Foxwoods Tourney O/8 hand

[Nomar]

I have7k in chips, blinds 2-4

1 limper, cutoff raises SB calls, I call in BB with K833, K8 of diamonds (?????)...

Flop comes QQ5 checked around, turn 3, I bet, cutoff raises SB calls 2 cold, I 3 bet, cutoff caps, SB calls 2 more cold, I have 1400 left...and fold ?????

comments on all streets, would like more than fold preflop, I felt like I have a playing advantage over my opponets and in a 4 way pot I felt this hand was worth taking a flyer, chips average at this time was a lil under 6k, 28tables started, 8 left, 1500 starting chips
