Preflop Charts (PokerCoaching)

A reference artifact, not a read. Three sets of charts covering the preflop decision:

• Raise First In (RFI) — what to play when everyone folds to you.
• Facing RFI — how to play when someone has raised before you.
• RFI vs. 3-bet — how to play when you raised and someone yet to act 3-bets.

The assumptions the charts are built on

These matter, because a range chart is only valid inside its stack and sizing assumptions:

• 100 big blind effective stacks with an ante in play; the authors say they apply down to roughly 50bb and larger.
• In position: 2.5bb open · 3-bet to 3× the opponent’s raise · 4-bet to 2.5× the opponent’s 3-bet.
• Out of position: 3.5bb open · 3-bet to 3.5× · 4-bet to 2.75×.

The caveat they put in their own instructions

“These charts are an excellent default, but playing a default strategy in all situations will result in you being a roughly break-even poker player. Adjust to take advantage of whatever your opponents do incorrectly and the money will flow your way.”

That line is the actually interesting content, and it generalizes past poker: a solved baseline gets you to break-even, and all the edge lives in deviating from it in response to a specific opponent’s specific error. The chart is the floor, not the strategy.

Connections

• The default-versus-deviation structure is the same shape as the exploitability arguments in Game Theory — an equilibrium strategy is unexploitable and unprofitable against bad players, which is why the baseline earns zero.
