Big blind at 20bbBig blind at 40bbAll 50bb charts3-bet ranges at 50bb

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, in the big blind and everywhere else, and prices each answer in big blinds.
