Why I call: His turn raise is representing a six. The river completes backdoor straight and flush hands. However, most people wouldn't semibluff raise on turn, especially given chip stacks here so likely he either has a made hand(w/ an 8?) or is bluffing. Additionally, on river he makes a big bet on board where both backdoors came in. Though it's not a superthin value bet, it is a gutsy value bet nonetheless and most people don't make these thinnish value bets, being content to check down their good hand. my 2 cents. Thus likely a bluff.
