Why the odds look like this: domination

Both hands share a card, so AJ offsuit mostly needs to pair its kicker without AK offsuit improving. Dominated hands are usually close to a 3-to-1 underdog, and ties are common when the board plays. When AJ offsuit wins, it is most often with two pair (37% of its wins) or one pair (32%).

How to play AK offsuit vs AJ offsuit

Domination is why weak aces and kings play poorly against early-position raises. With the better kicker, expect to get paid on boards that pair the shared card.

Use these numbers at the table

Preflop equity tells you how often a hand wins if all the money goes in before the flop. To decide whether a call is profitable, compare your equity with the pot odds you are getting: use the pot odds calculator.

Do suits matter?

Yes, a little. Suited hands make flushes more often, and when two hands share a suit they block each other's flushes. That is why the same two hands can differ by one or two percentage points depending on suits. The figures above are exact for the example cards shown.

How we calculated these odds

We dealt out every possible five-card board (1,712,304 of them) for the example hands and counted wins, losses and ties. There is no sampling error: the numbers are exact for those cards.
