Stockfish for MorphOS
=====================

Stockfish is one of the strongest chess engines in the world. It analyses
chess positions and computes the best moves, using a neural network (NNUE)
to evaluate the positions. The network is built into the program, which
explains its size.

Stockfish has no board of its own: it is a UCI engine, used by a chess
program that draws the board and sends it the moves. It can also be used
directly in a Shell.

This version is about 2.5 times faster than the previous MorphOS release.


HOW TO RUN IT
-------------
In your chess program, choose Stockfish-19 as the UCI engine.

In a Shell, start Stockfish-19 and type for example:
uci
position startpos moves e2e4
go depth 15
quit

"Stockfish-19 bench" measures the speed of your computer.


ENDGAME TABLEBASES
------------------
Stockfish can use the Syzygy tablebases to play endgames perfectly. Two
small tables are in the Syzygy drawer. More can be downloaded from
https://syzygy-tables.info (the 3, 4 and 5 piece tables are about 1 GB;
6 pieces need 150 GB).

setoption name SyzygyPath value PROGDIR:Syzygy

Several drawers are separated by ";", for example Work:wdl;Work:dtz.
