I mainly compose chess problems these days. Please visit http://pdb.dieschwalbe.de/search.js... to see a selection of my compositions.

This problem first appeared in The Problemist Supplement, July 2009.

Mark Thornton (after Tibor Orban). Dedicated to Etienne Dupuis, author of Euclide, a program for solving and composing proof games.

Position after Black's 4th move. How did the game go?

Solution to Orban's Problem: 1. e4 e6 2. Bb5 Ke7! 3. Bxd7 c6 4. Be8 Kxe8

Solution to my problem: 1. Nh3 d5 2. Nf4 Bg4 3. Nxd5 Bxe2 4. Nxe7 Bb5! 5. Bxb5+ Kxe7 6. Be8 Kxe8 7. O-O

White's 7th move rules out the following possibilities: 1. Nh3 d5 2. Nf4 Bg4 3. Nxd5 Bxe2 4. Nxe7 <Bxf1> 5. Kxf1/Rxf1 Kxe7/Bxe7/Nxe7 6. Ke1/Rh1 Ke8/Bf8/Ng8

MarkThornton: I have discovered that Erwin l'Ami has annotated this game on his personal website: http://www.erwinlami.nl/partijen_hu... . Unfortunately, the annotations are in Dutch, which will be a barrier for some people.

MarkThornton: I have fed this game into Stockfish! and it immediately found a big improvement for White: <18.Kg1!> f2+ 19.Kg2 Rh2+ 20. Kxh2 f1=Q and now <21.Nd2!>. In order to defend the position, White needs to keep moves like Qh8, Qg8, Qf8 in reserve, and so must refrain from ...

   Dec-09-13 Zukertort vs Chess Club, 1868 (replies)
 
MarkThornton: Zukertort later rose to be one of the top 2 players in the World, but he was probably still developing his strength in 1868. Even so, the Unknown Chess Club put up impressive resistance and made Johannes work for his victory.
 
   Dec-07-13 A Galliamova vs C Lutz, 1997 (replies)
 
MarkThornton: 24....Rxe3 just screams to be played....but finding an accurate follow-up is very challenging (at least, it was for me!) Good play by Lutz, and also by Galliamova, who fought hard in a lost position.
 
   Dec-02-13 Reti vs Bogoljubov, 1924 (replies)
 
MarkThornton: The finest game in the career of one of my all-time favourite players. This game is without fireworks until the very end, but the build-up play flows so beautifully that it leaves a lasting impression. Bogoljubow also played well..... 15....e5 would have led to a draw, if his ...
