Taking a weird line with AKs

[Harv72b]

Reads: I'm 3-tabling & my other two tables are both 6max, so the coldcall preflop was a semi-misclick. Anyway, this is my first orbit at the table, so I have no table image. UTG+1 is very LAGgy over ~50 observed hands: 40/20/4'ish. MP1 is pretty well unknown, but has looked a little loose but typical over ~20 hands. Button is a VPIP 75 calling station extraordinaire over the same 20 hands.

Preflop: Hero is MP2 with A[img]/images/graemlins/club.gif[/img], K[img]/images/graemlins/club.gif[/img].

UTG+1 checks, MP1 checks, Hero checks, Button checks.

Turn: (6.70 BB) 9[img]/images/graemlins/diamond.gif[/img] <font color="#0000FF">(4 players)</font>
<font color="#CC3333">UTG+1 bets</font>, MP1 folds, Hero calls, intending to see what the calling station does &amp; go from there

My intention is to fold immediately if Button raises, or call a bet from UTG+1 unimproved on a non-[img]/images/graemlins/diamond.gif[/img] river if Button folds. I'll flip a coin if Button flat calls the turn bet. How much do you hate it?
