TT vs AJ: Preflop Odds & Equity
Pocket tens against ace-jack is a classic race — tens are about a 57/43 favorite preflop. Here are the exact equities and why the pair stays in front.

You hold T♠ T♥, the chips fly in, and villain shows A♣ J♦. It looks like a coin flip, and it nearly is — but the tens are the favorite at about 57/43. Ace-jack has two live overcards, yet a made pair that only needs to survive keeps the lead. As with every pair-versus-two-cards spot, the hand hinges on one question: does ace-jack pair up?
The headline equity
Each figure comes from a full board enumeration cross-checked with a Monte Carlo simulation:
| Matchup | TT equity | AJ equity |
|---|---|---|
| TT vs AJo (offsuit) | 57.0% | 43.0% |
| TT vs AJs (suited) | ~54% | ~46% |
Tens win a little over half the time. Suited ace-jack adds flush outs and closes the gap by a couple of points, but the pair holds the edge in both versions. Run the two hands through the equity calculator and you will watch it settle right at these numbers.
Why the tens hold the edge
Tens are a made pair; ace-jack is not. To win, ace-jack has to improve, and to lose, the tens simply need the board to miss the big cards. That head start is the whole story, even though the opponent holds an ace.
Count what ace-jack is drawing to:
- Pair an ace: three aces remain.
- Pair a jack: three jacks remain.
- That is six overcard outs, plus straight and flush chances.
Six outs across five board cards means ace-jack pairs at least one card roughly half the time — but not quite enough to overtake the tens’ head start. The tens also flop a set about 11.8% of the time, which adds a cushion on the boards where ace-jack does connect.
A worked example
Say 100 big blinds go in for a 200 big blind pot. Preflop, the tens own about 114 blinds of equity, ace-jack about 86. Now let a flop rewrite it.
Flop A♦ 8♠ 4♥: ace-jack pairs an ace and jumps to roughly 87%, while the tens fall to two remaining tens for a set, around 9%. Change the flop to 7♣ 6♦ 2♠, missing ace-jack completely, and the tens climb to about 90% while ace-jack must catch one of six cards on the turn or river. That is the race in motion — a near-even preflop split resolved almost entirely by whether the flop pairs the ace or the jack.
Why TT is slightly worse off than JJ
The instructive contrast is with a higher pair. Pocket jacks against AJ are the same made-pair favorite, but note that when the pair is below both of villain’s cards — as tens are below ace and jack — the pair is what we call “under” the overcards, with no clean dominating overlap. Tens stay ahead only because being a made pair beats needing to catch. Push the pair down to a small one like fives and the six live overcards start to bite harder. Counting exactly which cards are live is the core of combinatorics, and it is what separates a comfortable race from a marginal one.
From equity to a decision
At 57/43 this is a race, so the money is made in the margins — fold equity and pot odds — not the flip itself.
| Situation | Read | Line |
|---|---|---|
| You shove TT, called by AJ | ~57% | Favorite; happy to get it in |
| You call off TT vs an AJ shove | ~57% | Slight favorite; weigh stack risk |
| You shove AJ into a TT caller | ~43% | Dog, but fold equity can rescue it |
Lock in the anchor — TT is a ~57/43 favorite over AJo, ~54/46 vs AJs — and every tens-versus-broadway spot becomes a question of the surrounding math. Build the full line with preflop all-in odds, sharpen your counting with combinatorics, and explore the poker odds & math hub.
Cash game versus tournament
The raw 57/43 number means the same thing in every format, but what you do with it does not. In a deep cash game the goal is simply to get money in with an edge, and a 57% favorite is a hand you are usually happy to stack off — you will realize that edge over thousands of hands, and there is no penalty for busting beyond the chips themselves. In a tournament, chips you lose are worth more than chips you win because busting ends your equity in the prize pool. A near coin-flip like this one is exactly where good tournament players avoid getting all-in as the caller. Being the aggressor changes the picture: if you shove TT and pick up fold equity, you often win the pot outright without ever seeing the 43% show up. That fold equity — not the hold-up percentage — is where the money is made in a spot this close.
How the equities shift by street
The preflop split is only the starting point; every card can swing it dramatically. Understanding the swings helps you read the spot when the money goes in later rather than before the flop.
| Board texture | TT equity | AJ equity |
|---|---|---|
| Preflop | ~57% | ~43% |
| Flop pairs the ace (e.g. A-8-4) | ~9% | ~91% |
| Flop misses both (e.g. 7-6-2) | ~90% | ~10% |
| Flop gives AJ a straight draw (e.g. K-Q-2) | ~55% | ~45% |
The takeaway is that this matchup is decided almost entirely on the flop. If the flop bricks for ace-jack, the tens are close to a lock; if it pairs a broadway card, the tens are suddenly drawing thin to their two remaining tens. There is very little middle ground, which is exactly why the spot feels so swingy at the table even though the preflop math is settled.
Common counting mistakes
Two errors show up constantly in spots like this. The first is treating “two overcards” as if they were more than six outs — players see the ace and imagine ace-jack is nearly even or ahead, when in fact six outs across a five-card board is not enough to overtake a made pair. The second is forgetting the pair’s own redraw: the tens are not dead when ace-jack pairs, because they can still make a set with their two remaining tens or back-door a straight or flush. Counting cleanly — six clean overcard outs for ace-jack, two set outs plus back-doors for the tens — is the same discipline that governs every race, and it is why combinatorics is worth drilling until it is automatic.
Frequently asked
What are the odds of TT vs AJ preflop?
Pocket tens win about 57% of the time against offsuit ace-jack, with ace-jack around 43%. Suited ace-jack narrows it to roughly 54/46. The pair is favored in every version.
Is TT ahead of AJ?

Why is TT vs AJ so close?
Ace-jack has six overcard outs — three aces and three jacks — plus straight and flush chances. It connects often enough to win over 40% of the time, which is why the spot feels like a flip even though tens are favored.
Should you race TT against AJ?
As a 57/43 favorite, getting it in is fine in most cash games. In tournaments the edge is thin, so fold equity from being the aggressor often matters more than the raw hold-up percentage.
