Hitting my trips would have given lasvegas4 a straight, so really I needed the kings to pair or to catch 2 running pair (counterfeiting his 2 pair). The only thing I can think is I should have pushed more than 5bb pre-flop, but I don't like to reveal the true strength of my hand. Maybe I just got unlucky?
