Zappa, Zap!Chess or Zappa Mexico, is a UCIchess engine written by Anthony Cozzie, a graduate student at the University of Illinois at Urbana-Champaign. The program emphasizes sound search and a good use of multiple processors. Earlier versions of Zappa are free (though not open-source software) and the current version (Zappa Mexico) is available at Shredder Computer Chess.^[1]

History

Zappa scored an upset victory at the World Computer Chess Championship in August, 2005, in Reykjavík, Iceland where it won with a score of 101⁄2 out of 11,^[2][3][4] and beat both Junior and Shredder, programs that had won the championship many times.^[5][6] In the speed chess portion of the tournament Zappa placed second, after Shredder.^[7] Zappa's other tournament successes include winning CCT7 on the Internet Chess Club^[8] (ICC) and defeating GrandmasterJaan Ehlvest 3-1.^[9]

In Mexico in September 2007 Zappa won a match against Rybka by a score of 51⁄2 - 41⁄2.^[10] Many commentators had predicted a slew of draws based on the strength of the engines, but the differences in style provided an interesting match with several decisive games and many fighting draws. For some time, Zappa was considered one of the two strongest commercially available chess programs; see engine rating lists like CCRL^[11] for current rankings. Some speculate that Zappa's more efficient SMP parallel search could make it stronger on enough processors.

Trainz 2019 dlc: jr rolling stock pack ( trs19 ). In March 2008 Anthony Cozzie announced that 'the Zappa project is 100% finished', which includes both tournaments and future releases.^[12]

In June 2010, Zach Wegner announced that he had acquired the rights to maintain and improve the Zappa engine. The improved engine competed in the 2010 WCCC under the name Rondo, achieving second place behind Rybka before the latter's disqualification.^[13][14][15]

Commercialization

Immediately after the successful WCCC 2005, there were plans to commercialize Zappa, but the first attempts with Vincent Diepeveen failed.^[16] In April 2006,^[17] a commercial version dubbed Zap!Chess running under the Fritz GUI was released by ChessBase.^[18]

The version of Zappa that won the Zappa-Rybka match, Zappa Mexico, is sold by Shredder Computer Chess,^[1] is compatible with Windows and Linux computers with up to 512 CPU cores and supports multipv analysis and Nalimov tablebases.

Notable games

• Zappa vs Crafty, WCCC 2005, 1-0 Despite Zappa being a relative newcomer, it managed to win the tournament and in general caused a bit of a stir in the computer chess community.^[3]

Introduction

Zappa is a chess engine, or a program that plays chess. It issimilar to Deep Blue - only much better - and is best known for itsgood parallel speedup. It has competed in many computer chesstournaments with its best result coming at the World Computer ChessChampionship in 2005, where it took first place with the score of 10.5/ 11. Like Fritz or Shredder, it is a standard chess engine, which intechnical terms means it is a brute force alpha-beta searcher with aheuristical evaluation. You can buy a copyhere.

Retirement

The Zappa project is 100% finished. This includes both tournamentsand future releases.

Genealogy

Zappa is not named for the great Frank Zappa, or at least not directly. I got the name from Austin Powers 2, which has a scene where Dr. Evil talks about how he has divided his moon base into 'Moon Unit Alpha' and 'Moon Unit Zappa', a pun on Frank's quixotically named daughter Moon Unit. I have never listened to his music, although I like many of his quotes. Interestingly, Frank liked chess and used to play with the band quite a bit.

Features

Zappa Mexico Ii Chess Engineer

Zappa Mexico can be used on Windows or Linux computers with up to 512 CPUcores. Unfortunately, the parallel implementation relies on sharedmemory, so you cannot hook two computers together with an ethernetcable and use them together, unless you are willing to give SGIseveral hundred thousand dollars. Zappa Mexico also supports multipvanalysis, Nalimov tablebases, and as a UCI engine it can be used inmost of the standard chess GUIs. To the best of my knowledge, not asingle computer has caught fire while running Zappa.

Great Moves

Zappa Mexico is commercial. You can buy a copy here. However, you candownload an older version for free. It is a command line programwithout a graphical chessboard, so if the idea of typing commands byhand does not appeal to you, you will need to download a GUI. Arena is free; the commercialChessbase (Fritz), Shredder, and ChessPartner GUIs should also work.For all you old-schoolers, Zappa does support WB2 and will work inXBoard or WinBoard. If you want to run engine-engine matches, youwill also need to supply an opening book.
