Use 5% less time on first move Stockfish appears to take too much time on the first move of a game and then not enough on moves 2,3,4... Probably caused by most of the factors that increase time usually applying on the first move. Attempts to give more time to the subsequent moves have not worked so far, but this change to simply reduce first move time by 5% worked.
