The exactly-two-cards rule
You get four hole cards in Omaha, but only two of them play — locked with exactly three from the board. Miss this and you'll misread your hand and lose stacks.
The rule, locked
Two of your four hole cards plus three of the five board cards equals your hand. Always. Not one, not three, not four. The 2-and-3 split never changes for anyone.
The flush trap
One suited card in your hand is worthless for a flush. A flush needs TWO of your hole cards in that suit, no matter how many of it land on the board.
The board is all hearts. You hold the Ace of hearts. Do you have a flush?
Fix: bring two of the suit
Hold two spades with three spades on the board, and now you've got a genuine flush. Same rule — two from hand, three from board — this time working for you.
The full-house trap
A paired or tripped board looks terrifying, but it can't play alone. Your two hole cards still have to actually complete the boat (a full house) or the quads (four of a kind).
What is your best 5-card hand here?
Straights, same math
Four-to-a-straight on the board still needs two cards from your hand that fit the run. Pick your two, take exactly three from the board, then read the five.
- Every Omaha hand is exactly two hole cards plus exactly three board cards — no other split exists.
- One suited card can never make a flush; you need two of that suit in your hand.
- The board never plays itself — a scary board only counts if your two cards complete it.
- For straights and boats alike, pick two from hand and three from board, then read the five.
- In doubt at showdown, physically count 2 + 3 to confirm your real hand.
