I often see players using a "blunder check" or "accuracy score" after each move. It shows their move's evaluation, how exactly does chess.cmo generate this feedback so quickly during a game, especially in blitz and bullet formats. I know engines play a part but I'm interested in how they manage to do it so swiftly while keeping everything seemless fo rplayers. I'm asking about the behind the scenes process fo rthat?
If you mean the bars by the moves those are timestamps; how long it took to make the movess
If you mean the evaluation bar, that's only running for the spectators and is the engine running client side. It can get a few ply deep pretty quickly.
