88 and turn action

[sublime]

ok, so i am getting used to adjusting to the aggressive play on the party 15. here is a situation that i didnt know how to react to. all comments appreciated.

UTG2- at the time basically unknown. i checked his stats right quick when he raised on the turn, but i didnt have a decent amount of hands to draw a conclusion, so assume a stranger.

CO is a stranger

SB is a LAG. both pre and post flop

BB is a stranger also.

Party Poker 15/30 Hold'em (10 handed)

SB checks, <font color="CC3333">BB bets</font>, <font color="CC3333">UTG+2 raises</font>, <font color="CC3333">Hero???

EDIT: looking at it, it seems like a raise. what if your notes say the guy is loose/passive pre and post?
