Sudden Death - Improve TM Due to the 50 estimated move horizon, once a sudden death game got below 1 second, the time allocation for optimumTime would go into the negative and SF would start instamoving. To counter this, once limits.time is below 1 second, the move horizon will start decreasing, at a rate of 1 move per 20ms. This was just what seemed a reasonable rate of decay.
