I suppose "worst" it subjective. I much prefer to get crushed by a better player say 6-1 than to an opponent at my level by two points in a TB. Why? It means, had I converted just two shots, I would have won -- but failed. In your case choking a few times is quite frustrating and that's why you're here.
