Games


The Tournament

The host was represented by two programs, Cheiron and Alpha I, a single processor version of Zugzwang. Reigning World Microcomputer Champion Hiarcs wasn't represented by Mark Uniacke, but a local operator, who unfortunately lost some time between moves up and then [5] [6] [7] . MChess on the other hand was operated by an encouraged Peter Schreiner with great care. Richard Lang was abort on behalf of Chess Genius, Johan de Koning with The King. From the United States Bruce Moreland was present, while Junior was operated by local university staff. Fritz, who just won the Shannon Trophy a few months before did not participate in person, but his twin brother Quest by Frans Morsch.

Titles

After a lot of tough and thrilling matches, the title of the Professional Microcomputer Chess Champion was finally shared between MChess Pro 5.0 by Marty Hirsch and Chess Genius by Richard Lang, which were tied with 8 out of 11 each. The title of the "absolute" Microcomputer Chess Champion was decided by a playoff, which was won by MChess. Ferret by Bruce Moreland from the United States played a strong tournament and became third a half point behind the top scorers, and gained the World Amateur Microcomputer Chess Champion title, since the tied Nimzo 3 by Chrilly Donninger et al., from Austria, had to withdrawal the playoff for logistical reasons, after already being late due to the nerve-racking Blitz playoff. World Blitz Computer Chess Champion was won by The King by Johan de Koning from The Netherlands in 9 playoff matches against Nimzo 3.

System Tal vs XXXX

A small anecdote appeared in the last round between Chess System Tal by Chris Whittington versus Martin Zentner's XXXX (FourX). Instead of a queen-promotion with a fast mate, the graphical System Tal board indicated a minor promotion to a knight! System Tal operator Thorsten Czub played the move over the board and had to resign on behalf of Chess System Tal, while Chris, already celebrating the safe point in the cafeteria, was not amused when he arrived back on the board. A bug in a graphics drawing routine indexed the wrong piece and caused some rule discussions in the news groups [8] [9] [10] . Chris on place argued the PVs, as stored inside a log-file, indicated the mate score and the correct moves. Nevertheless, Tournament Director Jaap van den Herik was unpersuadable.

Winner's Curse

With hindsight MChess' title of the "absolute" Microcomputer Chess Champion wasn't the expected commercial breakthrough of the MS-DOS program. Windows 95 was already dominating the PC-market, and the trials by his European Distributor Martin Stamer to place a DOS program in the mass market was not that successful. Due to some formal advertisement faults by Stamer and some questionable and euphoric statements in his Chess Computer Catalogue 1996 [12], problems arose, with monetary consequences for the programmers under contract, Marty Hirsch [13] and Gerd Isenberg. Mutual preliminary injunction initiated by Stamer's business rival Ossi Weiner and continuous court cases over years [14] was the consequence. In February 1997 Marty made a public accusation against his former distributor in a newsgroup [15], while he was already about to collaborate with Weiner. The German Magazine Computerschach und Spiele broached that issue [16], where Stamer made a counterstatement.
