Does clearing hash after every move reduce engine strength? #71

Closed yjf2002ghty closed 2 months ago

yjf2002ghty commented 2 months ago

I am reviewing the code written before and noticed that currently the UI sends a clear hash command to in browser fairy-stockfish after every move. Does this reduce engine strength? If yes, I'll create a pull request to fix this.

This does not affect binary engines.

Yes, it does. Clearing hash should happen when hash entries become irrelevant, e.g., when changing the variant or setting up a completely new position, but after merely making a move hash will still be highly relevant and beneficial.

OK, I'll fix this.
