Study future community cards
Select the known cards, the rank you want to track and the number of community cards still to come. The calculation measures how often that rank appears among those future cards.
A scare card describes a change in board texture, not an automatic losing card. Combine the probability with the actual hands or ranges you are studying.
Is scare-card probability the same as poker equity?
No. It measures the occurrence of a chosen rank, not your chance of winning the hand.
