The strongest hand still loses when impatience plays it badly.

Having the better position guarantees nothing about the outcome. Impatience spends advantages early, forces situations that would have resolved on their own, and converts a strong hand into an ordinary one through nothing but poor timing. Most losses from good positions are self-inflicted in exactly this way. The advantage was real; the handling was not.

When you are clearly in the stronger position, slow down rather than pressing. Ask what waiting costs you, and if the answer is very little, wait. Good positions are usually lost by acting too soon rather than too late.
