Yesterday I was playing a 45 seat sng.I was @ the final table sitting with 16k in 1st place.I was in the bb and woke up with pocket jjs.Everyone folded around and the sb sitting with 13k moved all in.I thought it out figured I probably did have the best hand but decided most likely I would be in a race situation and decided to fold.I didnt want to risk almost all of my stack that late in the tourny.I had just transferred to the ft and I didnt know this player and if he was just moving on the pot.The blinds were 400 800.I showed my jjs and the whole table thought I made a bad decision and that I should have called.I was getting donk faces from everyone.Just wanted to see what you guys thought and to get some feedback.I finished second and I lost to that same player that I was up against with the jjs.I asked him what he had when we were hu but he would not tell me.I regreted not calling.
