PREFLOP · FIELD NOTE
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 benefit from position and can handle many flops. 3-bet strong hands for value and mix in a few hands that benefit from folds. Pay attention to the blinds: aggressive squeezers make calling less attractive, while passive blinds let you see more flops in position.
Three useful words
In position means you act after your opponent postflop. A linear 3-bet range simply raises the strongest hands in order. A polarized range raises very strong hands plus some weaker bluffs, while calling the playable middle.
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. Baseline strategy assumes a coherent opening range; exploitative adjustments begin only after you identify a meaningful deviation.
The blinds matter even before they act. Aggressive squeezers reduce the value of marginal flats. Passive blinds let the button realize position more often.
Build a playable calling range
Calls favor suited broadways, medium pairs, and suited hands that retain equity across many boards. Offsuit hands with domination risk often perform worse than their raw equity suggests. The button’s positional advantage helps, but it does not rescue every attractive-looking hand.
Protect calls with some strong hands when the structure allows it. If every premium becomes a 3-bet, the flatting range can be pressured too easily 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 often mixes because both calling and 3-betting preserve useful properties. The correct frequency changes with open size, rake, stacks, and blind behavior.
Carry the range into position
After a call, the button can float, delay bets, and apply river pressure. After a 3-bet is called, the button owns a stronger high-card range but must respect cutoff sets and connected-board coverage.
Do not study the preflop node in isolation. For each mixed hand, compare the flops it prefers in the called pot with the flops it reaches after 3-betting.
Rule of thumb: Position increases realization; it does not replace range discipline. 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.
