Settings: 6-max · 100bb · SB 0.4bb · 5% rake, cap 2.6bb (small blind 0.4bb, big blind 1bb, 100bb stacks, 5% rake capped at 2.6bb; 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.

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; wptglobal.com/poker/poker-table-rake (fetched 2026-10-31); natural8.com/en/poker/rush-and-cash (fetched 2026-10-31; caps $0.06 to $6, 3bb at every stake); the same GGNetwork pools as GGPoker, whose preflop rake we confirmed on GG exports; natural8.com/en/poker/texas-holdem (fetched 2026-10-31; caps by players dealt in, 3-bet pots raked before the flop).

Rake: Wrong rake for GG: this solve caps the rake at 2.6bb, but GG caps an NL5 table with 5 or 6 players dealt in at $0.50 (10bb), and it opens 3bb only. Hands from 6-handed tables are graded on the 3bb cap charts instead. A solve with GG's cap is queued.
