Pre-computed GTO mixed strategies

PioSolver costs hundreds of dollars, needs a serious PC, and takes real study time to operate. But here's the thing: for preflop, the answers barely change. UTG's opening range at 100bb 6-max is essentially settled science. So instead of making you solve anything, Solver-lite ships the solutions: Nash-near mixed strategies for 33 preflop spots that come up constantly, displayed on a color-coded 13×13 grid you can read in seconds. The original 9 spots are free with no signup; ELITE unlocks the other 24 (SB defense, every facing-3-bet position, 3-bet-or-fold lines, and 40bb/25bb depths).

It's for micro-stakes players who keep hearing "the solver mixes there" and want to see what that actually looks like — without buying software. Loads instantly, right in the browser.

How to use it

1. 1.Pick a spot — e.g. "BTN open" or "BB vs CO open".
2. 2.Read the frequency bar: it shows how much of the whole range raises, calls, 3-bets, or folds in that spot.
3. 3.Scan the 13×13 grid. Solid-colored hands are pure actions; split cells are mixes — the proportions show the frequencies.
4. 4.Compare against what you actually do. The gap between your default and the grid is your study list.

The methodology, honestly

The frequencies are pre-computed and calibrated to match published solver output and free published charts for 6-max with standard sizings — "Nash-near", not a live equilibrium computation. Every spot cites its calibration source in the code. The 40bb and 25bb open variants follow the same approach, calibrated against free published MTT charts; 25bb is deliberately kept as raise-or-fold because it sits above honest push-fold depth (that switch happens around 15bb — see the push/fold charts tool). Change the assumptions (antes, different open sizes) and the exact mixes shift, though the shape of every range stays recognizable. That's the honest trade: 33 fixed spots, instantly, versus arbitrary trees in paid software. At micro stakes, these spots are easily 80% of what matters preflop.

One practical warning: don't try to replicate mixes at the table by randomizing. Your opponents at NL2-NL25 aren't tracking your frequencies. Play the majority action of each mix consistently, and spend the saved brainpower on postflop decisions.
