Houdini Help
It is important to define a fixed set of games that should be played in a test,
rather than to use a random set of games, where there is a danger of selective
reporting. A Nunn match is only valid if exactly twenty games are submitted. It is
entirely reproducible and transparent to everyone. This is even more true if the precise
hardware configuration is known, and the thinking times and evaluation of each move
recorded, which the program does automatically.

3.8.12 Engine tournaments (with humans)
Engine

T ourna m e nt

This program can stage entire tournaments with many participants, fully automatic.
This is the best way to rank chess engines. It is in some ways better than engine
matches, since some programs may have problems with one rival while doing much
better against others. In engine tournaments, each program meets a variety of
opponents, and the overall playing strength is determined.
Setting up a match can be done quickly and easily. You invite engines to a
tournament, set a time control, specify the number of rounds, start the tournament
and leave the computer to do everything else by itself.
When you click "Engine "T ourna m e nt " you are asked for a file name (ending with: .
cbtourn). After that, a dialog box appears in which you can set up the tournament (or
continue an existing one).
Title: Enter a name for the tournament. This will appear in the tournament column
of the games list.
