50NL: Top set, villain bets into me with multiple straights on turn.

[Sean Fraley]

Villain has been at table for less than two orbits and caught every single hand, just about tripling up through a hyperlag donkey. I've been average TAG.

BTN: $60.10
SB: $55.60
BB: $147.45
UTG: $43.20
Hero (CO): $50

Pre-Flop: dealt to Hero (CO)
UTG folds, <font color="red">Hero raises to $2</font>, 2 folds, BB calls $1.50

Flop: ($4.25) (2 Players)
BB checks, <font color="red">Hero bets $3.55</font>, BB calls $3.55

Turn: ($11.35) (2 Players)
<font color="red">BB bets $7</font>, Hero ???

Basically all I know about villain so far is that he has seen a flop and wound up winning with some questionable hole cards. Everything else is a complete unknown. I would have to make about 7$ on the river to call for a boat. Should I do that, or is this a raise for value? Does anyone see a fold?
