Who played this worse?

[budman]

20-40 Hold'em at Foxwoods Friday Night. Game has been loose pre-flop. Stable pro just sat down and is now the button (posted after the button).

I am large blind with Ah9c. Five limpers to the button, who raises. Small blind folds everyone else calls. Seven of us to the flop (7.5 big bets).

Flop comes Ad - 10h - 9s. I bet out with top and bottom pair, someone downstream raises, button three bets, I cap. Four of us to the turn (16.5 big bets).

Turn is 7h. Board now reads Ad, 10h, 9s, 7h. I bet out, get one fold, one call and button raises. I three-bet, and both call (25.5 big bets).

River is Kh. I check, middle players checks, button bets. I call, middle player overcalls (28.5 big bets).
