Settings: Heads-up · 30bb · SB 0.5bb · no rake · chip EV (small blind 0.5bb, big blind 1bb, 30bb stacks, no rake; chip EV: every chip is worth the same, as it is when only the winner is paid and heads-up). Solver: HoldemResources Calculator (HRC) (HRC CI 30.47). Bet sizes are the solved ones; a size that is not here plays like the nearest one.
