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 White's 7th move. How did the game go?

It is based on this famous problem by Tibor Orban, Die Schwalbe, 1976 (Commended)

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: 34...Nd5 allows a nice finish, but 34...Nh7 is not much better: 35.Bc4+ Kh8 36.e6 and Black's game looks hopeless.

MarkThornton: I have just found this remarkable game, in which a World Champion defeated his immediate predecessor: Kramnik vs Anand, 2008 . It was played not long after this game - was Anand aware of Shulman vs The World?

MarkThornton: White is clearly winning in the final position, so the result given, a draw, is suspect.

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 ...
