In heads-up limit Omaha 8, how do I play A-A-2-3 on the button?
Heads-up, PokerToast's limit Omaha 8 solver raises with A-A-2-3 rainbow on the button 99.9% of the time.
The spot
- Game: heads-up limit Omaha 8, Before the flop.
- You: A♠ A♦ 2♣ 3♥ (your hole cards): A-A-2-3 rainbow: a pair of Aces with the three best low cards.
- Your opponent: is in the big blind and has not acted.
- Pot before this street: 1.5 small bets.
- Pot size and the numbers: the solver groups pots by size: its numbers here are averages over every pot of up to 2.5 small bets at this point, so in exactly this pot they would be a little different.
The solver's numbers
| Play | How often (strategy) | Worth from here on (EV estimate, small bets) |
|---|---|---|
| Raise | 99.9% | +2.73 |
| Limp (call) | 0.1% | +2.00 |
| Fold | 0.0% | +0.00 |
Measured on 383 play-outs of this situation. The highlighted row is the play that measured best.
Why, in plain words
Raise is worth about 0.73 small bets more than limp (call) on average from here on: putting more chips in now pays with this hand.
What popular strategy articles say
A-A-2-3 (double-suited) is the most powerful starting hand in Omaha 8; raise it.
What strategy articles found by web search said on 2026-10-08 (PokerNews, Card Player, PokerStrategy, pokerskill and similar; mostly written between about 2007 and 2015, and mostly for full-ring games with several players in the pot).
Heads-up, the solver agrees: its main play is raise (99.9%).
Heads-up vs multiway
The numbers above are for heads-up play (two players). Most published advice is written for full-ring games with several players in the pot, so part of any difference can come from that.
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 (here:
0|B|A2-3-rAb|S|), 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.
