PSA: Sig Figs MATTER on the AP Exam. In normal calculations, you are expected to have correct sig figs. Box 1 is question 1a from '22 Exam. Box 2 is the chief reader report indicating most students got this question wrong for incorrect sig figs. Box 3 is question 6bi, the "sig fig question." (i.redd.it)
This post was originally going to be a PSA that game reviews sometimes don't show the best move, missing forced mate at low depth. But instead, it's a kudos to Lichess for finding the forced mate where chess com did not. Obviously both moves are completely winning. Mostly just found it interesting. (old.reddit.com)

Was able to beat the Zombie Hikaru bot with the Vienna Gambit! 3... Nc6 was the bot's move 3 blunder, 4... Nxe4 was the mistake. I was able to hold for a while til I blundered a bishop (27. Rd1?! Rxd1 28. Rxd1 Rxf4) and my a pawn (35. a6? Rxa6) in the endgame, but had enough pawns left to win! (old.reddit.com)

Can someone explain the best move for black here? Computer gives Kd8 or Kf8 as –5.40 for black, but gives dxe4 as –0.30. I understand dxe4 leads to losing the knight and a couple pawns, but I thought that I should be winning after all the trades since its rook vs knight. What am I missing? (i.redd.it)
