Win, tie and loss for 55
When 55 and JTs get all in before the flop, 55 wins 47.6% of the time and JTs takes 52.4%. Broken down, 55 wins outright 47.2%, chops 0.8% and loses 52.0% — a margin of -4.8 points. Pair against two overcards — the classic coinflip, with the pair a shade ahead.
The same matchup shifts depending on how the suits overlap. With no shared suit the number is 47.5% (for example 5s 5h against Jd Td); with one shared suit it is 47.7% (5s 5h against Js Ts). That is a spread of 0.25 points across the 24 distinct card combinations, and it comes almost entirely from whether the two hands are fighting over the same flush.
Add a third player holding a random hand and the split becomes 55 34.3%, JTs 42.2%, random 23.6%. 55 gives up 13.3 points and JTs gives up 10.2, so the favourite loses more than the underdog does. Extra players always eat into the leader's share faster than into anyone else's.
Taken on their own, 55 is worth 60.3% against a random hand (rank 27 of 169) and JTs is worth 57.5% (rank 46). The gap between them in the ranking is only 2.8 points, yet head to head the gap is 4.8 points — a reminder that a ranking table and a direct matchup are two different questions.
Framed as a run of one hundred identical all-ins, 55 scoops roughly 47 pots, splits about one, and loses the remaining 52. Against eight random opponents rather than this one specific hand, 55 would be down to 13.2% and JTs to 18.1%, so the shape of this particular confrontation matters far more than either hand's standing in the overall ranking.
From JTs's side, 52.4% is the break-even point for calling an all-in at 0.91:1 pot odds. Put another way, the call is profitable as long as the amount you have to put in is less than 52.4% of the pot you are playing for. 55 holds the other 47.6% of that same pot.
Two caveats keep this figure honest. First, it is showdown equity across all 24 card combinations with five board cards still to come — there is no fold equity in it, so the value of shoving in practice is usually higher than the raw percentage suggests. Second, it assumes JTs really does hold exactly JTs; against the wider range a player would actually get all in with, 55's 47.6% moves.
