Going all-in preflop is the highest-variance decision in poker. The right shove at the right time prints money; the wrong one torches your stack. This guide breaks down the exact equity numbers, hand matchups, and stack-depth scenarios so you know when pushing all your chips in before the flop is a winning play — and when it’s just gambling.

Preflop All-In Equity: The Numbers You Need to Know

Before we talk about when to shove, you need to understand how often each hand actually wins. These numbers come from running millions of Monte Carlo simulations, and they don’t lie. Every serious player should have these matchups internalized.

Premium Pair vs. Premium Pair

The classic cooler situations. When two big pairs collide preflop, money is almost always going in — the question is just how dominant the bigger pair is.

Matchup Favorite Equity Underdog Equity Notes
AA vs KK 81.9% 18.1% The ultimate cooler. KK wins less than 1 in 5 times.
AA vs QQ 82.4% 17.6% Slightly better for AA since QQ has fewer straight outs.
AA vs JJ 80.2% 19.8% JJ picks up a bit more equity from straight possibilities.
KK vs QQ 81.5% 18.5% Same dynamic as AA vs KK — overpair dominance.
KK vs JJ 81.1% 18.9% KK is a massive favorite.
QQ vs JJ 81.5% 18.5% One-gap pairs are consistently ~81/19.

Key takeaway: An overpair vs. underpair matchup is always roughly 80/20. You’re never folding the overpair, and you’re never wrong to get it in with the underpair either — you just need to accept you’re on the wrong side of variance 4 out of 5 times.

I’ve been on both sides of AA vs KK more times than I can count. The one that sticks with me is a $2/$5 session where I had KK, the guy across the table 4-bet me, I 5-bet shoved, and he snapped with aces. A king flopped. He stared at the board for a solid ten seconds without blinking. I felt terrible and grateful at the same time — which is pretty much the emotional summary of the KK vs AA matchup.

Pair vs. Two Overcards (The Classic “Coin Flip”)

People call these “coin flips,” but they’re not really 50/50. The pair is always a slight favorite.

Matchup Pair Equity Overcards Equity Notes
JJ vs AKs 54.2% 45.8% Suited overcards close the gap.
JJ vs AKo 57.0% 43.0% Offsuit AK is noticeably worse.
QQ vs AKs 54.4% 45.6% QQ blocks one overcard, doesn’t matter as much as you’d think.
QQ vs AKo 57.2% 42.8% QQ is solidly ahead.
TT vs AKs 54.0% 46.0% Both overcards are live — closest to a true flip.
TT vs AKo 56.8% 43.2% The pair always has an edge.
77 vs AKs 53.4% 46.6% Smaller pair, slightly less equity but still ahead.
22 vs AKo 52.5% 47.5% Even deuces are technically favored. Barely.

Key takeaway: A pair vs. two overcards runs between 53% and 57% for the pair. The suitedness of the overcards matters — suited adds roughly 3% equity. These are profitable all-in spots for both sides in the right context, but the pair has a consistent mathematical edge.

Dominated Hands: Where People Lose Their Stacks

This is where the real money gets burned. Getting all-in preflop with a dominated hand is one of the most expensive mistakes in poker.

Matchup Dominator Equity Dominated Equity Notes
AK vs AQ 73.4% 26.6% AQ is crushed — shared ace, dominated kicker.
AK vs AJ 74.0% 26.0% Even worse for AJ.
AK vs AT 74.2% 25.8% AK dominates all Ax hands hard.
KQ vs KJ 73.8% 26.2% Same shared-card domination pattern.
AK vs KQ 74.6% 25.4% KQ is in terrible shape.
AA vs AKs 87.2% 12.8% Worst case scenario for AK — one of the aces is dead.
AA vs AKo 93.0% 7.0% Offsuit AK is nearly drawing dead vs AA.

Key takeaway: Domination is brutal — the dominated hand wins only about 25% of the time. This is exactly why you don’t want to be shoving ATo into a tight player’s 4-bet range. When your opponent only 4-bets AA, KK, QQ, and AK, your ATo is either crushed by a pair (~80/20 against) or dominated by AK (~74/26 against). Either way, you’re torching money.

When You SHOULD Shove All-In Preflop

Knowing the equity numbers is step one. Knowing when those numbers actually justify putting your tournament life or full cash game stack on the line is step two. Here are the situations where preflop all-ins are clearly profitable.

1. Short Stack in a Tournament (Under 15 Big Blinds)

This is the single most common correct preflop shove scenario. When your stack drops below 15 big blinds in a tournament, you lose the ability to play postflop poker effectively. Your only moves become shove-or-fold.

The math is straightforward: if you have 10 BBs and open-raise to 2.5 BBs, you’ve committed 25% of your stack. If someone 3-bets, you either fold (wasting 25% of your stack) or call with a hand that might not be strong enough to justify it. Shoving eliminates this awkwardness — you either pick up the blinds and antes uncontested, or you go to showdown with fold equity already factored in.

General shove ranges by stack depth:

  • 10-15 BBs: Shove with any pocket pair (22+), A2s+, A7o+, K9s+, KTo+, QTs+, JTs. From late position, widen significantly.
  • 6-10 BBs: Shove with any pocket pair, any ace, K5s+, K8o+, Q8s+, QTo+, J9s+, T9s. Position matters less because fold equity is lower.
  • Under 6 BBs: Shove almost any two cards from the button and small blind. From earlier positions, shove any pair, any ace, any king, Q5s+, Q8o+, J8s+, T8s+. You can’t afford to wait.

I learned this lesson the hard way in my first few tournaments. I’d sit with 8 BBs waiting for a “good hand” and blind down to 4 BBs, at which point even AA has almost no fold equity. By the time I shoved my 3 BB stack with KJs, two people called because the pot odds were too good to fold. If I’d shoved at 8 BBs, I probably take it down uncontested with the same hand.

2. You Have AA or KK and Someone Has Already Raised

This sounds obvious, but the execution matters. With aces or kings against a raise and potentially a 3-bet, the correct play is almost always to get the money in preflop.

The exception: super deep-stacked cash games (300+ BBs effective) where you might prefer to flat the 3-bet with KK to control pot size against a very tight opponent’s range. But in a tournament or a 100 BB cash game? Get it in. You have 80%+ equity against any single hand.

The numbers support this aggressively. Even if your opponent is only shoving AA/KK/QQ/AKs (an extremely tight range), your KK has 59.4% equity against that combined range. You’re printing money.

3. You’re in the Blinds Facing a Late Position Steal

When a loose player opens from the cutoff or button, your reshove range from the small blind or big blind should be much wider than most recreational players think — especially with 15-25 BBs.

If the button opens to 2.5 BBs and you have 18 BBs in the big blind, a shove risks 15.5 BBs more to win the 4 BBs already in the pot (their raise + SB + BB + antes). You need to win the pot about 79.5% of the time to break even. Against a button opening range of 40%+ of hands, your fold equity alone with hands like K9s, QTs, or A4s makes this profitable — and when called, you often have decent equity.

4. Isolation Shove Against a Limper

In live poker especially, you’ll see players limp in with weak holdings. If you have a short-to-medium stack (15-25 BBs) and a reasonable hand, shoving over a limper is highly profitable. You combine fold equity (limpers have weak ranges) with decent equity when called.

When You Should NOT Shove All-In Preflop

1. Deep-Stacked with a Medium Pair

You have 100 BBs and JJ. Someone 3-bets you. Shoving is almost always wrong here. Against a standard 3-betting range, JJ does okay — but against the range that calls a 4-bet shove of 100 BBs, JJ is in terrible shape. Most players who call a 100 BB shove have QQ+/AKs at minimum, and JJ has only about 36% equity against that range.

The better play: 4-bet to around 2.5x their 3-bet and be prepared to fold to a 5-bet, or flat the 3-bet and play postflop where you can fold if overcards come and your opponent bets aggressively.

2. Early Position with AKo in a Cash Game at 100+ BBs

AK is a great hand. But at 100 BBs deep, shoving preflop with AKo turns a profitable hand into a marginal one. You’re either getting called by AA/KK (where you’re crushed) or getting everyone to fold (which wins you a small pot you could have won by just raising normally).

AK plays much better as a 4-bet/call or 4-bet/fold hand in deep-stacked spots. Save the shoves for when you’re short-stacked or when the dynamics demand it.

3. On the Bubble Without an ICM Advantage

ICM (Independent Chip Model) changes everything near the money bubble. A chip lost is worth more than a chip gained, which means marginal all-in spots that would be profitable in a chip-EV sense become losing plays in dollar-EV terms.

Classic example: you have 20 BBs and TT on the money bubble. Under normal circumstances, reshaving against a steal is easy. But if busting means losing $500 in equity and doubling up only gains $300 in equity, suddenly that 55% edge isn’t enough. The risk-reward is negative even though you’re mathematically favored.

This is where tools like proper bankroll management and understanding tournament stages become critical.

Multiway All-In Equity: How More Players Change Everything

The equity charts above are all heads-up. Once a third or fourth player enters the pot, even premium hands lose significant equity.

Scenario AA Equity Notes
AA vs 1 random hand 85.2% Massive favorite heads-up.
AA vs 2 random hands 73.4% Still great, but losing 12% equity.
AA vs 3 random hands 63.9% Down to roughly 2-in-3. Uncomfortable.
AA vs 4 random hands 55.9% Barely a favorite. You’ll lose almost half the time.
AA vs 8 random hands 35.1% AA is actually the underdog in a 9-way all-in.

This is why aces play best in raised pots with fewer opponents. If you just limp-call preflop and let five people see the flop, your aces are far more vulnerable than if you’d raised and gotten it heads-up.

Practical Scenario Breakdown

Scenario 1: Tournament, 12 BBs, You Have A9s on the Button

Everyone folds to you. The blinds are 1000/2000 with a 2000 ante. Pot is already 5000 before you act. You have 24,000 chips.

Shove. A9 suited has 57.5% equity against a typical big blind calling range (any pair, A2s+, A7o+, K9s+, KTo+, QJs). You’re risking 24,000 to win 5,000 uncontested — you only need folds about 83% of the time to profit purely from fold equity, and you’ll get folds more often than that from the blinds. When called, you still have decent equity.

Scenario 2: Cash Game, 100 BBs, You Have QQ, Facing a 3-Bet

You opened to 3 BBs from middle position. A tight regular 3-bets to 10 BBs from the cutoff.

4-bet to about 25 BBs. Don’t shove yet. If they 5-bet shove, you can call getting great odds. If they fold, you win 14 BBs. If they call, you play postflop with position disadvantage but a strong hand. Shoving 100 BBs over a 10 BB 3-bet turns a subtle strategic decision into a pure variance play.

Scenario 3: Tournament, 8 BBs, You Have 55 Under the Gun

Six players left at the table. You’re under the gun with pocket fives and 8 big blinds.

Shove. 55 has 44.7% equity against the range that calls you (typically 77+, ATs+, AJo+, KQs). But you also have fold equity — at a 6-handed table, everyone folding 70% of the time is realistic. The combination of fold equity + showdown equity makes this a profitable push. Waiting for a “better spot” at 8 BBs is how you blind down to nothing.

My Take: The Biggest Preflop All-In Mistake I See

After years of playing both live and online, the single biggest preflop all-in mistake I see — at every stakes level — is people not shoving wide enough when short-stacked. I watch players with 10 big blinds fold Q9 suited on the button, fold K8 offsuit in the cutoff, fold A3 offsuit in the hijack. They’re waiting for a “real hand.”

Here’s the thing: at 10 BBs, Q9 suited on the button is a slam-dunk shove. The math isn’t close. But people get emotionally attached to the idea of “going out with a good hand” rather than maximizing their tournament equity. They’d rather bust with AK than shove with K8o and win the blinds four times in a row to get back to a playable stack.

If you take one thing from this article, let it be this: your stack size dictates your strategy, not your feelings about what constitutes a “good hand.” A 10 BB stack turns K8o on the button into a premium holding. Respect the math. If you’re not sure about basic hand strength, check our hand rankings guide first — but the decision to shove is about stack depth and position, not just card quality.

Frequently Asked Questions

What is the win rate of pocket aces all-in preflop?

Pocket aces win approximately 85.2% of the time against a single random hand in an all-in preflop situation. Against a specific hand like KK, aces win about 81.9%. Against two random hands, equity drops to 73.4%, and it continues to decrease with each additional caller.

Should I always go all-in preflop with pocket aces?

In tournaments with under 30 BBs, almost always yes (after a raise or 3-bet). In deep-stacked cash games (100+ BBs), it depends. Shoving 200 BBs preflop with aces risks chasing away worse hands. A standard raise or 4-bet often extracts more value by keeping worse hands in the pot.

Is AK suited a good all-in hand preflop?

AKs is one of the best all-in hands. It has 46% equity against any pocket pair (a near coin flip) and dominates all other Ax and Kx hands at 70%+. In tournaments, AKs is a standard shove with 25 BBs or less. In cash games, it’s a good 4-bet/call hand but not always a direct open-shove.

How wide should I shove with 10 big blinds in a tournament?

From the button with 10 BBs: any pair, any ace, K2s+, K7o+, Q6s+, Q9o+, J8s+, JTo, T8s+, 98s, 87s. That’s approximately the top 35-40% of hands. From under the gun, tighten to roughly top 15%: pairs 22+, A2s+, A8o+, KTs+, KJo+, QJs.

What does “dominated” mean in preflop all-in situations?

A hand is dominated when it shares one card with the opponent’s hand but has a worse kicker. For example, AQ vs AK — both have an ace, but AQ’s queen is outranked by AK’s king. Dominated hands win only about 25-30% of the time, making them very unprofitable all-in matchups.

Does position matter for preflop all-in decisions?

Hugely. The later your position, the wider you can shove because fewer players remain to wake up with a strong hand. Shoving K9o under the gun at a 9-handed table is reckless; shoving K9o on the button is standard play with a short stack. The same hand goes from -EV to +EV purely based on position.
