A8o against a SH (ex)-pro. What line do I take?

(comments appreciated on this, please)

I like either 4 betting the flop...if he calls, lead the turn, check the river. If he 5 bets, call the turn, and Im torn between calling/raising his river bet (Id probably raise).

Or call the 3bet, call the turn, rasise the river.

Dunno, thats three lines Im tossing around, but I really like the first two.
