[Lego05]

Villian is a 2+2'er: BlackIce781.

I have him at 17.69/13.51/3.85 postflop agg. over 1340 hands.
I've 4bet him twice at this table in like the last 10 or 15 minutes.

Preflop: Hero is SB with A[img]/images/graemlins/heart.gif[/img], A[img]/images/graemlins/club.gif[/img].
UTG calls $0.50, <font color="#666666">2 folds</font>, <font color="#CC3333">Hero raises to $2.5</font>, BB calls $2, UTG folds.


I check the flop cause...I believe his range here has to be almost only pocket pairs with maayybe some suited connectors. And I thought he'd fold a pocket pair if it didn't set up so I wanted to check call and go from there.

Hero checks, <font color="#CC3333">BB bets $4</font>, Hero calls $4.



Since I played it this way I thought he could be betting the turn again with a weaker hand.
