    Exploitability measures how far a chart is from perfect play, so lower is better. Every flop in the library is solved by itself. No chart is estimated from its neighbours.

    Rich sizing for bets and raises, on every street

    Nine bet sizes. Eight raise sizes. Ten on the river.

    • Betting on the flop and turnNine sizes: 20, 33, 50, 70, 100, 125, 150 and 200% of the pot, and all-in.
    • Raising on the flop and turnEight sizes: 33, 50, 70, 100, 125, 150 and 200% of the pot, and all-in.
    • Leads and donk betsThe player out of position leads with the same sizes, in some spots without the 20%.
    • The river, solved liveTen sizes: 20, 33, 50, 66, 75, 100, 150, 200 and 300% of the pot, and all-in. Six raise sizes: 33, 50, 80, 125 and 200%, and all-in. Solved in under a second, to 0.05% exploitability.

    A size that would put more than two thirds of the remaining stack in the pot becomes the all-in, so shorter stacks show fewer sizes.

    The rainbow on the right: the river’s bet sizes, from a fifth of the pot to three pots, and all-in. 6-max, 20 big blinds. Lojack raised, big blind called, nobody bet until the river 7♥ 6♦ 5♠ Q♠ J♣.
    How often the button chose each size when the big blind checks to it, flop by flop. On these six flops it used five of the nine, in a different mix every time. A tree with two sizes can only ever answer with those two.

    The library fills up every day.

    Seven machines have been solving the library for months, about 36,000 flops a day. Each stack depth is solved from 3-max up to 9-max, then the next depth starts.

    LiveThis table is the library itself, updated every day as it grows.
