No real reads, BB is fairly new to table. I was sitting out and missed the hand he doubled up on:

Full Tilt No-Limit Hold'em, $0.50 BB (5 handed) Hand History Converter Tool from FlopTurnRiver.com (Format: FlopTurnRiver)

saw flop|saw showdown

Button ($44.85)
SB ($13.65)
BB ($97.90)
Hero ($59.30)
MP ($10)

Preflop: Hero is UTG with T, T.
Hero raises to $2.25, MP calls $1.75, 1 fold, SB calls $2, BB raises to $6.5, Hero ???
