Pseudo-interesting turn decision

[mcvalenc]

Button is 31/25/1.5 in 2000 hands
MP is 59/20/1.8 in 750 hands

No reads, it's my 1st hand at the table.

Preflop: Hero is BB with 8[img]/images/graemlins/spade.gif[/img], A[img]/images/graemlins/spade.gif[/img].
<font color="#666666">1 fold</font>, MP calls, <font color="#CC3333">Button raises</font>, <font color="#666666">1 fold</font>, Hero calls, MP calls.

Flop: (6.50 SB) T[img]/images/graemlins/club.gif[/img], 7[img]/images/graemlins/club.gif[/img], 5[img]/images/graemlins/diamond.gif[/img] <font color="#0000FF">(4 players)</font>
Hero checks, MP checks, Button checks.

Turn: (3.25 BB) A[img]/images/graemlins/diamond.gif[/img] <font color="#0000FF">(4 players)</font>
So what's my plan? Check-call, bet-fold or bet-call?
