Yeah I've heard this description too, and it makes sense. But I also get the sense that the "chunks" must not just be simplifications of parts of the board, in fact the experts must "see more at once" than the newbie right? Like inside of the chunks there is somehow tons of intricate detail that the newbies can't even see, let alone assimilate into one memory or instinct or thought.

Maybe like a tourist who notices one interesting building or sign. The local doesn't notice anything, just like "cool, I remember this place," except then they notice if one small detail changes compared to the last time they visited. So in a sense they "saw" way more than the tourist.

I am also terrible at chess. Curious if this is anything like how the experts experience it.
