What is your unpopular chess opinion?
And in fact Trappy Beowulf, which attempts to set traps in the hopes that its human opponents will fall victim to them, already slightly outperforms normal Beowulf. I have also since been made aware of Polecat, an engine trained to play trappily against humans. So I don't think it's unreasonable to suggest that in some situations, playing an objectively-worse move can yield better results.

How close are we to perfect chess strategy?
Au contraire! Polecat and Trappy Beowulf exist; the latter actually managed to get a higher rating on ICC than normal Beowulf did, when playing against human players.

Does a chess engine exists that makes mistakes, but ultimately those mistakes force a single unnatural human moves from the opponent? IE: Retreat back 1 square, pin queen to king. move piece to a multi-defended square, sack the exchange, move piece on the other side of the board, etc.
I'm aware of an engine called Polecat, which plays in such a way so as to provoke blunders from human players; it uses Maia to predict what sorts of blunders humans are likely to play.

Ooh, very nice. Looks like the authors of that paper made a modified version of the Beowulf engine.

Are there any bots that use psychology to try to get an edge against human players?
