The Cutoff Opens and You Are on the Button. What Now?
A friendly guide to calling and 3-betting on the button against a cutoff open, including what the blinds change.
The cutoff raises and you are on the button with a hand that could easily call or 3-bet. This is a nice problem to have: the cutoff opens fairly wide, and you will have position after the flop if the blinds get out of the way.
The short answer
Call hands that play well when acting last after the flop. 3-bet strong hands for value and add a few bluffs that are happy to win immediately. Pay attention to the blinds: frequent squeezes make calling less attractive, while passive blinds let you see more flops.
Three useful words
A range is the full group of hands a player can reasonably hold. A 3-bet is a reraise before the flop. In position means you act after your opponent on the flop, turn, and river. A linear 3-bet range reraises the strongest hands in order. A polarized range reraises very strong hands plus some weaker bluffs while calling the playable hands in between.
Two quick examples
- Reasonable: The cutoff opens to 2.5 big blinds (2.5bb) and you have
K♥ J♥on the button. Calling is reasonable with passive blinds; 3-betting is reasonable if the cutoff opens wide and folds too much. - Not reasonable: You call with
K♣ 9♦because acting last fixes everything. Weak offsuit kings often make a second-best top pair and play much worse than suited hands such as king-queen suited.
Practice this spot first
King-jack suited is a perfect test because both call and 3-bet can make sense. Choose one, then explain what you want the blinds and cutoff to do.
Start from the cutoff opening range
A tight cutoff deserves less aggression than a player opening every suited hand. Start with a normal cutoff range. Change your response only when you can name the mistake, such as opening too many weak offsuit hands.
The blinds matter before they act. If they squeeze often, marginal calls lose value. If they rarely raise, the button gets to see more flops while acting last.
Build a playable calling range
Call with medium pairs, suited hands containing two cards from ten through ace, and suited hands that connect with many flops. Weak offsuit hands often make a second-best top pair. Acting last helps, but it does not rescue every attractive-looking hand.
Sometimes call with a strong hand too. If every strong hand 3-bets, opponents can assume your calls are weak and keep betting after the flop.
Choose the 3-bet shape deliberately
A linear range 3-bets the strongest hands in descending order and works well when the cutoff calls too wide. A polarized range combines value with bluffs that have blockers or playability and can work when the cutoff folds or 4-bets appropriately.
King-jack suited can call or 3-bet because both choices use the hand well. The better choice depends on the open size, rake, stacks, and how often the blinds squeeze.
Carry the range into position
After calling, the button can call a flop bet and attack later checks. After 3-betting, the button has more premium pairs and strong aces. The cutoff can still have sets and suited hands on low, connected boards.
Do not stop the review before the flop. For a hand that can call or 3-bet, compare how it plays on the same flop in both pots.
Rule of thumb: Acting last helps you use more of your hand's chance to win; it does not make every call profitable. Call hands that can use position and 3-bet hands that gain from pressure.
Keep studying
Continue into the cutoff’s response after the button 3-bets, test whether a 3-bet-or-fold strategy is actually appropriate, and revisit why one seat changes the profitability of every preflop hand.
