Air refers to a hand with little or no value, often used in bluffing.
Explanation. “Air” is poker slang for a hand that has no pair, no draw and minimal chance to improve—e.g. 7‑2 off‑suit or hands that “miss” the flop entirely. Betting with air means bluffing despite holding nothing. Skilled players use air to represent stronger hands, but beginners should only bluff carefully. The term is common in both cash and tournament play.
