This question reminds me of an experience I had in the first World Open I ever went to. I was in the huge D section, near the bottom. As I looked around at my potential opponents, there was a cute little girl of about 12 in a wheelchair. And there was an elderly gentleman who was blind.
My first thought was, "Please, God, don't let me play either one!" I could just hear my friends back hope when I reported my performance: "Oh, yeah, I beat a cute little girl in a wheelchair and an elderly blind man." Or, possibly worse: "I was beaten by a cute little girl in a wheelchair and an elderly blind man."
Not knowing that chess sharks come in all shapes, sizes, ages, and degrees of physical ability, they'd think me either a player of monstrous cruelty or a hopeless dweeb with no more chess ability than a schnauzer.
Thankfully, I never played either one.
I'd normally acquiesce to the blind players beating me in less than 50 moves ... but more than 50?
That, my good sir, is simply an outrage.
I would tie up their beloved family pet and make them watch ... no wait. That doesn't work.
