How much thoughts (of course, your current rally related) go through your mind during a rally? Do you plan your course of tactics, e.g. the first 2-3 shot likely exchanges + a contingency? Are those really thoughts? As some chess coaches say, when you play chess, it's more like pattern recognition (looking for tactics) than thinking. So are you really doing thinking or pattern recognition. And if you look up some Tennis/Golf/Martial Arts reference materials on Mental, they'd say something like - "no mind", "clear your mind", "Self 1 should let self 2 do its job", etc in order to perceive things and thus act/react faster. So which one is it? Comments?
