The button, at each depth
The same seat with more behind it. A deeper stack has room to play after the flop, so it raises more hands and shoves fewer.

How to read a chart
Each grid holds all 169 starting hands. Pairs run down the diagonal from aces to twos, suited hands sit above it and offsuit hands below.
Amber is a raise, red is all-in, teal is a call, violet is a limp and grey is a fold. A cell in more than one colour is a hand the solver plays more than one way: the wider a colour, the more often.
A range such as "22+, A2s+, K9s+" reads as every pair, every suited ace, and suited kings from K9s up. An "s" is suited and an "o" is offsuit.

Questions
What is a preflop chart?
A grid of all 169 starting hands that shows what to do with each one in a single spot: your seat, your stack, and the action before you. One chart answers one spot, which is why there is a page for every seat at every stack depth.
What is an RFI chart?
RFI means raise first in: the hands a seat opens when everyone before it has folded. It is the first chart on every seat page here, and the one to learn first, because every other spot starts from it.
Why do the ranges change with the stack?
A shorter stack has less room to play after the flop, so hands that need it lose value and hands that can go all-in gain it. On the button the solver opens 43% at 20bb, 52% at 40bb and 54% at 50bb. At 20bb every re-raise is a shove; from 40bb there are sized 3-bets and 4-bets.
Are these charts for cash games?
No. They are for 8-max tournaments, where the big blind posts an ante for the table. That ante puts an extra big blind in every pot, which widens every range, and the deepest stack here is 50bb.
Why is a cell more than one colour?
The solver plays that hand more than one way, and the bars show how often it takes each. The plays earn almost the same, so at the table either is fine. The written range lists each hand under the play it makes most often.
How accurate are the charts?
They are solved for this exact game. Pots that see a flop are valued with a model built from postflop solves, and every chart passes the same check: no seat can gain more than 0.001bb a hand by playing differently. They maximise chips, with no ICM.
What about stacks under 20bb?
At 10bb and 15bb the charts are push/fold: every hand is a shove or a fold, and there is a separate set of pages for them.
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, from 10bb push/fold up to 50bb with 3-bets and 4-bets.
