A Preflop Situation

[mc123]

Your in the SB in a 10 handed game with AJo.

Unknown new player posts 3 off the button with a 12.21 BB stack in the Party game which is 25 BB default buyin.

BB is a 54.8 VPIP, 3.2 PFR player over the last 60 hands at the table and his AGR is 0.31/0.38/0.67.. at the rate he's playing right now he's losing 20BB per 100 hands.

Folded to unknown and he raises immediately, your plans preflop? your plans on a ragg board?

Edit: BB has never coldcalled 2bets preflop on the table yet.
