Is that really what he found? As far as I remember they were no better in
*memorizing positions* than an amateur when it came to random positions.
They would still perform better when playing them. I also doubt professonals
on average don't read faster, both in Go and in Chess. I'm pretty sure they
do in Go. That doesn't mean they always read a lot though.

Professionals definitely 'see more' in a Go position than an amateur does.
'See more' in the sense that they see more things that are relevant to
winning the game.
