Win, tie and loss for 77

Win 80.6%Lose 18.0%

When 77 and 33 get all in before the flop, 77 wins 81.3% of the time and 33 takes 18.7%. Broken down, 77 wins outright 80.6%, chops 1.4% and loses 18.0% — a margin of 62.6 points. Pair over pair — the higher pair is roughly an 80/20 favourite.

The same matchup shifts depending on how the suits overlap. With no shared suit the number is 80.6% (for example 7s 7h against 3d 3c); with both suits shared it is 82.1% (7s 7h against 3s 3h). That is a spread of 1.46 points across the 36 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 77 53.9%, 33 16.8%, random 29.3%. 77 gives up 27.4 points and 33 gives up 1.9, 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, 77 is worth 66.3% against a random hand (rank 9 of 169) and 33 is worth 53.7% (rank 67). The gap between them in the ranking is only 12.6 points, yet head to head the gap is 62.6 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, 77 scoops roughly 81 pots, splits about 1, and loses the remaining 18. Against eight random opponents rather than this one specific hand, 77 would be down to 14.6% and 33 to 12.8%, so the shape of this particular confrontation matters far more than either hand's standing in the overall ranking.

From 33's side, 18.7% is the break-even point for calling an all-in at 4.35:1 pot odds. Put another way, the call is profitable as long as the amount you have to put in is less than 18.7% of the pot you are playing for. 77 holds the other 81.3% of that same pot.

Two caveats keep this figure honest. First, it is showdown equity across all 36 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 33 really does hold exactly 33; against the wider range a player would actually get all in with, 77's 81.3% moves. Use the individual pages for 77 and 33 to see how each of them fares against all 168 other holdings before treating this single pairing as the whole picture.
