Out of curiosity: are there any known blind chess players? I guess it would be quite hardcore.
In the biannual international chess 'olympiads' (team competition between countries) a multi country blind players team competes. Some other disabilities are also represented in the same way.
"Are there any blind chess masters in the world? Have there been any throughout history? Yes. Al Sandrin, who died a few years ago, was an USBCA member who was a master." [2]
