ok so i have ~3.5K and a pretty aggressive table image.
i have been raising a lot of pots in position and either taking it down preflop or on the flop.
i'm pretty much bullying the table.

i'm in the BB w/ A4 and the villian in this hand is the button.
he is a decent player, who thinks he is better then he is.
i have him covered, i think he's got around 2K.

four players see the flop of A44 two diamonds.

all check to him, he bets $60, i call, all others fold.

turn comes a black 5.
i lead for $100, he calls rather quickly.

river comes 6 hearts.
i think for a second then bet $400.

comments on all streets appreciated.

ps. i know its not that exciting of a pot, and not that big either, but i'm just curious what line you guys think would have been optimal in this situation.
