Remove SlowMover Option The SlowMover option allows users to modify the timeLeft variant, impacting the engine's time management. However, this feature, while theoretically flexible, doesn't offer substantial benefits. Instead, it introduces the risk of non-experienced users altering values without a clear understanding of the effects, potentially leading to a weaker engine. The vast majority of SF users don't use it anyway, and based on tests conducted by fauzi several months ago suggest that changing it would only lose Elo.
