early 11$ KK

Hi, I had this hand at a 11$ SNG on Betsson (Pokerroom).. what do you guys think?
I had [Kh][Ks]

Seat 1: mehdy2 ($1,390 in chips)
Seat 2: WeeFatShug. ($1,450 in chips)
Seat 3: VerticalMind ($1,500 in chips)
Seat 4: LalleLalle ($1,615 in chips)
Seat 5: dr. tim ($1,470 in chips)
Seat 6: SUMRAY ($2,290 in chips)
Seat 7: stagg248 ($1,280 in chips)
Seat 8: Phlipil ($1,595 in chips)
Seat 9: synergie2005 ($1,480 in chips)
Seat 10: uffe_82 ($930 in chips)

ANTES/BLINDS
SUMRAY posts blind ($10), stagg248 posts blind ($20).

PRE-FLOP
Phlipil folds, synergie2005 calls $20, uffe_82 calls $20, mehdy2 calls $20, WeeFatShug. folds, VerticalMind folds, LalleLalle bets $150, dr. tim folds, SUMRAY folds, stagg248 folds, synergie2005 calls $130, uffe_82 calls $130, mehdy2 folds.

FLOP [8c,8h,3h]
synergie2005 bets $250, uffe_82 folds, LalleLalle bets $700, synergie2005 bets $1,080 and is all-in

These 11$ SNGs are (as you know) extremely loose, therefore the large bet preflop.

What do you think of my flop play?
Should I lay this one down or call?

Thanks!
