Just had a funny/annoying MTT which didn't last long.
I open from MP with KJ of clubs and a random player who i have no history with decides to 3bet me with K4 of spades - i call (good or bad call?). I pick up a open ended straight draw on the flop, he cbets, i call. I turn the nuts but now there are 2 spades on the board, he overshoves all in and i obviously snap call. River comes the ace of spades.
A few hands later, i shove my 10BB stack UTG with pockets 8's. The same guy reraises to isolate me and shows Q4. He hits the Q on the river, obviously.
Does anyone ever have these random players who seem to pick a fight with you and make these retarded plays for no reason? What's annoying is he sucked out both times. 
But yeah its never good to have an agro monkey to your left since he can make your life difficult.
