Zappa Mexico Ii Chess Engine

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.

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 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

Unfortunately in computer chess games most of the beautifulcombinations occur in the notes. Chess engines are simply so strongtactically that they almost never fall into traps. Still, here are afew tricks from the good old days.

1rb2rk1/4R1p1/1pqn1pBp/3p4/5Q2/1NP3PP/6PK/4R3 w - - 0 30

From Zappa-Searcher, CCT6. Here Be8 wins the exchange, but R1e6!!wins overwhelmingly. The game continued 30. Re6 Bxe6 31. Nd4 Qc4 32.Qxd6 Bxh3 33. Kxh3 Kh8 35. Nf5 and it is obvious Zappa's attack is toostrong for Black to survive.

4r1k1/3R3p/p5p1/n3r1q1/8/P1Q5/1P6/KB1R4 w - - 0 43

From Zappa-Crafty, 2005 World Computer Chess Championship inReykjavik. Here Zappa played the elegant Re1! (Rxe1 Qg7, and Whitethreatens Qxa5 Rxa5 Rxe8) and the game continued 43... Qf6 44. Rxe5Qxe5 45. Ba2 Kh8 46. Rd8! 1-0. This is a relatively easy combinationfor a modern program, but it's still pretty.

Zappa Mexico Ii Chess Engineer

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.
