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

   Jun-03-17 I Nikolic vs G Arsovic, 1989
 
MarkThornton: At the 1992 British Chess Championships, in Plymouth, my Rd 8 game lasted for 14.25 hours and 165 moves: I won early in the 6th session. The game reached the endgame of KQ+RP v KQ on move 65, and finished precisely 100 moves later. At the time, someone researched whether it ...
 
   May-30-17 Korchnoi vs Yudasin, 1994
 
MarkThornton: After 51...Rxa6, Korchnoi looks to be in trouble, but the Great Defender survived against the odds yet again...
 
   May-30-17 S Atalik vs G Mohr, 2001
 
MarkThornton: THe last P capture of the game is on move 87
 
   May-30-17 K Spraggett vs P Dias, 2001
 
MarkThornton: BLack's last P is captured on move 47
 
   May-30-17 G Schories vs Leonhardt, 1905
 
MarkThornton: BLack's last P is captured by 46.Kxe4
 
   Nov-08-16 L Dominguez vs A Giri, 2011
 
MarkThornton: My best guess is that White's phone went off before he played his 5th move.
 
   Feb-12-16 Euwe vs Alekhine, 1935
 
MarkThornton: This was game 22: Euwe had just won 2 games in a row, including his first win with Black, to level the score at 10.5-10.5
 
   Feb-05-16 G Friedemann vs Keres, 1940
 
MarkThornton: After 28.N moves, Black has 28...Nb5 or 28...Nd5 attacking both Qc7 and Re1. Hence. White tries 28.Qxc6, as the lesser of two evils, but resignation would have been more polite.
 
   Feb-05-16 J Yrjola vs E Hintikka, 2006
 
MarkThornton: An interesting game, which fizzled out into a draw when all the major pieces were exchanged.
 
   Jul-31-15 Menchik vs G A Thomas, 1930
 
MarkThornton: I may be wrong, but I think the first time control was often at move 30 in that period.
