Live 5/5/10 PLO: Top Two Pair + Gutshot on the Turn, Should You Call?

In a 5/5/10 Pot-Limit Omaha game, Hero hits top two pair and a gutshot straight draw on the turn. Facing an unknown opponent's lead bet, should they call? This article analyzes the hand details and decision logic.
Hand Background
Live 5/5/10 (small blind 5, big blind 5, mandatory straddle 10) Pot-Limit Omaha (PLO) game, 9-handed, time rake.
- V1: Just sat down, stack 500, Middle Eastern middle-aged male, unknown style.
- V2: Fish, stack 1000.
- Hero: Covers the table, stack over 1500.
Action
-
Preflop: V1 limps from UTG, V2 limps from MP, Hero on the CO with A♥K♥ Q♠9♠, raises to 50. Button (passive player, stack 1500) calls, V1 and V2 both call. Four-way pot, pot 220.
-
Flop: A♠ T♣ 7♣ (one club draw). Everyone checks.
-
Turn: Q♦ (board A♠ T♣ 7♣ Q♦). V1 leads for 100, V2 folds, Hero to act. Hero's current hand: A♥K♥ Q♠9♠, resulting hand strength: top pair A + top pair Q (i.e., top two pair) plus a gutshot straight draw (K-J-10-9, etc., but actually the gutshot is? Since the board has A-T-Q and Hero's hand has K-9, making a straight requires J? Actually it's KQJT9? Wait, it's K-T? To be precise, in PLO Hero's hole cards are AKQ9, combined with the board: top two pair (A and Q), and a gutshot straight draw: if the river is J, then the straight is KQJT9, but only with K and 9, actually only one J makes the straight (i.e., gutshot). Additionally, there is a backdoor flush draw (hearts and spades? Hero has A♥K♥, the heart flush draw is already dead since the board has no hearts, clubs are the draw suit, Hero has no clubs), so only a gutshot straight draw.
Decision Analysis
Facing an unknown opponent V1's lead bet (100 into a 220 pot), Hero needs to decide whether to call or fold.
Reasons to Call
- Relatively strong hand: Top two pair is a made hand in PLO, plus a gutshot straight draw, with improvement potential.
- Pot odds: Calling 100, the pot becomes 420, immediate pot odds about 4.2:1. The gutshot straight draw hits on the river about 4/44 = 9.1% (about 10:1), but combined with the value of two pair itself and implied odds (if the straight hits, potentially winning more), the odds are acceptable.
- Opponent's range: V1 just sat down, could limp with any hand. A lead bet could represent a weak made hand (e.g., one pair + draw) or a pure bluff.
Reasons to Fold
- Strong hands in opponent's range: V1 could have a set (e.g., TT, 77) or two pair (AT, A7, etc.), or even a straight (KJ? On the turn Q, KJ makes KQJT9 straight, but the flop was A-T-7, turn Q, so indeed KJ makes a straight. Also J9 makes a straight? J9 would be J-T-9-8-7, missing an 8, so no. But KJ is the nut straight. Additionally, sets are possible.
- Hero's draw is weak: Only one gutshot, and two pair is easily outdrawn. If V1 holds AT or A7, Hero's two pair is outdrawn; if V1 holds KJ, Hero is almost drawing dead.
- Position disadvantage: After calling on the turn, if Hero does not improve on the river, it will be difficult to continue facing a potential heavy bet from V1.
Recommendation
In PLO, top two pair plus a gutshot is usually a medium-strength hand. However, considering the opponent is unknown and a lead bet often indicates a strong hand, folding is the safer choice. Especially since Hero's gutshot is not the nuts and implied odds may not be high (if the opponent holds the nut straight, Hero is drawing dead). Therefore, conservative play suggests fold.
