Bad Bets, pt. 1

Pushed in half my chips with JJ after the board was all undercards. I figured I had seen pocket aces only two hands prior and I could probably push someone out with the unlikely QQ or KK because they might think I hit trips and their pot odds were sort of crushed by my big, smart, play. Unfortunately he pushed all-in. I looked at him. He crouched in his chair and scrunched up his nose, strength was coming off him in waves BUT this is why I shouldn't play poker: I called. ACES!!! Not again!
