ok I think I see your point. If his range is ONLY flush draws and we know he will bluff the river 100% of the time when he misses, we should call the turn raise and check/call a nonspade river and check/fold the rest. That is true.

EDIT: Wait. No it's not...why wouldn't we just 3bet the turn and check/call a nonspade river and check/fold a spade. Wouldn't he bluff here too if he'd bluff 100% in the other situaiton? lol. We'd make more this way.
