AND I WON THE FREAKIN' POT!!!

Oh, and by the way...I suck..

Stack sizes:
UTG: $900
UTG+1: $1036
MP1: $1000
MP2: $2191.25
MP3: $1000
CO: $2551.50
TripleB: $2470.15
SB: $1846
BB: $992.40

Pre-flop: (9 players) TripleB is Button with
5 folds, CO raises to $40, TripleB raises to $140, 2 folds, CO calls.

Flop: ($295, 2 players)
CO checks, TripleB bets $180, CO calls.

Dream flop and we both have 2.5 stacks. Did I mention 2.5 stacks? And did I mention DREAM FREAKIN' FLOP!?!?!

Turn: ($655, 2 players)
CO checks, TripleB checks.

I figure I have the deck pretty well crippled here, plus I'm basically unbeatable, so I check. WHY? WHY? WHY? Oh, did I ask WHY?

River: ($655, 2 players)
CO checks, TripleB bets $400, CO folds.
Uncalled bets: $400 returned to TripleB.

It looks harmless, but this card is the poker gods beating me down with only a small amount of mercy, since I did still win the pot.

Results:
Final pot: $655

Can anyone see why this makes me cry?

P.S. I need a hug

Did Villian have 77 and the 10 counterfits his set?? He could have been trying to check raise the turn except you have to bet to let him check raise.
