When analyzing a game with Stockfish I sometimes find it confusing that evaluation of a given position changes depending on what positions I had analyzed previously. I understand that this is because the engine reuses its hash table contents. I'd rather have potentially weaker analysis but consistency.

Stockfish offers the Clear Hash UCI option which shows up as a button in the "configure engine" GUI of Arena.

Is there a way I can automatically clear the hash table whenever I switch positions?
