The solver's answer
The big blind's whole range
Check 86% Bet 14%
- ⅕ pot · 1.8 bb 13%
- ½ pot · 4.55 bb 1%
The big blind checks most of its range to the button; its few leads are small.

In a 6-max cash game at 100 big blinds, after the button opens to 2.5 bb and the big blind calls a 1.8 bb c-bet on an A♠ 7♦ 4♣ flop, the big blind checks the 5♥ turn with 86% of its range and leads with the rest: 13% for 1.8 bb and 1% for 4.55 bb, according to a solver answer published free by Poker Skill.
Why the big blind mostly checks this turn
- A turn lead is a bet into the player who bet the flop. Here the big blind checks 86% of its range to the button instead.
- The 5♥ completes straights for six-three, eight-six and three-two. Straights lead the most, 27% of the time, then second pair at 24%; every other kind of hand leads less often.
- The leads are small: a fifth of the pot is the size the big blind uses most, and half the pot is rare.

Each cell shows the share of the class's possible combos in the range.
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 0.6 bb, opens sized by the solver (2.5 bb here) and several bet sizes on each street. The button c-bets several sizes on the flop; this line follows its most-used one, 1.8 bb, which the big blind called. On the turn the big blind can check or lead a fifth of the pot or half the pot. 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.
