Heads-up vs multiway
This question is about heads-up play (two players), so there is no multiway version of it.
How these numbers were made
From PokerToast's own heads-up limit Omaha 8 solver, trained 19,095,762 iterations, exported 2026-10-05 18:07:15, 93,573 situations (version Y-19095762-20261005180715). It learned by self-play (Monte Carlo counterfactual regret minimization) for limit betting, at most four bets a street.
- How often is the solver's average strategy for this situation.
- Worth (EV) is an estimate measured after training by playing the situation out many times against the solver's own strategy: small bets won or lost from this decision on, compared with folding (0). It assumes an opponent who plays like the solver.
- Hand groups: the solver groups similar hands, so the numbers are for the group, not only these exact cards. Before the flop it groups your four cards by their low cards (A-2, A-3, other aces, 2-3), how many low cards you hold, suits (including a suited ace), pairs and high cards. After the flop it groups by your high hand and low hand on that board, the board itself, the pot and the betting so far on this street.
- Looked up when this page was built (2026-10-19); a newly trained solver changes the page and its version number.
