How wide each seat opens

The share of hands each seat plays when it is folded to. Every seat raises; the small blind also limps. Pick a seat for its chart and its answers to an open.

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.

UTG	26%	70%	4%	QQ+, AKs, A5s-A4s, KJs, QJs, 54s, AKo

Each row is the big blind against an open from that seat. The hands listed re-raise more often than they call.

What these charts assume

Eight players, each with 50 big blinds.
Blinds of 0.5bb and 1bb, and the big blind posts a 1bb ante for the table.
Opens are to 2bb, and to 3bb from the small blind, the only seat that may limp.
3-bets are to 6bb in position, 7bb from the small blind and 8bb from the big blind (11bb against a small blind open). Any raise may be all-in.
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.
