Settings: 3-handed · 100bb · SB 0.4bb · 5% rake, cap 10bb (small blind 0.4bb, big blind 1bb, 100bb stacks, 5% rake capped at 10bb; before the flop, rake only after a 3-bet). Solver: HoldemResources Calculator (HRC). 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.

Rake sources: ggpoker.com/poker-games/texas-holdem (fetched 2026-10-31); Rush rake and preflop rake confirmed on our own GG exports (972 of 1,034 pots, 210 of 211); regular tables' preflop rule from natural8.com/en/poker/texas-holdem (same network, fetched 2026-10-31); coinpoker.com/games/texas-holdem/ (caps and the preflop rule) and coinpoker.com/guides/poker-rake/ (5%), fetched 2026-10-31; natural8.com/en/poker/texas-holdem (fetched 2026-10-31; caps by players dealt in, 3-bet pots raked before the flop); acrpoker.eu/real-money/poker-rake-calculation/ (fetched 2026-10-31).

Rake: Wrong rake for a 3-handed GG table: this solve caps the rake at 10bb, which is right only for a 6-max hand folded to the button. GG caps an NL5 table with 3 players dealt in at $0.25 (5bb). A solve with GG's cap is queued.
