To chase is to play a draw hoping to complete it despite odds against you.
Explanation. The term comes from “chasing” the right card—continuing in a hand because you hope a draw will hit. For example, calling a turn to chase a straight or flush on the river. It often reflects psychological bias: players may chase hoping to avoid “throwing away” the pot. Beginners should understand pot odds vs chase probability; selectively chasing is key to avoiding poor long‑term results.
