Flush draw vs top pair: the odds

What are the odds of a flush draw against top pair on the flop?

Hand Cards Wins Equity
Nut flush draw A♥ 9♥ 44.9% 44.9%
Top pair K♦ Q♣ 55.1% 55.1%
Split pot 0.00%

On a K♥ 7♥ 2♣ flop, with two cards to come. Equity is each hand's average share of the pot — outright wins plus half of the split pots. Computed by enumerating all 990 possible boards with this site's own engine, so these are exact figures rather than a simulation.

Why the number looks like that

Nine cards complete the flush, worth roughly 35% by the river — and here the ace is a second way to win. This is why a flush draw can call a big bet on the flop and cannot on the turn: the same nine outs are worth half as much with one card to come.
