Binion's Part 2

Blinds 100-200

My stack has been worked up to roughly 12500

UTG+2 limps, 2 behind the button limps, I am in the SB with , and I complete. I know, I know....bad. But I did it. BB checks.

Flop comes

Checks around.

This time, I stab at this rough board for 600, and I get called from UTG+2 (UTG+2 is easily the most aggressive player at the table.....and I have really been VERY active.....there was a point in Level 4 where he raised 5 consecutive hands preflop......haven't decided whether he is a really good player or if he is just hard to play against)

River card is a

I check.....UTG+2 bets out 1200.

Again....this is where I get stupid. Now, why is this guy leading out here? What could he possibly have that he is "value betting"? Diamonds missed, straight missed.....he limped in EP and didnt show any aggression until now. I'd probably just take it down if he hit the river.....Now I had given this pot up when he called the turn.....but I didnt expect this move at the pot from him....and it made my radar go off. I'm considering a raise here......

Have I lost my mind??
