Maybe Stupid

I think the K is my cutoff for betting.

A Q or J and I like the check behind. For all the reasons Harv already stated.

EDIT: Having said that, I think there is value in raising the river with a Q or a J depending on number of callers.
ie. More callers, less times it has to be correct.

I haven't seen too many people willing to lay down a flush on the river after already putting in one bet.
A board flush would be magic.

i don't like it at all. they will call lots of hands here, lower hearts and the non TAG may call with any piece. You are losing bets here. And if you take it down now, then you take it down - the pot is fairly big at this point.
