Settings: 6-max · 100bb · SB 0.5bb · ante 0.16bb · 5% rake, cap 8bb (small blind 0.5bb, big blind 1bb, an ante of 0.16bb from every player, 100bb stacks, 5% rake capped at 8bb; no rake when no flop is dealt). Solver: HoldemResources Calculator (HRC) (HRC CI 24.89). 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, callers first: the callers solve (its raises grow by 1bb, or 1x, for each player who called before) has every one of the 1,323 spots here, so the base solve gives none of them.

This spot: from the callers solve (sizes: opens 2.0bb + 1.0bb, 2.5bb + 1.0bb, 3.0bb + 1.0bb; 3-bets 2.0x + 1.0x, 3.0x + 1.0x; 4-bets 2.3x, all-in; 5-bets all-in; HRC CI 24.58).

Rake sources for the games it fits: 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.
