I call the turn raise and checkraise any non-Ten river. Your turn 3-bet will fold him if he's on air, but he'll generally fire again on the river with air if you just call. He's always raising the turn with 7x, but might not 3-bet the river if a scare card comes (like a 3rd flush card), so you sometimes save yourself a bet.

However, when the Ace comes on the river I like your lead because it's the one card that might convince him to check behind. The fold seems OK when he raises, although I'm generally calling this.
