55 vs 33: Odds & Interactive Calculator

How 55 vs 33 unfolds by street

Pocket Fives (55) is still ahead on 89% of flops against 33, and the lead survives to the turn on 86%. 33 takes the lead on the other 11% of flops, almost always by flopping a set. These figures come from full board enumeration, not a simulation.

55 vs 33 is a pair-over-pair cooler — the kind of all-in nobody at the table can fold. 55 wins 80.1%, 33 wins 17.1%, and 2.8% of boards chop, a 4.7-to-1 edge for 55. With nothing but the case pair to chase, 33 is set-mining all-in: it wins about 1 in 6, correct to stack off preflop but a hand that hates a clean runout.

Think in variance terms: 81.5% equity means 55 loses this all-in nearly 19 times in 100, so even a "dominant" spot is a coin you'll see come up tails plenty. Getting it in as the 81.5% favorite is correct every time; the 18.5% that goes the other way is math, not a misplay.

As the bigger pair, 55, your whole job is to get the money in before a scare card — there's no fold here and slow-playing only lets 33 realize its set equity for free. As the smaller pair, the discipline is recognizing when stacks are deep enough that calling off 17.1% equity is a leak, even though folding pre feels impossible.

55 vs 33 FAQ

Who wins 55 vs 33 preflop?

55 (Pocket Fives) is the favorite, winning 80.1% of all runouts, while 33 (Pocket Threes) wins 17.1%. The remaining 2.8% are split pots. Counting splits as half, 55's preflop equity is 81.5%.

Does the 55 vs 33 probability change all-in preflop?

No. Once both hands are all-in preflop the odds are set by the cards alone — position, stack size and who bet first change nothing. The only thing that moves the number is suits: 55's equity runs from 80.8% to 82.2% depending on how many suits the two hands share, which is why different sites quote slightly different figures. It does change once board cards are dealt (55 leads on 89% of flops) and in multiway pots, where every extra caller takes equity from both hands.

Can you fold the smaller pair in 55 vs 33?

Almost never preflop all-in — but the 17.1% the smaller pair wins (about 1 in 6) means that when stacks are very deep and the action screams a bigger pair, laying it down is a real, if rare, fold. Set-mining the lower pair works only with the implied odds to win a full stack when you spike.

Does 55 hold up against 33 after the flop?

55 is still ahead on 89% of flops and stays ahead through the turn on 86% of boards; 33 takes the lead on the other 11% of flops. These are exact figures from full board enumeration.
