Bernard Darwin, “Walter Hagen” in The Darwin Sketchbook (Writings from 1910 to 1958)

“That Hagen had an overpowering effect in match play on some of his opponents was clear enough. His demeanour towards them, though entirely correct, had yet a certain suppressed truculence; he exhibited so supreme a confidence that they could not get it out of their minds and could not live against it. They felt him to be a killer and could not resist being killed. He had a very shrewd eye for their weaknesses and, strictly within the limits of what was honest and permissible, he would now and then exploit [it] to his own advantage.”
