The solver's answer
The big blind's whole range
Call 56% Fold 27% Raise 17%
The big blind check-raises 17% of its checking range: its best hands and its straight draws.
8♦6♠5♣
- Pot
- 5.5 bb
- Behind
- 97.5 bb
- Button
- Bets 1.8 bb
In a 6-max cash game at 100 big blinds, after the button opens to 2.5 bb and the big blind calls, then checks an 8♦ 6♠ 5♣ flop and faces a 1.8 bb c-bet into 5.5 bb, the big blind check-raises to 10 bb with 17% of its range, calls 56% and folds 27%, according to a solver answer published free by Poker Skill.
Which hands check-raise, and why
- Value: straights check-raise 90% of the time, two pair 55% and sets 43%. Low, connected flops like this one are good boards to check-raise, with sets and two pair for value and draws alongside them.
- Draws: open-ended straight draws raise 41% and gutshots 25%, against 4% for hands with no draw. A raise with a draw is a semi-bluff: it can win the pot now or improve later.
- Its weakest hands, no pair and nothing better than queen-high, raise 30% of the time and fold 46%.
- Only about half of the big blind's range gets here: on this flop it leads into the button 47% of the time and checks 53%.
