Aphantasia in chess
It is the ability to mentally picture things. That seems the most natural thing in the world, but some people are unable to do it at all. They cannot imagine a sunset, see any vivid details, vibrant colours, in their minds. Or they may only produce a mental image that is blurry and lacks detail. Michael Bacon, the Armchair Warrior, is a USCF Expert with aphantasia. He has written about how the condition relates to chess. | Image Credit: Andrew Mason
