[what is this?]

The abbreviation "NN" is used to signify an unknown player, usually an amateur. Although NN is sometimes believed to stand for "no name", that is a misconception: it is in fact an abbreviation of the Latin nomen nescio which means 'I do not know the name.' uses "NN" to fill in spots in the database where a player's identity is completely unknown, and also for games on internet chess servers, where people often play anonymously.

Some of the first examples of NN's play were published by seminal chess authors such as Gioachino Greco and Pedro Damiano. In these cases, it is unclear if NN represents an actual adversary or if the games were composed for illustrative purposes.

Yes, no one can say NN is indecisive, and the market direction is clear!

Nice! I wonder if we could calculate NN's addition to wins over those worthies, he's got a couple of draws with <FSR>, so he can't be too bad.

Nah. That sounds like a load of hooey.

Jul-22-18  WorstPlayerEver: Greco beat NN 79-0

NN studied for 170 years, then they drew Phili. The same year they scored their first win!

There is much about chess that you have failed to take in over the years, a golden opportunity to learn chess has been lost. Maybe you should stop with the stupid videos and take in the chess information provided.

Feb-17-23  stone free or die: This is what a drip does...

Too dimwitted to see the obvious humor, and with nothing else to contribute, they take their own miscue as an invitation to spread vitriol and juvenile personal attacks.

Just more boring scat, the drip, drip, drip is continuous:

Feb-17-23  whiteshark: NN This slang acronym is most frequently used in online chatting and text messaging to represent the phrase <night, night.> It is used to say goodnight or end a conversation at the end of an evening.

That's it then!
