A chess engine is usually a back end with a command-line interface with no graphics or windowing. Engines are usually used with a front end, a windowed graphical user interface such as Chessbase or WinBoard that the user can interact with via a keyboard, mouse or touchscreen. This allows the user to play against multiple engines without learning a new user interface for each, and allows different engines to play against each other.

The meaning of the term "chess engine" has evolved over time. In 1986, Linda and Tony Scherzer entered their program Bebe into the 4th World Computer Chess Championship, running it on "Chess Engine," their brand name for the chess computer hardware[2] made, and marketed by their company Sys-10, Inc.[3] By 1990 the developers of Deep Blue, Feng-hsiung Hsu and Murray Campbell, were writing of giving their program a 'searching engine,' apparently referring to the software rather than the hardware.[4] In December 1991, Computer-schach & Spiele referred to Chessbase's recently released Fritz as a 'Schach-motor,' the German translation for 'chess engine.[5] By early 1993, Marty Hirsch was drawing a distinction between commercial chess programs such as Chessmaster 3000 or Battle Chess on the one hand, and 'chess engines' such as ChessGenius or his own MChess Pro on the other. In his characterization, commercial chess programs were low in price, had fancy graphics, but did not place high on the SSDF (Swedish Chess Computer Association) rating lists while engines were more expensive, and did have high ratings.[6]

In 1994, Shay Bushinsky was working on an early version of his Junior program. He wanted to focus on the chess playing part rather than the graphics, and so asked Tim Mann how he could get Junior to communicate with Winboard. Tim's answer formed the basis for what became known as the Chess Engine Communication Protocol or Winboard engines, originally a subset of the GNU Chess command line interface.[7]

Also in 1994, Stephen J. Edwards released the Portable Game Notation (PGN) specification. It mentions PGN reading programs not needing to have a "full chess engine." It also mentions three "graphical user interfaces" (GUI): XBoard, pgnRead and Slappy the database.[8]

From 1998, the German company Millenium 2000 briefly moved from dedicated chess computers into the software market, developing the Millennium Chess System (MCS) protocol for a series of CD's containing ChessGenius or Shredder, but after 2001 ceased releasing new software.[10] A more longstanding engine protocol has been used by the Dutch company, Lokasoft,[11] which eventually took over the marketing of Ed Schröder's Rebel.

Chess engines increase in playing strength continually. This is partly due to the increase in processing power that enables calculations to be made to ever greater depths in a given time. In addition, programming techniques have improved, enabling the engines to be more selective in the lines that they analyze and to acquire a better positional understanding. A chess engine often uses a vast previously computed opening "book" to increase its playing strength for the first several moves, up to possibly 20 moves or more in deeply analyzed lines.[citation needed]

Some chess engines maintain a database of chess positions, along with previously computed evaluations and best moves, in effect, a kind of "dictionary" of recurring chess positions. Since these positions are pre-computed, the engine merely plays one of the indicated moves in the database, thereby saving computing time, resulting in stronger, faster play.

Some chess engines use endgame tablebases to increase their playing strength during the endgame. An endgame tablebase includes all possible endgame positions with a small amount of material. Each position is conclusively determined as a win, loss, or draw for the player whose turn it is to move, and the number of moves to the end with best play by both sides. The tablebase identifies for every position the move which will win the fastest against an optimal defense, or the move that will lose the slowest against an optimal offense. Such tablebases are available for all chess endgames with seven pieces or fewer (trivial endgame positions are excluded, such as six white pieces versus a lone black king).[12][13]

When the maneuvering in an ending to achieve an irreversible improvement takes more moves than the horizon of calculation of a chess engine, an engine is not guaranteed to find the best move without the use of an endgame tablebase, and in many cases can fall foul of the fifty-move rule as a result. Many engines use permanent brain (continuing to calculate during the opponent's turn) as a method to increase their strength.

Distributed computing is also used to improve the software code of chess engines. In 2013, the developers of the Stockfish chess playing program started using distributed computing to make improvements in the software code.[14][15][16] As of June 2017[update], a total of more than 745 years of CPU time has been used to play more than 485 million chess games, with the results being used to make small and incremental improvements to the chess-playing software.[17] In 2019, Ethereal author Andrew Grant started the distributed computing testing framework OpenBench, based upon Stockfish's testing framework,[18][19] and it is now the most widely-used testing framework for chess engines.[citation needed]

The results of computer tournaments give one view of the relative strengths of chess engines. However, tournaments do not play a statistically significant number of games for accurate strength determination. In fact, the number of games that need to be played between fairly evenly matched engines, in order to achieve significance, runs into the thousands and is, therefore, impractical within the framework of a tournament.[22] Most tournaments also allow any types of hardware, so only engine/hardware combinations are being compared.

The ratings on the rating lists, although calculated by using the Elo system (or similar rating methods), have no direct relation to FIDE Elo ratings or to other chess federation ratings of human players. Except for some man versus machine games which the SSDF had organized many years ago (when engines were far from today's strength), there is no calibration between any of these rating lists and player pools. Hence, the results which matter are the ranks and the differences between the ratings, and not the absolute values. 2ff7e9595c
