Settings: 6-max · 200bb · SB 0.5bb · 5% rake, cap 3bb (small blind 0.5bb, big blind 1bb, 200bb stacks, 5% rake capped at 3bb; before the flop, rake only after a 3-bet). Solver: HoldemResources Calculator (HRC) (HRC CI 24.64). 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.
