Tournaments and significant games.

Programs, machines and results

WCCC means World Computer Chess Championship; WMCCC means World Microcomputer Chess Championship. Tournament programs and experimental hardware are distinct from retail products and from the physical specimens in this collection. A shared title is identified as such.

Results below are taken from the ICGA tournament database, a retrospective compilation of journals, event records and participant communications. Event dates are not mistaken for the publication dates of that database. The source register records this distinction.

Travemünde 1981 · WMCCC

Fidelity X won six games and lost to Philidor X in the displayed main table. The separately recorded three-game playoff against Chess Champion Mark V was a clean sweep. The database separates these records; its main table is not a complete account of the commercial division. SciSys X is not treated as the retail Mark V.

Budapest 1983 · WMCCC

Elite Auto Sensory won the championship. Prestige Challenger was a separate entrant and finished fifth. A Prestige with a later Budapest program is not thereby the physical tournament winner; identifying the collection’s EPROM versions requires specimen evidence. The champion beat Mephisto X but drew against Novag X and Super Constellation. Prestige lost to Chess 2001 and Novag X.

Glasgow 1984 · WMCCC

Four programs shared the title. Fidelity Elite X beat Psion, yet lost to Princhess X. Its four wins, two draws and one loss do not support a claim of an undefeated championship. The hardware values describe tournament entrants, not all retail machines bearing Glasgow-related names. The L’Empereur result supplies competition context without proving that a photographed collection specimen was that entrant.

Lyon 1990 · WMCCC

Mephisto came close to a perfect tournament, beating Gideon and conceding its only half-point to Échec 1.9. This documents dominance within this event; it does not supply a universal Elo rating or prove the strength of every retail Lyon module.

Vancouver 1991 · WMCCC

Gideon won the event, although Mephisto X defeated it in the final round. Mephisto X in turn lost to MChess and The King. A retail model named Vancouver cannot be described as the overall winner from this table. The database’s playoff column is not explained sufficiently here to assign a separate manufacturers’ title. Gideon is credited to Ed Schröder; this is program history, not proof of the collection R30’s tournament participation.

Madrid 1992 · WCCC

Ed Schröder’s Chessmachine won the World Computer Chess Championship. It drew with RISC 2500 and defeated Kasparov Sparc in the last round. Chessmachine did not play runner-up Zugzwang in this table. This WCCC is distinct from the microcomputer WMCCC series; it is not a title automatically held by a retail TASC R30, its The King firmware, or every Gideon version.

Reading dates, strength and weakness

The Lyon and Vancouver PGNs retrieved use 1 January dates which have not been independently confirmed; only the year is presented here.

A tournament score measures performance against that event’s opponents under its conditions. It does not establish a universal Elo or a playing-style diagnosis. These games were selected to show decisive wins, losses suffered by champions and draws against eventual winners. Positional evaluations and claims such as “brilliant” or “tactically weak” await annotated analysis with reproducible evidence.
