Essentially, do Chess Engines acknowledge that their opponents might make "flawed" moves? Or do they always assume absolutely perfect play.
More specifically, if an engine has a choice between 2 moves and one of them is:
- Mate in 5, with perfect play, all of which is completely obvious
and the other is
- Mate in 4 ... but only if the opponent does something superficially counter-intuitive. And if they do the superficially obvious thing then you can actually escape the Mating sequence into a not-directly Mated position
If you assume perfect play, then both positions are a loss, and I assume that engines are "taught" to pick the longest game if all games are lost.
But I would argue that if you believe the game is lost either way, you might want to pick the line with highest chance of an error, instead?
Do engines do that?
