Stefan Meyer-Cullen in his office at work


   Chess engine is the unique software which is built into the program shell (e.g. "Fritz", "Arena", "Shredder") thus multiplying the force of the game shell. For example, "Kasparov Chess" is very good and clever shell. The maximum rating which can be set in it is 2600. And the rating of the chess engines reaches 3000-3200. That is why the chess engines are so popular. Where do the chess engines originate from and who makes them? This question is not trivial, vice versa it is quite actual, so it is worth talking about.

   The first record of the chess engine was made about 20 years ago. That was just the time when the UCI standard was developed – the universal chess interface, allowing the chess engine to be connected to the graphic interface of the program shell. The engine made to this standard can be easily connected to any chess program. The standard was worked out by Stephan Meyer-Kahlen, German programmer, who was born in 1968 in Düsseldorf. He is also the founder of one of the most famous chess programs – Shredder, which is the 12-times world champion among chess machines. The UCI standard was presented to the world by Rudolf Huber. The standard has great advantages. For example, if the engine does not save the database of the games played (although it is better if this task is performed by the engine), then one can easily manage this database by UCI. As the UCI protocol is absolutely free, it gives it the advantage over the other protocols. It can be used for private purposes and as the open-source as well. This protocol was used by only a few programs until Chessbase Company (producing Fritz) began to support this protocol in 2002. Nowadays, this protocol is used by about 100 chess programs.

   The majority of the chess engines are made very thoroughly and published in the net absolutely free of charge. In Russia there are the developers making engines, as well. E.g. SmarThink developed by Sergey Markov, GreKo developed by Vladimir Medvedev, Strelka developed by Yuri Osipov. These engines, as well as many others, can be downloaded from our website. As the number of the chess engines is growing, we chose the best ones, as there is simply no possibility to present all of them here.
