That's sort of the point, isn't it? To let worse hands bet into us. Also we save a lot against KQ, possibly getting a free showdown/possibility to take the pot away should a heart hit on the river.

The flop/turn action suggests a flushdraw as the most likely hand (would KQ check call on a twoflush board?), I don't know if he bluffs it on the river often enough to make a check behind profitable.
