While creating this page, it came to me that this is actually quite reassuring for the experienced player. If they say that pros see 1000 moves at once, compared to us, the above discussion shows that strictly speaking, we see 720 moves at once, compared to beginners! --Dieter
ilan: From my observation, I conclude that a difference between strong amateurs and strong professionals is that amateurs do not consider every move, and, in particular, completely ignore possibly weak or irrelevant moves during analysis. For example, Michael Redmond's book The ABC's of Attack and Defense is a book which really goes into dirty details of moves which would occur to weak players like me because we don't know enough not to worry about them.

[1] Gronk: Sorry, I must not be reading this right. Professionals consider every move, even clearly weak or irrelevant ones that amateurs do not consider? That's a lot of stupid moves for a professional to consider, since there are likely vastly more dumb moves than smart ones. It sounds like amateurs who completely ignore possibly weak or irrelevant moves are doing something quite smart that professionals might do well to adopt. ilan must be a professional since he learned something about moves he should have ignored from The ABC's of Attack and Defense (i.e., he wasn't already ignoring them the way he says amateurs do and professionals do not).
