I know that the topic of Rachmininoff having large hands is nothing new, but I was googling around and found this “scientific article” from 2006:

I didn’t realize thst there might have been a medical condition involved, nor did I realize that his hands were bigger than most basketball players!
No wonder those chords are so hard to get your hands around!
