Settings: Heads-up · 80bb · SB 0.5bb · ante 0.16bb · 5% rake, cap 2bb (small blind 0.5bb, big blind 1bb, an ante of 0.16bb from every player, 80bb stacks, 5% rake capped at 2bb; no rake when no flop is dealt). Solver: HoldemResources Calculator (HRC) (HRC CI 22.38). 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.
Fits exactly: no game we have checked.
Close: CoinPoker cash with antes NL50 (rake before the flop in 3-bet pots there, none here).
Rake sources: the ante from 93 of our own CoinPoker hands at $0.25/$0.50 with a $0.08 ante, played 2026-09-30; the caps and the preflop rule from coinpoker.com/games/texas-holdem/, fetched 2026-10-31.
