no hand history sorry. villain is pretty new at the table, but has been splashing about quite a bit. i have been splashing about alot and have been doing pretty well. effective stacks of $30. i am UTG

hero has QQQ rag rag
hero raises to $1.50
folded to villain on the button, who raises to $4
hero calls
hero draws 2
villain draws 2
my hand fails to improve and is now QQQT3
hero checks
villain shoves

wtf?

is this always a full house? is this always a bluff? any guesses as to what villain has?
