As MIB211 stated, I'd go with a smaller turn sizing. I'd probably plan to go .5-.6Pot on turn and river.
As played, I think this is really close on fold/call. I made a range with as loose as I think V might be based on description. I put in 2 combos of 77 and 66 that might have decided to turn hand into a bluff OTR... not sure how often that happens. Also put in some NFDs.. not sure if those would have played the way they did...(oh & 2 ways for 87s)
With all of that, we come out w/ 37% equity. Drop out the 77/66 combos, and we're down to 27%... Unless we've been visibly leaking, this guy might not want to get into a reg-war with us making his ISO range more snug.
