Donkey Kong....or Donkey Call?

On the heels of the big year-end tournament win by the common man.......I find myself still pondering back-back calls by Mad Mike and Stuie. Blinds are 50/100 and in dealer position, I fire out 600 chips pre-flop sitting on pocket Jacks. Mad Mike calls with A/2 offsuit.......huh? Stuie claims he knew Mike had an Ace, but calls with A/4 offsuit....what? An argument could be made that he was priced in.. If he truly thought that Mike had an Ace though.....did he really feel confident his 4 would hold up? Pre-flop odds put Mike at 7.14% to win....Stuie at 9.44%.....and Negreanu at 72.7%. Naturally an Ace hits the board and Negreanu is tilted by the questionable play. Donkey Calls..................
