patzer2
Member since May-20-03 · Last seen Aug-19-17
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.

patzer2: <morfishine> I try to be precise in my use of the Chess terms, such as "deflection." Using the definition at your wiki link, <Deflection in chess is a tactic that forces an opposing piece to leave the square, rank or file it occupies, thus exposing the king or a valuable ...

patzer2: Tough Friday puzzle position (32...?) for me, as it soon became clear the Black King was shut off from the protection of its pieces and would have to take a walk while trying to escape a King hunt and avoid mate. To make matters worse, there's no safe way to avoid the Black King ...

patzer2: For today's Thursday puzzle (24. ?) solution I went with 24. Ne7+, visualizing at least the win of the exchange after 24...Rxe7 25. Rxd8+ Nxd8 26. Rxd7 +- (+8.26 @ 30 depth, Stockfish 8) or a crushing attack after 24...Kf8 25. Rxd8 Nxd8 25. Qxc5 +- (+4.08 @ 30 depth, Stockfish 8.) I

patzer2: Caissia, the Goddess of Chess, can be a cruel and cavalier mistress. She almost seems to delight in the occasional discomfort of her past favorites, as she transfers her affections and gifts to younger, more ardent suitors.
 
   Aug-16-17 Aronian vs I Nepomniachtchi, 2017
 
patzer2: White's decisive error appears to be the desperation piece sacrifice 51. Bxc3? which allows 51...Bxc3 ∓ to -+ (-1.74 @ 42 depth, Stockfish 8.) Instead, 51. Kg2 = (0.00 @ 33 depth, Stockfish 8) holds as play might go 51.Kg2 Nxd4 52.Re4 c2 53.Bxb4 Rxb4 (not 53...c1=Q?? 54.Bf8+ ...

patzer2: <Marmot PFL> Thanks! Here's a few other side lines examining the strong winning f6 demolition <18. Nf6+! gxf6> 18...Bxf6 19.exf6 O-O 20.Bxd7 Qxd7 21.Rg3 g6 22.Kc1 f4 23.Qxf4 Kh8 24.Rh3 Qf5 25.Qh6 Qh5 26.Qg7#. <19.exf6 O-O> 19...h6 20.Qb4 Bxf6 21.Re1+ Be7 22.Rg3 ...

patzer2: White's 14. Rab1?! allows Black immediate equality with the strong positional pinning combination 14...Bxc4! = to ⩱ (-0.17 @ 30 depth, Stockfish 8.) Instead, 14. Na4 c5 15. Rad1 ⩲ (+0.40 @ 30 depth, Stockfish 8) appears to leave White with a slight edge.

patzer2: Instead of 33. Rh1? allowing 33...Qg5 ∓ (-1.10 @ 32 depth, Stockfish 8,) White can hold it level with 33. Rxe8 = (-0.03 @ 33 depth, Stockfish 8.)
 
   Aug-15-17 Oral vs S Brodbeck, 1997 (replies)
 
patzer2: <Coriolis> Silicon (Stockfish 8) likes 23. Nf7+ +- just fine, as it's mate-in-ten after 23.Nf7+ Nxf7 24.gxf7 c4 25.Rxh6+ Bxh6 26.Bc8 Qxa2+ 27.Kxa2 b3+ 28.Ka1 Re6 29.Qd8+ Bf8 30.Qxf8+ Kh7 31.Qg8+ Kh6 32.Rh1#. I much prefer mate-in-three with 23.Rxh6+ Bxh6 24.Qxe5+ Bg7 26. Rh1#,
 
   Aug-15-17 E Najer vs T L Petrosian, 2016
 
patzer2: Great positional attacking game by White. However, Stockfish 8 indicates Black's 13...Nd7?! allows White a clear advantage after 14. d4 Nce5 15. Nc1 ± (+0.62 @ 25 depth.) Instead, Black can apparently hold it level with 13...Nh5 = (+0.00 @ 30 depth, Stockfish 8) when the ...
