This post by Allen Fox talks about how Roger handled choking by not panicking.
I should add that if there was anything to learn from this match it was that you can choke and still win as long as you don’t get rattled about it. And the topic of “courage” comes up when people think about choking. In my opinion, it doesn’t show courage to not be nervous and make the big shot on the big point. It takes courage to choke on the big point, not get upset about it; fight your way to another big point; and finally come through, either by making a good shot or your opponent missing.Fox's point can apply to other situations beyond sports. That it's OK to tighten up under pressure as long as you recognize it and keep trying to do your best.
