how GM cognitively processes the chessboard.

After watching Magnus Carlsen play bullet, I find myself wondering how he cognitively processes the chessboard.

His decisions often seem to be made with virtually no visible thinking time.It seems unlikely that his perception is focused on individual pieces or isolated positions. Rather, he may be recognizing complex relationships between pieces—such as coverage, connections, tension, and potential threats—as structured patterns that can be accessed immediately.
This raises the question of to what extent these processes are based on learned pattern recognition, and how much they rely on automated, intuitive processing as opposed to conscious calculation of variations.
I would be interested in a more rigorous explanation, particularly from the perspective of cognitive science or chess expertise.

I think Magnus is over natural at chess. We simply can't figure out how players like him think in their mind
