Downswing
An extended losing stretch caused by variance even with good play.
In depth
A downswing is an extended losing period caused by variance, occurring even when a player makes correct, long-term profitable decisions. It reflects natural short-term fluctuations where outcomes deviate negatively from expected value, independent of skill or strategy errors. This phenomenon is a statistical inevitability in poker and contrasts with losses stemming from poor play.
