Offsuit means your two hole cards are different suits, written like AKo. The hand can't make a flush together, so most offsuit holdings play a step weaker than their suited cous...
Omaha (Omaha Hold'em)
Omaha is the four-hole-card poker variant family that uses Hold'em's community-card framework with one strict twist: every showdown hand must use exactly two of your four hole c...
One-and-Done

Open-Ended Straight Draw
An OESD is a straight draw with 8 outs — about 17% to hit on the next card and 31.5% by the river. Either end of the four connected cards completes the straight.
Open-Limp
An open-limp is a limp made when you are first into the pot preflop, calling the big blind instead of raising or folding. The limp action itself just means matching the big blin...
Open-Raise
An open-raise is the first voluntary pre-flop raise after the blinds are posted. It builds the pot, seizes initiative, and shapes how many opponents you face.

An "out" is any unseen card that will likely make your hand a winner. In No-Limit Texas Hold'em unseen cards are those remaining in the 52-card deck. Outs drive draw decisions b...
Overbet

Overcard
A card ranked higher than the card or pair you compare it to — either a hole card above the board or a board card above your pocket pair.

Overcards are your hole cards that rank higher than every community card on the board. For example, A-K or Q-J on a 7-4-2 flop are both overcards to the board. Overcards can app...
Overfold

Overpair
An overpair is a pocket pair higher than every card on the flop, the first three community cards. For example, Q♥Q♦ on a 7♣-6♣-2♦ flop is an overpair to the board. If the flop c...
