The Button is the most profitable seat in poker — you act last postflop every hand. GTO exploits this by opening extremely wide, often 45–50% of hands at 100bb. If you are not stealing aggressively from the BTN, you are leaving money on the table. At 40bb you are in the mid-stack zone — deep enough for postflop play but shallow enough that implied odds are reduced. GTO tightens slightly vs 100bb, cutting speculative hands like small suited connectors that need deep stacks to realize equity. Below is the GTO range grid for BTN at 40bb (6-max, rake 5% cap $3) — green = raise, amber = call, red = fold. Hover any hand for exact frequencies and EV.

From the Button, open any ace, any suited king, most suited connectors, and even hands like T8o and 97s. Your edge comes from position — you will outplay opponents postflop. Defend vs 3-bets by calling with suited hands that realize equity well. Mid-stack strategy: you can still open-raise normally, but size down 3-bets and avoid calling 3-bets with speculative hands. Pairs and suited broadways go up in value; small suited connectors go down.
Pro tip: BTN is where most players leak the most EV by opening too tight. If your BTN VPIP is under 40% at 100bb, you are likely over-folding — drill this chart until 45%+ feels natural.
GTO open-raise frequency for BTN at 40bb depends on rake and field, but our TexasSolver-based chart (0.5% exploitability, 5% rake cap $3) shows the solver-preferred raise/call/fold mix for all 169 hands. Hover the grid above for exact frequencies per hand. Generally, BTN is widest (~48% at 100bb) — see the grid for 40bb specifics.
Use the 3-step method: (1) Quiz yourself — cover the grid and ask 'What does GTO do with AJo BTN 40bb?' (2) Check and note surprises. (3) Drill the borderline hands (the amber/mixed cells) with Lab's spaced-repetition drills. 10 minutes a day per position beats cramming.
These ranges are solved for 6-max cash, 5% rake cap $3, which matches most micro-to-mid stakes online games. At very low stakes with high rake or vs extremely tight/loose opponents, exploitative adjustments beat pure GTO — but you need to know GTO first to know when to deviate.
