Match title: This is the title that will appear in the tournament column of the
games list.
Define: These two buttons allow you to select and configure the engines. You
can set the hash table size, the use of endgame tablebases, the openings book and
possibly the engine parameters. You can give an Elo rating for the engine. The left
engine has white in the first game.
Blitz/long/fixed: You can stage engine blitz matches, or play the games at
tournament time controls. It is also interesting to set a fixed depth which can be set
to different values for each engine.

Number of games: You can specify how many games should be played.
Move limit: This limits the length of individual games. The number gives the
number of ply (half-moves) after leaving the openings book. In the database, the
games are stored without a result, but with an evaluation symbol.
Tip: If you want to check an openings book, set the move limit to “1”. The program
will go to the ends of different lines, calculate one move and save them with an
evaluation symbol.
Permanent brain: You can specify whether the engines should continue working
while the opponent is thinking. This, however, means that each engine will be using
50% of the processing power.
Openings DB: This is a special feature which allows you to select a database of
games. The engines load each game, jump to the end and play on from there. This
function allows you to stage “theme tournaments” and also conduct interesting
experiments, like the “Nunn match”, in which each side must play ten representative
openings positions with black and with white. These positions are included on your
program CD (Nunn.cbf) and were selected by Grandmaster John Nunn. They have
become the standard for testing chess engines without the influence of the openings
book.
