Weiss is a chess engine written using VICE as a base, and otherwise inspired by Ethereal, Stockfish and Demolito.
Weiss is part of the OpenBench testing framework. You can help us out by letting your idle CPUs run test games!
Weiss appears in the CCRL, CEGT, FastGM, and SRL rating lists.
A big thank you to everyone in TCEC chat for helping me out, as well as motivating me to give this a try to begin with!
Weiss supports the following:
-
The size of the hash table in MB.
-
The number of threads to use for searching.
-
Path to syzygy tablebase files.
-
Allow Weiss to query and play moves suggested by noobpwnftw's online opening database.
Note: Weiss will print a string indicating it supports Ponder, this is done to make cutechess GUI show pondermove accuracy. Weiss does not actually support this option.
