this hand is very read-dependent. one of the reads i put on people is how they play AAxx. comments by street.

pre-flop: i don't find raising out of the sb is usually a good idea, but that's my style. there are times to do it, but i'm not sure this is one of them. btw, what position is villain in?

flop: if villain plays fit or fold, then a bluff on the flop and maybe a second barrel on the turn will take care of things. that being said, many people WILL NOT FOLD ACES. furthermore, your bet looks suspiciously like a steal. why not check to the pf 3-bettor? i know there are reasons, but have you established enough a table image with this players so this doesn't look so obvious? also, if you were in sb, how did villain check to you (on all streets, no less)?

also, as a general rule, do you bet 2/3 pot with a decent range of hands? i usually don't although this type of flop and turn might justify it (i.e., villain is usually wa/wb, so pricing out draws isn't so necessary). another read to get is whether villain sees non-pot bets as bluffs. i love these people when i can find them.

turn: ok... most same issues as flop. board looks scarier for villain unless he picked up a draw or two (e.g., str8+fl).

river: well, if you think the 3rd barrel will do it, go for it. villan's getting a pretty good price, and this is esp. true if he had a K or maybe a 9.

conclusion: i generally don't like to run these kinds of big naked bluffs unless i know villain is prone to folding without a big hand. if that's the case, then usually the 3rd barrel is a spew since he's basically saying that he has a hand (probably AAxx he can't fold, AA9x, or maybe AAKx) that he'll call the smallish river bet with.

if this guy has AAxx, then you're better off just marking him as one of those guys to value bet to death with a relatively wide range. at the 100s, i find that these types of players are plentiful.
