Pot-Limit Omaha plays nothing like Hold'em before the flop — four cards, much closer equities, and "the nuts or nothing" hand values. You'll be dealt four cards in a position; decide whether to open-raise or fold. Every hand is graded against its real all-in equity, computed live — not a lookup table.
You'll be dealt four cards in a position. Choose Open or Fold, then see the hand's computed equity and the verdict.
When you're dealt a hand, the trainer runs a Monte Carlo simulation right in your browser: it deals thousands of random opponent hands and boards, plays each one out under the Omaha rules (use exactly two of your four cards and three of the five board cards), and measures how often your hand wins. That win rate is your hand's all-in equity versus a random hand — a fact, computed from the rules of poker, not copied from any chart.
It then compares your equity to a position threshold. The thresholds are calibrated so that each seat opens roughly the standard fraction of hands — tightest in early position, widest on the button. So "Open" means your hand lands in the top slice you'd profitably raise from that seat; "Fold" means it doesn't.
You're dealt four hole cards and must use exactly two. That makes value about how the cards work together, not raw high-card strength:
For reference, the premium benchmark — AAKK double-suited — runs about 70% equity against a random hand, while disconnected rainbow junk sits in the low 40s. You'll see those numbers live as you play. For Hold'em, see the preflop range trainer and range charts.
