OK the river continuation bet was uncalled for, but I regret the way I played this. He figured his draw to the river was good at any cost, and hitting it cost me the tourney. Should I just have let him see it for cheap and if he failed tough luck, maybe betting 3000 on the turn? As it was I was out, should have been looking at 1st or 2nd, for 400 or 600 quid. As it was I walked out with 130, thanks to his outdraw.
