I was playing in the Candian Poker tour.I was sitting in the big blind position. The blinds were $500/$1500.There was a guy the champ from the last tournament to my right 1st to act.I got pocket J's/ He was the 1st to act he made it $5000 to go . everyone on the table folded including the small blind.I had about 20k in chips in frnt of me but I made the big mistake. Instead of just calling to see the flop I called all in. The champ called with his ace k and I lost toa ace on the flop.To me this was a mistake does anyone see this situation diffeent and my all in was the call?
