Preset: Fast-fold, NL200 ($1/$2), 6-max, 100bb stacks, 5% rake capped at 3bb. Solver: HoldemResources Calculator (HRC) (HRC CI 24.97). 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.
