The river is out. Three hearts are on the board, so any two hearts in their hand make a flush.

the count

flushes they can hold = C(hearts left, 2)

C(10, 2) = 45 · holding one heart: C(9, 2) = 36

Every card you hold is a card they can’t.

use it

Bluff with cards that block their best calls. Call with cards that block their value, not their bluffs.
