Collussion? Tips? Teamates?

[hotkelly]

I won't name names, however, i'd love to.
2000 NL game on Party last night.
1 raiser to 100 preflop.
4 callers of 100 including me.
Hero has Ah Qh
Flop 2h 3h 7h
Villain in the Big Blind fires bet of 333 into 400 pot.
Having the nut flush I raise all in.
Villain calls and pairs up to make a full house of 333 over 22. Tell me this is not a tip to the other players, including the raiser that he has a set of 3's? A bet of 333 is so obvious its sick.. I'd like your thoughts on the logic behind this bet of 333. Collusion at its finest? I know there is fishy stuff going on at the 2000 NL game.. your thoughts here? Thanks - Hotkelly
