Play the right hands, from the right position. Interactive GTO preflop ranges built for serious cash game players.
Mastering Preflop Strategy: The RFI Charts
Welcome to the core of your preflop strategy. In modern 100bb deep cash games, your preflop decisions dictate how easily you can navigate post-flop. These interactive charts provide the exact Game Theory Optimal (GTO) opening ranges for every position at a 6-Max table. Before you memorize these hands, you must understand the rules of engagement.
Preflop Starting Hands
Select your position to view the recommended opening range.
Important: Use strictly for Raise First In (RFI) when everyone before you has folded.
How to Use The Tool
- Select your seat position at the top (UTG = Under the Gun, BTN = Button, etc.).
- Hover over each position to understand the strategic dynamics.
- Hands marked in Red are mathematically profitable opening raises. Hands marked in Grey are folds.
The Golden Rule: Unopened Pots ONLY
RFI stands for Raise First In. This means these charts apply strictly when every player before you has folded.
- If someone raises before you: Throw these charts out. You must switch to a “Facing a Raise” (3-bet/call) strategy.
- If someone limps before you: Throw these charts out. You are now in an “Isolation” scenario.
The Right Bet Size (Sizing)
Knowing what hands to play is only half the battle; you must also know how much to raise. In a standard 100bb deep game, use these GTO sizings:
- UTG, HJ, CO: Raise to 2.5bb (or 3bb in higher rake games).
- Button (BTN): Raise to 2bb – 2.5bb. We use a smaller size here because we have position and want to steal the blinds cheaply with a wide range.
- Small Blind (SB): Raise to 3bb – 4bb. You will be out of position post-flop, so you must charge the Big Blind a premium price to see the flop.
The Power of RFI: Attacking Dead Money
Why do we always raise and never just call the big blind (limp)? When you are the first player to enter the pot, your primary objective is to attack the “dead money” (the blinds). Raising gives you two ways to win the hand:
- Everyone folds, and you win the pot immediately without seeing a flop.
- You get called, but you go to the flop with the betting lead (initiative) and a strong, uncapped range.
The Limper Scenario
If a player before you just calls the big blind (a limp), the pot is no longer dead. They have shown interest in the hand.
- Do not over-limp: Limping behind them is a passive, losing play.
- Iso-Raise: You must either aggressively raise to isolate them (forcing the blinds to fold so you play heads-up in position) or fold. Your isolation range will be tighter, and your raise size must be larger (typically 3bb + 1bb for every limper).
