Suited vs offsuit: JT

How 55 vs JT unfolds by street

Jack-Ten (JT) is still ahead on 43% of flops against 55, and the lead survives to the turn on 42%. 55 takes the lead on the other 57% of flops. These figures come from full board enumeration, not a simulation.

55 vs JT is the classic preflop race — a pocket pair against two overcards (connected overcards). Here the overcards actually edge in front: JT wins 50.2%, 55 wins 49.0%, and 0.8% of boards chop. The unpaired hand has six outs twice over (any Jack or Ten), and with its straight gappers live too the whole thing sits within a few points of a coin flip.

Think in variance terms: 50.6% equity means JT loses this all-in nearly 49 times in 100, so even a "dominant" spot is a coin you'll see come up tails plenty. Getting it in as the 50.6% favorite is correct every time; the 49.4% that goes the other way is math, not a misplay.

Practically, treat 55 vs JT as a flip: get the money in when you have fold equity or a tournament reason to gamble, and don't agonize over who's "ahead" — the edge is too small to fold a hand you've committed to. The mistake isn't taking this race, it's taking it for a deep stack with no dead money in the pot.

55 vs JT FAQ

Who wins 55 vs JT preflop?

It is close to a coin flip: JT (Jack-Ten) has the slight edge, winning 50.2% of all runouts to 55's 49.0%. The remaining 0.8% are split pots. Counting splits as half, 55's preflop equity is 49.4%.

Does the 55 vs JT 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 47.5% to 50.4% depending on suitedness and which suits the two hands share, which is why different sites quote slightly different figures. It does change once board cards are dealt (JT leads on 43% of flops) and in multiway pots, where every extra caller takes equity from both hands.

Should you call all-in with 55 against JT?

55 vs JT is close to a coin flip (49.0% vs 50.2%), so calling off is correct whenever the pot is laying you a price near even money or you have a tournament reason to gamble. Deep-stacked with no dead money, it's a thinner spot — the edge is too small to commit a big stack without fold equity.

Does JT hold up against 55 after the flop?

JT is still ahead on 43% of flops and stays ahead through the turn on 42% of boards; 55 takes the lead on the other 57% of flops. These are exact figures from full board enumeration.
