Mikhail Chigorin

Yeah, and good that you spot this.

I modeled this example in a famous game between Stein Aids and Chigorin.

The most painful single game in World Championship history.

Chigorin was down with one game, it's a penultimate round I guess.

If he won this game, then he could equalize the match, World Championship match.

Chigorin in a very similar position, he blundered.

in a way that his bishop was guarding the pawn on h2 in a very similar position he moved the bishop away from this diagonal somewhere like this and he allowed rook h2 followed by let's say rook g2 mate in a very similar position he didn't see the bishop moving from this diagonal was allowing those two rooks actually giving mate to his king

yeah
