Win, tie and loss for 66
When 66 and KQo get all in before the flop, 66 wins 53.4% of the time and KQo takes 46.6%. Broken down, 66 wins outright 53.2%, chops 0.4% and loses 46.4% — a margin of 6.8 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 both suits shared the number is 53.1% (for example 6s 6h against Ks Qh); with no shared suit it is 53.9% (6s 6h against Kd Qc). That is a spread of 0.83 points across the 72 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 66 38.9%, KQo 39.3%, random 21.8%. 66 gives up 14.6 points and KQo gives up 7.3, 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, 66 is worth 63.3% against a random hand (rank 17 of 169) and KQo is worth 61.5% (rank 23). The gap between them in the ranking is only 1.8 points, yet head to head the gap is 6.8 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, 66 scoops roughly 53 pots, splits about one, and loses the remaining 46. Against eight random opponents rather than this one specific hand, 66 would be down to 13.7% and KQo to 16.7%, so the shape of this particular confrontation matters far more than either hand's standing in the overall ranking.
From KQo's side, 46.6% is the break-even point for calling an all-in at 1.15:1 pot odds. Put another way, the call is profitable as long as the amount you have to put in is less than 46.6% of the pot you are playing for. 66 holds the other 53.4% of that same pot.
Two caveats keep this figure honest. First, it is showdown equity across all 72 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 KQo really does hold exactly KQo; against the wider range a player would actually get all in with, 66's 53.4% moves.
