Who is N.N?

NN lose every games...couldn't even master a draw. Poor fella. Lately he/she has lost to club players....I guessed being more experiencd doesn't mean improvement
I don't understand how NN could play all the greats like kasparov, capa, etc.. Some games are from simul, blindfold or even odds. But some are just normal games.
Maybe one day I will meet NN and get a chance to play with him/her. I will let him/her win for a change. It will be the first ever win by NN !!
But if you lose to NN, you will become NN.
