I raise out of the SB to ensure the BB drops (I know, too "basic"). Once you don't, I like the flop and turn but I'm checking the river. It's too likely he has a hand with the nut spade in it and I hate getting raised here. Plus if he has say, red aces or some kinda overpair sans spade, he may stab at the pot or not call if you bet. But the way he played it with all that splashing seems like a big spade with a pair. When he raises the turn, he either has a big pair with spade backup or a big pair w/o it and doesn't want to risk giving you a cheap look. With the spade, he raises the end...without it, he may bluff when you check since the pot is so big and may not call if you bet (particulary if he has something like JJ red).
