Hero ?

c/c probably

...just looked at your sig too, lol ISF has come a long way.

i think c/c. dont bet, let him bluff.

Check the river but really pay attention to the timing on this one. Hopefully you can pick some tell up. Personally i think fast bet here is probably trips while longer is probably a bruff.
