WSOP ME hand, biggest hand I ran into... analysis greatly urged

[Jurollo]

Blinds 100/200 ante 25 (Level 4)
1,250 or so left in the day 1a field

Stacks
My stack: approx T8000
MP2 stack: approx T20000
BB stack: approx T15000

Fairly weak passive table except for a few good players. Limps are generally good enough to see a flop. MP2 just sat around 30 mins ago and has raised when he has played, very little limping, he is also big stack at table.

I see 8 [img]/images/graemlins/club.gif[/img] 7 [img]/images/graemlins/club.gif[/img] UTG and limp, folded to MP2 who makes it T650 to go. Folded to BB who calls for T450, I think and call. I have a tight image at the table and have generally played solid all tourney.

POT: T2200
FLOP T [img]/images/graemlins/club.gif[/img] 7 [img]/images/graemlins/spade.gif[/img] 4 [img]/images/graemlins/club.gif[/img]
BB checks, I bet T1500, MP2 looks at me and raises to T3600 total. So T2100 more for me to call, and I have about T6000 left in front of me. I think about it and push. He calls. I say "You got overs but I am the favorite".

Results

He shows Qd Qs and takes down the pot</font>

Thoughts?
