Solved for: GGPoker Regular tables, NL200 ($1/$2), Heads-up, 100bb stacks, 5% rake capped at 3bb. Solver: HoldemResources Calculator (HRC) (HRC CI 14.45). GG's jackpot fee on pots of 30bb and more is not in this solve, so lines that build big pots may be slightly too loose. Bet sizes are the solved ones; a size GG offers that is not here plays like the nearest one.
