Suited Connectors hit trips...

[strunks]

I have a note on Villain that says he goes too far with overcards, but it's a month old. He also seems to play a lot of hands.

Ultimate Bet No-Limit Hold'em, $.25 BB (9 handed) converter

BB ($4.75)
UTG ($15.20)
UTG+1 ($12.65)
Hero ($14.60)
MP2 ($31.50)
MP3 ($13.80)
CO :#A500AF(Villain)/ ($44.05)
Button ($27.20)
SB ($38.35)

Preflop: Hero is MP1 with 8[img]/images/graemlins/spade.gif[/img], 7[img]/images/graemlins/spade.gif[/img].
UTG calls $0.25, <font color="#666666">1 fold</font>, Hero calls $0.25, <font color="#666666">1 fold</font>, MP3 calls $0.25, CO :#A500AF(Villain)/ calls $0.25, <font color="#666666">1 fold</font>, SB completes, BB checks.

Flop: ($1.50) T[img]/images/graemlins/heart.gif[/img], 8[img]/images/graemlins/club.gif[/img], 8[img]/images/graemlins/heart.gif[/img] <font color="#0000FF">(6 players)</font>
SB checks, BB checks, UTG checks, <font color="#CC3333">Hero bets $1</font>, MP3 folds, Villain calls $1, SB folds, BB folds, UTG folds.

Turn: ($3.50) 9[img]/images/graemlins/spade.gif[/img] <font color="#0000FF">(2 players)</font>
<font color="#CC3333">Hero bets $3.5</font>, <font color="#CC3333">Villain raises to $7</font>, Hero ???

What's my move?
