DESCRIPTION

12       This manual page documents the stockfish command.
13
14       stockfish is an UCI chess engine, to calculate chess moves
15
16       Stockfish  is  a free UCI chess engine derived from Glaurung 2.1. It is
17       not a complete chess program, but  requires  some  UCI  compatible  GUI
18       (like  XBoard  with  PolyGlot, eboard, Jose, Arena, in order to be used
19       comfortably.  Read the documentation for your GUI of choice for  infor‐
20       mation about how to use Stockfish with your GUI.
21
22       This  version  of  Stockfish  supports  up  to 8 CPUs, but has not been
23       tested thoroughly with more than 2.  The program tries  to  detect  the
24       number  of  CPUs  on your computer and set the number of search threads
25       accordingly, but please be aware that the detection is not always  cor‐
26       rect.   It  is  therefore  recommended  to  inspect  the  value  of the
27       "Threads" UCI parameter, and to make sure it equals the number  of  CPU
28       cores  on your computer. If you are using more than four threads, it is
29       recommended to raise the value of "Minimum Split Depth"  UCI  parameter
30       to 6.

36       books.  For information about how to create  such  books,  consult  the
37       PolyGlot documentation.
