Poker: Game Theory Optimal (GTO) & Solvers
The zero-sum intellectual combat arena: how modern Nash Equilibrium solvers (PioSolver, MonkerSolver) and exploitative node-locking consistently defeat human opposition.

- If a player bets \$100 into a \$100 pot, \( \alpha = \frac100200 = 50\% \). This means their bluff only needs to succeed 50% of the time to break even.
- The Minimum Defense Frequency (\( MDF \)) dictates that the defender must continue with at least 50% of their range to prevent the bettor from profiting with any arbitrary two cards.
โก Modern & New Ways to Beat Poker
While 2000s poker relied on gut reads and position, modern poker is won through computational range analysis and algorithmic node-locking:
Playing pure GTO leaves money on the table against bad players who make catastrophic tactical blunders.
Human intuition naturally gravitates toward standard bet sizes (half-pot to full-pot).
In online poker, physical body language does not exist, but digital telemetry does.
Playing against other GTO wizards results in zero profit after casino rake.

Equilibrium action frequencies from different table positions
| Table Position | GTO Open % of Hands | 3-Bet Frequency | Sizing | Key Bluff Candidates |
|---|---|---|---|---|
| Under the Gun (UTG) | 14.2% | N/A (First to Act) | 2.2x - 2.5x BB | A5s, A4s, KTs, QJs |
| Middle Position (MP) | 18.5% | 7.5% vs UTG | 2.3x - 2.5x BB | A3s-A5s, T9s, JTs |
| Cutoff (CO) | 26.8% | 10.2% vs MP | 2.5x BB | Suited Gappers (97s, 86s), K9s |
| Button (BTN) | 42.5% (Max Frequency) | 13.8% vs CO | 2.5x BB | All Suited Aces, Suited Connectors, Offsuit Broadways |
| Small Blind (SB) | 44.0% (Raise or Fold) | 15.5% vs BTN | 3.0x - 3.5x BB | Polarized: 75s, 64s, A2s, K8s |
| Big Blind (BB) | Defends 52.0% vs BTN | 14.2% 3-Bet | 4.0x BB (OOP) | A5s, K9s, Q9s, 65s, Pocket Pairs 22-88 |
- Zero Heat Guarantee: Poker is player-against-player. The casino earns its money via rake (typically 5% capped at $5-$10 per hand). Therefore, the casino welcomes world-class poker players and will never back them off or ban them for winning.
- Variance Reality: Due to bad beats and coin flips (e.g. AK vs QQ), a winning 10 BB/100 poker player can easily experience 20-buyin downswings over 50,000 hands. Bankroll management of 50-100 buyins is mandatory.
