  Black Vampire: <True Blue:That's a shame, the puzzle should have started at move 12!> No, it isnīt. Itīs a Monday puzzle, so it must be easy (if you want to start at move 12, the puzzle would be for Wednesday or Thursday); besides, Black made a mistake, because 12...Qxe4+ is much better, according to Crafty 19.01. In fact, the checkmate is only possible after the pretty greedy 14.Qxh8??

  Black Vampire: Well, True Blue, 11.Qb5+ was the first important mistake, but the real blunders were the captures of both of the Black rooks and the pawn b7.
Feb-19-07  Themofro: Easy puzzle to start off the week, main difficulty is to do away with Bb4+ which would also win i beleive, but the queen sac is much more elegant.
Feb-19-07  tjshann: I got to this late today, but did manage to solve it after realizing fairly quickly that discovered check did not lead to a clear Monday one-two and out.
Feb-19-07  kulitbulilit: Who is NN!!? Why wasn't his name given in full? Will somebody tell me please! I'm intrigued!
Feb-19-07  LPeristy: Took me a rediculously long time, as I was fixated on trying to get something out of the disco check. But I did get it eventually.
Feb-20-07  Tactic101: This double rook sacrifice and Queen sac definately was much safer than Anderssen's Immortal Game.
Jan-18-09  WhiteRook48: NN takes too many sacrifices...
Nov-28-11  IRONCASTLEVINAY: NN means anonymous.

  Infohunter: <kulitbulilit: Who is NN!!? Why wasn't his name given in full? Will somebody tell me please! I'm intrigued!>

<IRONCASTLEVINAY: NN means anonymous.>

Correct; the abbreviation is derived from the Latin "Nomen nescio," which means, "I do not know the name."

May-14-12  Llawdogg: Both rooks and then the queen!
May-15-12  LoveThatJoker: Cool game by Diemer, today's Player of the Day!

  al wazir: How could Diemer have played a correspondence game with someone whose name he didn't know?

Before the Internet existed you had to send moves *by mail*. For this it is necessary to have a mailing address. How could Diemer have obtained the address of his opponent without learning the name too?

I am sure you will all join me in congratulating him on his excellent decision.

It's a mystery. I made exactly the same point at Zukertort vs Chess Club, 1868.

Jul-11-18  paavoh: Who would want to give his/her name and be immortalized after such a disaster?

Perhaps Black/the magazine editor was polite enough to remove the name before publishing the game score.

Jul-11-18  morfishine: 'NN' is better known for his remarkable longevity having lost games in 7 centuries

I played a guy once in the Chicago Open who "offered" his rooks, but I only took the first one & retreated back and eventually won easily. He asked me after why I didn't take both of them (and referenced he studied, Take My Rooks), so I told him, "Why be greedy? I've already got a material advantage." All that study wasted on the assumption both rooks would be taken.
