PLO preflop charts: free solver-derived ranges
At 6-max 100bb, the solve opens 17.6% of hands from UTG and 48.6% from the button. Between those two numbers sits most of the preflop money in PLO: which of the 270,725 starting hands play from which seat, and how the answer nearly triples as position improves. SolvePLO's preflop charts are that solve, decoded from MonkerSolver's own files, free in the browser.
What the solve actually opens
Exact open-raise widths by seat, from the same 6-max solves the charts display:
| Seat | 20bb | 50bb | 100bb | 150bb |
|---|---|---|---|---|
| UTG | 12.8% | 16.4% | 17.6% | 16.2% |
| HJ | 15.2% | 19.9% | 22.3% | 21.1% |
| CO | 19.1% | 25.1% | 30.5% | 30.0% |
| BTN | 26.2% | 35.3% | 48.6% | 51.8% |
Two patterns worth internalizing before you open a single chart. First, position is worth more than depth: at every stack size the button opens roughly 2.5-3x as wide as UTG, while going from 20bb to 150bb roughly doubles each seat's range. Second, the small blind is its own game: at 100bb the solve raises 33.6% of hands, open-limps just 6.8%, and folds the rest - the limp-heavy small-blind strategies common in live games belong to 20-30bb stacks, where the solve limps a quarter of hands. The full depth story, seat by seat and hand class by hand class, is on the stack depth reference.
What the charts include
Every standard 6-max cash spot at eight depths from 12bb to 200bb, plus heads-up at 100bb: open-raises for every seat, 3-bets against every open, the calls in between, and 4-bet responses. Each chart is the solver's frequency-weighted range - a hand that mixes raise and fold shows its real mix, not a rounded yes or no.
If you want the strength ordering behind the ranges rather than seat-by-seat decisions, the PLO4 hand rankings list all 16,432 hand classes by equity and by full-game solver EV, and the range frequencies reference shows what an opening or 3-bet range is actually made of.
How to study them
Pick the seat you play most and learn its open range first; for most online players that is the button or cutoff. Spend your attention on the borderline hands - you already know A-A-x-x opens and 7-3-2-2 rainbow folds, and the EV difference lives in the hands that are close. Then connect preflop to postflop: the free board lookups show how the ranges you just studied actually play on specific flops, which is where the reasoning behind each chart becomes visible.
