Preset: Rush & Cash, all stakes (NL2 to NL200), 6-max, 100bb stacks, 5% rake capped at 3bb. Solver: HoldemResources Calculator (HRC) (HRC CI 26.89). A jackpot fee on bigger pots is not in this solve, so lines that build big pots may be slightly too loose. Bet sizes are the solved ones; a size that is not here plays like the nearest one.

Tree: Two HRC solves of this game in one: the extra-sizes solve (3-bets to 2x, 3x or 4x, 4-bets to 2.3x or 3x or all-in) wherever it has every move of the base solve, and the base solve where the extra-sizes one allows no second caller (overcalls).
