Cutoff (CO) (CO)

Also known as: Cutoff, CO

The seat directly to the right of the button — the second-best position. It opens and steals very wide, beaten only by the button itself.

The cutoff (CO) is the seat immediately to the right of the button. It is the second-best position at the table: only the button has position on you postflop, and only the button and blinds remain to act preflop.

That near-positional dominance makes the CO a premier stealing seat:

• Wide RFI: you open a large share of hands (roughly the top ~25–30% in 6-max), because only three players can contest and you'll often play the pot in position.
• High steal frequency: with the blinds just behind, raising to win the dead money outright is a core profit source.

The one caveat is the button. When the CO opens, the button can call to play in position or 3-bet to seize position, so your CO range must be robust enough to handle button aggression — you can't open quite as wide as the button itself. Against tight blinds and a passive button, though, the CO is one of the most profitable seats to attack from. Think of it as the button's slightly-less-powerful twin.
