It is the place where the Masters has been won and lost over and over again. Amen Corner was where Coody grabbed the first-round lead, shooting two under through the stretch, on the way to his opening 66. But Player and Palmer went two over there, and Casper and Nicklaus one over, Jack by trying to slam a one-iron onto the 13th green. He went into the creek and suffered one of the three penalty shots he strapped on himself during the tournaments. Three penalty shots, and he lost to Coody by two strokes.
Nobody has any idea what pressure there is.
You wait months for a Masters or an Open, and then when it comes you feel every single shot is the one that'll win it or lose it for you. You find yourself making mistakes you wouldn't ordinarily make, and also doing things well that you might not otherwise do. You're so charged up it's a constant fight. It's the magnitude of the mistakes that kills you. Nicklaus was the only member of the Big Four who was a driving force, and Coody said he felt sorry about Jack and the Slam.
