Poker Tourament @ Holiday Inn 4/7

Just did the $30 buy in tourament at the Holiday Inn. I accumulated about 8000 in chips when someone with a much larger stack was moved to our table. I made it 3000 with J c J h and he called and the flop came KQ6 all hearts, and he moved all in. I called, but I didnt quite realize I was a 60/40 underdog. This was a clear mistake. My logic was that if the heart came, I would have 16000 in chips, and probably the chip leader for the entire room and I would coast into the money. Somehow this coasting never seems to happen...My dad and Rocky made the final table, busting out on the bubble in 7th and 8th respectively.
