I like to say that after my chess teacher — who doesn’t like anything I do, and assigns homework — the 2nd-biggest buzzkill in chess is Stockfish, who merely doesn’t like anything I do. Modern chessplayers have grown accustomed to the feeling that they’ve done something right at the chessboard, only to have Fritz or Hiarcs say: Nope, you screwed up here. And here. And here. And also here.
