AA fold?

[orange]

hero just got at table. opening villan is loose and is on alot of my tables. other guy (BTN) no idea.

200nl 6max. effective $200. no real reads.

PF: MP opens $7, I call with A[img]/images/graemlins/spade.gif[/img]A[img]/images/graemlins/heart.gif[/img] in CO, BTN calls $6. all others fold.

($23) Flop: 7[img]/images/graemlins/spade.gif[/img]3[img]/images/graemlins/spade.gif[/img]7[img]/images/graemlins/heart.gif[/img]
MP bets $20, i raise to $67, BTN shoves AI ($193), MP calls $193, I have to call $120 in like a huge pot. eh?

i would put MP on an overpair a ton, BTN i have no clue. maybe a 7? sometimes a fd? easy dump given action?
