Thoresen Chess Engines Competition (TCEC).North American Computer Chess Championship.International Paderborn Computer Chess Championship.Internet Computer Chess Tournament (CCT).Titles gained in these tournaments garner much prestige for the winning programs, and are thus used for marketing purposes. To some extent, this is a self-fulfilling prophecy if an amateur engine wins a tournament or otherwise performs well (for example, Zappa in 2005), then it is quickly commercialized. Historically, commercial programs have been the strongest engines. Most tournaments also allow any types of hardware, so only engine/hardware combinations are being compared. 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.

However, tournaments do not play a statistically significant number of games for accurate strength determination. The results of computer tournaments give one view of the relative strengths of chess engines. Many engines use permanent brain as a method to increase their strength. 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. Such tablebases are available for all positions containing three to six pieces (counting the kings) and for some seven-piece combinations.

Endgame tablebases in all cases identify the absolute best move in all positions included (identifying the move that wins fastest against perfect defense, or the move that loses slowest against optimal opposition). 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. An endgame tablebase is a database of all possible endgame positions with small groups of material. Some chess engines use endgame tablebases to increase their playing strength during the endgame. Since these positions are pre-computed, the engine merely plays one of the indicated moves in the database, thereby saving compute time, resulting in stronger more rapid play. 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. According to one survey, the top engines have been increasing in strength by an average of 67 Elo per year since 1986.ДЄ 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. 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. This is partly due to the increase in processing power that enables calculations to be made to ever greater depths in a given time. Increasing strengthД¬hess engines increase in playing strength each year. Some interfaces support both protocols, while others, such as WinBoard, support only one and depend on subsidiary interpreters to translate. The Winboard Protocol is more popular but many chess engine developers feel that the Universal Chess Interface is easier to implement. Some engines support both major protocols, and each protocol has its supporters. There is another protocol, the Universal Chess Interface. The WinBoard Protocol was itself upgraded and the two versions of the protocols are referred to as: 'WinBoard Protocol 1' (original version) and 'WinBoard Protocol 2' (newer version).

When XBoard was ported to the Windows operating system as WinBoard, this protocol was popularly renamed to 'WinBoard Protocol'. The command-line interface of GNU Chess became the initial de facto standard, called the Chess Engine Communication Protocol and was first supported by XBoard.

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. Most chess engines do not have their own graphical user interface (GUI) but are rather console applications that communicate with a GUI such as XBoard, WinBoard or glChess via a standard protocol. The chess engine decides what moves to make, but typically does not interact directly with the user. In computer chess, a chess engine is a computer program that analyses chess positions and makes decisions on the best chess moves. Home :: Chess :: Computer chess Chess engine
