Coin flip
An all-in between two hands of roughly equal winning chances.
In depth
In poker, a coin flip refers to an all-in situation where two hands have approximately equal chances of winning. This scenario occurs when neither player holds a significant advantage, resulting in a near 50-50 equity split. The term highlights the high-variance nature of such confrontations, commonly seen in tournament play when players commit their stacks with marginal edges.
