ipoker 200bb i bluff arrrinn

[bmxicle]

op is a 19/16/3 who has been three betting me fairly frequently. I four bet bluffed him and folded once, but other then that i've just been letting him three bet me a fair amount. I can remember from other days that horrible attempts at floating were always met by a second barrel, so he can be bluffing here imo, but its still obv not clear cut. Thoughts?
