AK vs 22 Preflop: The Real Odds (and Why It Isn't a Coin Flip)
You got it all in with ace-king against pocket deuces, lost, and now you want to know whether you were even ahead. Short answer: you weren't. Against AK offsuit, the deuces have about 53% equity and AK has about 47%. The tiny pair is the favourite, every time, and the only reason anyone calls this a coin flip is that the margin is small enough to feel like one.
But that number moves more than you'd expect, and most sources quoting it are quoting a different figure without saying so. Every number in this article comes from enumerating all 1,712,304 possible boards for each exact suit combination, so you can check any of it yourself.
Win Percentage, Tie Percentage and Equity Are Three Different Numbers
This is why the internet cannot agree on this matchup. Search it and you will find 52.34%, 52.65% and 52.8% quoted as if they were the same thing. They aren't.
- Win percentage is how often the hand wins outright.
- Tie percentage is how often the board plays and the pot is split. It is small here, around 0.6%, but it is not zero.
- Equity is what you actually care about: wins plus half the ties. It is always slightly higher than the raw win percentage.
Take one exact case, deuces against AK sharing a single suit. The deuces win 52.34% of boards, AK wins 47.04%, and 0.62% split. Add half the ties to each and you get equity of 52.65 against 47.35. Three correct numbers describing the same hand. If you have ever wondered why two sites give you different odds for an identical matchup, this is usually why. Our guide to poker equity covers what the number means and how to estimate it on the fly.
The Suits Change the Answer
Here is the part almost nobody publishes. “AK vs 22” is not one matchup, it is several, and which one you are in depends on how many suits the two hands share.
The mechanism is flush outs. Every suit the AK shares with a deuce is a suit where one of its flush cards is already accounted for. Strip both overlaps away and AK gets its cleanest run at a flush, which is worth about three quarters of a percentage point across the whole matchup. Small, but it is the difference between the numbers you keep seeing quoted.

Against a Suited AK, the Deuces Aren't Favourites at All
Now the result that surprises people. Give the ace-king a suit and the flip stops being a flip.
22 against AKs, no shared suit: 49.92 for the deuces, 50.08 for the ace-king. The suited hand is very slightly ahead. If the deuces do hold one of AK's suits, it swings back to 50.30 against 49.70. Either way you are looking at the flattest matchup in hold'em, decided by a rounding error.
Being suited is worth roughly three points of equity here, which is a lot more than it is worth in most spots. That is because the deuces have almost no way to improve beyond a set, so the extra flushes go almost entirely uncontested. If you want the general version of that argument, our suited vs offsuit guide works through what suitedness is actually worth across the board.
Do Bigger Pairs Do Better? Up to a Point
The obvious next question is whether a bigger pair widens the gap. It does, and then it abruptly stops.
Read the bottom three rows again. Tens, jacks and queens are all worth about 57%, and if anything the number edges down as the pair grows. So the intuition that a big pair is meaningfully safer against AK is wrong past about tens. Queens against ace-king is the same race as tens against ace-king, which is worth remembering the next time you agonise over getting queens in preflop.
So Should You Get It In?
Here is the thing the odds table cannot tell you, and it matters far more than the matchup itself. Shoving AK and calling a shove with AK are completely different decisions, even though the hand and the equity are identical.
When you move all in with ace-king, most of your profit doesn't come from winning the race. It comes from the hands that fold. Every time your opponent lays down a worse ace, a suited connector or a small pair they didn't want to flip with, you win the pot without seeing a flop. That is fold equity, and it is why AK is such a strong shoving hand at short stacks.
Calling an all-in deletes that entirely. There is nothing left to fold out, so you are simply racing, and against any pair at all you are the underdog. The same hand that prints money as an aggressor becomes a marginal call the moment the chips come at you first.
Which is why the honest answer to “should I call off with AK here” is almost never about the deuces. It is about everything else in their shoving range: the worse aces you dominate, the broadway hands you flip against, the big pairs that crush you. AK performs well against a wide shoving range and badly against a tight one, and the deuces are just one line in that calculation. Drop the whole range into our equity calculator instead of eyeballing a single matchup.
And once stacks are short enough that shove or fold is the only decision left, the whole question simplifies. Our push or fold chart gives you the jamming ranges by position and stack, where AK is never a close call.
Common Questions About AK vs 22
What are the odds of AK vs 22 preflop? Against AK offsuit, pocket deuces have about 53% equity and AK has about 47%. The exact figure depends on whether the hands share a suit: 53.04% for the deuces when no suits overlap, 52.65% when one overlaps, and 52.26% when both do. Against AK suited the deuces drop to roughly 50%, so the matchup is genuinely dead even.
Is AK vs 22 really a coin flip? It is the closest thing to one in poker, but not exactly even. The deuces win around 52% of the time, AK wins around 47%, and about 0.6% of boards are split. Against a suited AK it does become an actual flip, with the two hands within a fifth of a percentage point of each other.
Why do the odds change when the hands share a suit? Because shared suits remove flush outs from one hand. When AK holds a suit that neither deuce holds, AK has more live flush cards. Each shared suit costs the AK a little and gains the deuces a little, which is why the deuces go from 52.26% up to 53.04% as the overlap disappears.
Do bigger pocket pairs beat AK more often? Yes, but it stops mattering sooner than most players think. Against AK offsuit, pocket fives have 55.0% equity, pocket eights 55.6%, and pocket tens 57.3%. From tens upward the number stops climbing: jacks are 57.2% and queens 57.2%. Every pair from tens to queens is about a 57/43 favourite, no better.
Should you call an all-in with AK against a small pair? The matchup alone should not decide it. Shoving AK yourself is strong because opponents fold a large part of their range, and that fold equity is where the money comes from. Calling a shove removes all of it and leaves you as a small underdog to any pair. That is why AK is a much better hand to move all-in with than to call all-in with.
Putting It Into Practice
You now know the number better than almost anyone at your table: a shade over 53% for the deuces, dead even if the ace-king is suited, and about 57% for any pair from tens up. What you should take away is not the decimals though. It is that the matchup is close enough to be irrelevant most of the time, and the decision is really about fold equity and about the rest of the range.
Which is a preflop skill, not a math skill. Knowing you were a 47% dog after the fact changes nothing. Recognising the spot before the chips go in is the part worth training.
