So my first answer was to call. Then I did the math:
25/81.9 = 30.5% equity needed for call to be breakeven

PokerStove is giving me 40% equity vs. villains range.

88-1 combo - lose
66-3 combos - lose
K8-6 combos - lose
K6-9 combos - lose
Q8-4 combos - split
Q6-6 combos - win
68-6 combos - win

So if I did everything correct I come up with 19 combos that we lose against and 12 we win and 4 we tie.
