PLO Hand Trainer

Which of two Omaha starting-hand classes is stronger, all in preflop against one random hand of the same size. There are 256 questions across 4, 5 and 6-card PLO. It is a hand-reading drill, not a strategy drill: it will not tell you whether to raise, because that depends on the whole game tree and we do not have a solver for it.

No, and that is the single most useful thing this drill teaches. Two big pairs, double-suited wins 67.5% against a random hand while AAxx, rainbow wins only 63.2% — so the two pairs are the better hand by 4.3 points. Suits carry far more weight in Omaha than Hold'em players expect, and a bare pair of aces with disconnected rainbow side cards is a mediocre holding.

Because we cannot honestly grade them. Our equities carry a 95% margin of 0.2 percentage points, which is 0.3 points on a difference between two classes. 5 of the possible pairs sit inside that margin, so there is no measurable right answer and marking you wrong would be inventing one. They are left out rather than guessed at.

Our own simulation. Each class was run over 400,000 seeded runouts — 16,400,000 in total, seed 20260917 — using the same Omaha evaluator as our calculators, enforcing the exactly-two-hole-cards rule, all in preflop with all five board cards dealt. Chopped pots count as half. You can reproduce it; the method is on our data and methods page.

Yes, each has its own question set — 102 at four cards, 77 at five and 77 at six. The classes differ between them, and so do the answers: equities flatten as cards are added, so the gaps get smaller and the reads get harder.
