Here's a very attractive mate from the match NN vs. Adolf Anderssen, 1872. NN is commonly thought to stand for "no name", but it's really an abbreviation of the Latin
nomen nescio, literally "I do not know the name". NN in chess matches stands for an anonymous player, possibly an amateur. In the internet age, NN is frequently used to designate someone playing under a nickname.
From the position given below, it's Black to move and mate in four.
Don't cheat!
Solution:
1. ... Bg2+
2. Rxg2 Qf1+
3. Rg1 Ng3+
4. hxg3 Qh3#
There is a shorter mate if and only if the rook takes the knight at g3, thus:
1. ... Ng3+
2. Rxg3 Qf1+
3. Rf1 Bg2#
The FEN for the puzzle is:
7k/1p4p1/7p/3P1n2/4Q3/2P2P1b/PP3q1P/6RK
