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

   Apr-14-23 Nepomniachtchi - Ding World Championship Match (2023) (replies)
pdxjjb: Game 4: if Nepo dispenses with the knight's tour and plays 25 ... Bg6, DL has nothing.
   Apr-06-23 Wei Yi vs V Malakhov, 2023 (replies)
pdxjjb: I can't imagine why Malakov would play 13 ... c5. It's probably not even one of his 10 best choices. Did he touch the pawn by accident?

pdxjjb: I think this "1.5 star" puzzle was much easier than Monday's "1 star" puzzle.
   Feb-01-21 K Burger vs C Lyon, 1952 (replies)
pdxjjb: I also found Rh4. It's longer only because it gives black the chance for two spectacularly pointless sacrifices (32. Rh4 Qxg2+ 33. Kxg2 Rxg3+ 34. hxg3 black any and then mate.)
   Jan-28-21 A Donchenko vs Caruana, 2021
pdxjjb: <perfidious> Stockfish recommends 15 dxc5 rather than d5. If you follow that with the chess engine, it looks more like the boring draw we all expect from a QGD between GMs. An example is 15. dxc5 Nxc5 16. h4 Rc8 17. Kb1 Na4 18. Qd3 Qxd3+ 19. Bxd3 Rd8 20. Be2 Nxc3+ 21. Bxc3 ...

pdxjjb: Why is this puzzle a 2? I am not very good at puzzles, and I solved it in about 15 seconds.
   Jun-25-20 P Acs vs J Konnyu, 2017 (replies)
pdxjjb: Really nice puzzle. I failed to visualize the effect of White opening the f-file with 25 fxe3. Engine confirms (as others have observed) that 26...Qe7 is a mistake. With proper play by Black, e.g. 26...Rc7, White can "only" win the Exchange, leaving Black with some compensation in ...

pdxjjb: <TheTamale>: exactly. An "easy" puzzle that was actually easy. I needed this.
   Jan-01-20 Flohr vs I Koenig, 1929
pdxjjb: On my late-model Mac, Stockfish took 20 seconds to give up on Qxc5 and get the right answer. To me that says something about how surprising the correct answer is.

pdxjjb: Carlsen was about 90 ELO better than MVL before these games. And the last I looked, he was a pretty tough competitor. So are all the naysayers here accusing Carlsen of not trying, or accusing MVL of some kind of misconduct because he succeeded in drawing twice despite a 90 ELO gap? I
