but you are so predictable, because you always put up 1 (US) or 2 (UK) fingers to my posts.
Of more relevance to the original question, is whether you can, by studying the writings of experts, learn to understand better than you could purely by introspection (or by playing with yourself); your thought experiment illustration demonstrates that your subjective impression of your personal volition is contradicted by objective scientific investigation.
Yes, it's better to think something through, and you can consciously choose to exercise your (imaginary) free will to think - but the thinking itself is subconscious - you only become aware of its results after it has happened.
Have you ever made a move in Go and been unable to explain why you did it? It happened to Haylee:

PS re-reading the above, i see it's not a satisfactory answer, because it doesn't adequately explain either the phenomenon of consciousness or the subjective experience of free will.
Both are subjects for which science still does not have clear and simple explanations, unlike the simplicity of the theory of, say, quantum mechanics!
But in any case, as far as learning Go is concerned, they are side issues, since we can't do anything about them, whether or not we subscribe to this or that theory of them - although they do have significant implications for the purposes and methods of jurisprudence.
In my videos about mental imagery in Go, i frequently use the analogy of the mind as an iceberg, with the notion that conscious reasoning is the little bit above the surface and subconscious (conditioned) intuition the greater part below.
However, i am starting to think that that image is inaccurate, and that the relative size of the conscious mind is more like the mere tip, and that even reasoning is done subconsciously.
Be that as it may, it doesn't really help to resolve the issue of theory vs practice.... but maybe there is a simpler answer:
you need both!
Carlos Santana says he is a self-taught musician, but maybe that only makes him even more extraordinarily brilliant.
