......and his call PFR was what?

here i don't believe he is folding an ace, or a set (77, 88 or 99 are all in his range). actually 78, 79 and 89 are there too.

with your monster draw i would call his turn bet, then get it in if you hit the river.

i doubt he is triple barelling you here w/o a hand that has you beat, so you can fold to a river bet

it's a situation where you are stacking him if you hit almost every time, but you can save $160 when you miss
