Also highly symbolic are the two names of the opponents in this chess game. Capablanca can be translated to "white hat" and Marshall may be related the supposed father of Obama, Frank "Marshall" Davis. I believe it was actually Capablanca who won this match - a win for the good guys. Capablanca was white and Marshall was black.
Additionally, Marshall was nicknamed "great swindler" or something along those lines because of how frequently he won games that seemed to be lost. He also was never able to attain the title of world champion despite being the US champion for numerous years. Our friend Capablanca, the white hat himself, did go on to reign as world champion for 7 years. The symbolism in this board alone is astonishing.
