <37.Qg1! Rxb4 38.Qa7! Rb1+ 39.Kg2 a1=Q 40.Qxf7+ with a perpetual check> when he offered the draw after 37. Qg1! The alternative 37. Qd1?? loses to 37...Rxb4 -+ (-52.55 @ 31 ply, Stockfish 9 analysis of move 37...? ).

patzer2: Also, instead of 17...gxf4? allowing 18. e4! ± (+0.84 @ 30 ply, Stockfish 8), Black would have been better off getting the King to safety and preparing a solid defense with 17...0-0-0 18. e4 Bc7 19. e5 Qg7 20. Bf5+ Bxf5 21. Qxf5+ Kb8 = (+0.14 @ 32 ply, Stockfish 8).
 
   Apr-19-18 S Gupta vs F Grafl, 2016 (replies)
 
patzer2: For a Black improvement, I'd start early and ditch 2...Nf6 3. e5 Ng4 4. d4 ± (+0.97 @ 27 ply, Stockfish 8) in favor of 2...e5 = to ⩲ (+0.22 @ 27 ply, Stockfish 8).
 
   Apr-18-18 Svidler vs Kramnik, 1999 (replies)
 
patzer2: The computer indicates Black can improve over the logical human move 13...e5 =, played in this game and in Thanh Son Nguyen vs Harikrishna, 2001 , with the apparently untested (at least according to our Opening Explorer) 13...d5 ⩱ (-0.27 @ 29 ply, Stockfish 9 analysis of move
 
   Apr-17-18 Caruana vs T Petrik, 2006 (replies)
 
patzer2: <sfm: 34.Rd5 was not it, but what should White have played (apart from "everything else")?> White was busted after 30. R(a)d1? (should have played 30. Qe4 =), allowing 30...Rf4! -+. By the time it came around to move 34, White had no chance. One amusing alternative is 34. Qd5 ...
