NL5?10? River set, 4 to flush on board?

[vixticator]

Button is 60/2/1.7 through 55.

I have no idea what to do on river. B/C? B/F? C/C? C/F?

Betting the river seems pretty terrible here. Would you bet the river with a 2h? A heart seems his most likely hand. I probably give up to any reasonable bet.

Bet about 2, fold to a raise?
