I live in the Portland, OR area and play chess badly. Make that very badly.

   Apr-25-18 Akobian vs S Shankland, 2018
pdxjjb: Why 30 Qe4? After 30. R5c2 Qxa3 31. Qxa3 Rxa3 White stands better than in the actual game. R5c2 is pretty obvious?
   Apr-22-18 I Rogers vs V Arapovic, 1985 (replies)
pdxjjb: No hope for me to get this one. The computer has to get to like 17 ply before its analysis shows how much trouble white is in. Amazing job by Rodgers to find this over the board. Wow.
   Apr-21-18 Gashimov Memorial (2018) (replies)
pdxjjb: Two days without a decision. Organizers should cancel, send everyone home. No prizes to be awarded. ;-)
   Apr-21-18 B Kreiman vs L Christiansen, 2002 (replies)
pdxjjb: Before the puzzle position, white misses the very strong 33 bxa4. A line involving a similar looking sham sacrifice leaves the surviving black rook unable to stop the a-pawn. (Found by engine.)
   Apr-18-18 Svidler vs Kramnik, 1999 (replies)
pdxjjb: When I saw the possibility of a Q sac, I had a sinking feeling ("c'mon, man, this stuff never works in my games.") ;-)
   Apr-15-18 Lasker vs J Bauer, 1889
pdxjjb: Analyzing this with a modern engine is interesting. First, if you watch closely, the engine thinks 13 ... a6 is a pretty reasonable move out to 20 ply search depth or so; only when the search gets very deep does the engine decide it's not such a good idea. Second, the engine thinks ...
   Apr-09-18 Vitiugov vs Caruana, 2018 (replies)
pdxjjb: SF9 holds the game still pretty equal after 25 ... Qe7. 26 Ng5 is a weak move. The engine thinks NV's best hope for recovery is to say "oops" and move the night back where it came from. The actual move 26 Nf3 leads into complications that NV never really recovers from.
   Apr-07-18 M Bluebaum vs Anand, 2018 (replies)
pdxjjb: Was 19 ... Bd5 a sac or an oversight?
   Apr-06-18 E Inarkiev vs D Temirkanov, 2012 (replies)
pdxjjb: After having a shot at this one, you should analyze it with an engine. The results are amusing.
   Apr-03-18 AlphaZero vs Stockfish, 2017 (replies)
pdxjjb: <ChessHigherCat> Back on the machine learning thing, I don't think the truth is quite as optimistic as the way you played it back. In practice, the machine won't just continue to improve, and in some cases it will get worse if you overtrain it (search the term "overfitting" if ...
