The solver's answer

Call 65% Raise 35%

A♠3♠ never folds: it calls most of the time and check-raises the rest, two options worth about the same.

The solver plays A♠3♠ along this line to this decision 79.04% of the time; otherwise it acts differently earlier in the hand.

Bets 1.8 bb

In a 6-max cash game at 100 big blinds, after the button opens to 2.5 bb, the big blind calls and the button c-bets 1.8 bb into 5.5 bb on a K♠ Q♠ 9♦ flop, the big blind calls with A♠3♠ 65% of the time and check-raises to 10 bb 35%, according to a solver answer published free by Poker Skill.

Why A♠3♠ calls or check-raises, and never folds

  • The price is low: calling 1.8 bb to win 7.3 bb needs 19.8% equity, and A♠3♠ has 51.4% against the button's bet.
  • Calling and check-raising are worth almost the same: 3.30 bb against 3.28 bb. The raise is a semi-bluff: it can win the pot now or make the nut flush later.
  • The big blind's nut flush draws as a group raise 41% of the time, against 15% for its other flush draws.

Where the numbers come from

The numbers come from a commercial solver's precomputed solution for a 6-max cash game at 100 big blinds, with a 5% rake capped at 15 bb and 2.5 bb opens. It allows one bet size at each decision. Here the button's c-bet is 1.8 bb into 5.5 bb and the big blind's raise goes to 10 bb. Two players see the flop. Pots with three or more players aren't covered, and neither are bet sizes outside this solution. Poker Skill read the numbers and wrote the explanation.
