So I had the best hand, but the betting indicated two pair, trips or a made straight, so folding was good. In any event, I was lucky enough to double through a couple of hands later when I flopped a royal flush(!), slowplayed for a big pay-off and eventually won the tournament, so with hindsight I was happy.
