Interesting hand between me and another 2+2

[Sykes]

Situation: Live $1/$2 game at the local casino.

He's been running pretty bad, although his play up to now is quite fine. He's read SSHE and applies it quite well. Basically a TAG in all aspects.

I've been running good, not showing down many hands, and when I do show them, I have the nuts.

Folds to me in MP1, I raise with AQo
He re-raises in MP2,
Donk caps in MP3.

rest fold.

Flop is 8 high.

Check to him, he bets, donk calls, I call.

Turn is 9.

Check around.

River is a rag.

I bet.
