Opening ranges (RFI) by position

RFI is raise first in: what a seat does when everyone before it has folded. Each hand is listed under the play it makes most often. A hand under Split is one the solver plays more than one way; the grid shows how often.

Big blind defense

The big blind has already paid to see the hand and closes the action, so it continues with far more hands than any other seat. This is its answer to an open from each seat, everyone between having folded.

What these charts assume

  • Eight players, each with 20 big blinds.
  • Blinds of 0.5bb and 1bb, and the big blind posts a 1bb ante for the table.
  • Opens are to 2bb (3bb from the small blind) or all-in, and every re-raise is all-in. Only the small blind may limp.
  • Each chart is one line: a single raise, with every seat between it and you folded. Lines with callers and squeezes are in the trainer.
  • Chip EV. ICM is not modelled, so near the bubble or at a final table, play tighter.
  • Pots that see a flop are valued with a model built from postflop solves. No seat can gain more than 0.001bb a hand by playing differently.

Now play it

Knowing the chart is one thing. The trainer deals you these spots one hand at a time and prices each answer in big blinds.
