Settings: 4-max · 100bb · SB 0.5bb · 5% rake, cap 3bb (small blind 0.5bb, big blind 1bb, 100bb stacks, 5% rake capped at 3bb; before the flop, rake only after a 3-bet). Solver: HoldemResources Calculator (HRC) (HRC CI 20.31). 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: Wrong rake for GG: this solve caps the rake at 3bb, but GG caps NL200 at $4.50 (2.25bb) with 4 players dealt in and $3 (1.5bb) with 3. A solve with GG's caps is queued.
