Fascinating topic John,
Nothing to add on the Westerns side, not my thing.
But on the golf side, as a highcapper, I was often the one getting 2, 3, even 5 strokes or more per round. I found the easiest holes to win were often the hardest ones on the course. Opponent tries for miracle shots, but I would play conservative, get a relatively easy bogey, net par, and won the hole far more often than I lost.
