TT vs 66: Odds & Interactive Calculator

How TT vs 66 unfolds by street

Pocket Tens (TT) is still ahead on 89% of flops against 66, and the lead survives to the turn on 85%. 66 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.

TT vs 66 is a pair-over-pair cooler — the kind of all-in nobody at the table can fold. TT wins 80.7%, 66 wins 18.8%, and 0.5% of boards chop, a 4.3-to-1 edge for TT. With nothing but the case pair to chase, 66 is set-mining all-in: it wins about 1 in 5, correct to stack off preflop but a hand that hates a clean runout.

Think in variance terms: 80.9% equity means TT 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 80.9% favorite is correct every time; the 19.1% that goes the other way is math, not a misplay.

As the bigger pair, TT, your whole job is to get the money in before a scare card — there's no fold here and slow-playing only lets 66 realize its set equity for free. As the smaller pair, the discipline is recognizing when stacks are deep enough that calling off 18.8% equity is a leak, even though folding pre feels impossible.

TT vs 66 FAQ

Who wins TT vs 66 preflop?

TT (Pocket Tens) is the favorite, winning 80.7% of all runouts, while 66 (Pocket Sixes) wins 18.8%. The remaining 0.5% are split pots. Counting splits as half, TT's preflop equity is 80.9%.

Does the TT vs 66 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: TT's equity runs from 80.3% to 81.6% 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 (TT 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 TT vs 66?

Almost never preflop all-in — but the 18.8% the smaller pair wins (about 1 in 5) 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 TT hold up against 66 after the flop?

TT is still ahead on 89% of flops and stays ahead through the turn on 85% of boards; 66 takes the lead on the other 11% of flops. These are exact figures from full board enumeration.
