Leela Chess Zero (abbreviated as LCZero, lc0) is a free, open-source chess engine and volunteer computing project based on Google's AlphaZero engine. It was spearheaded by Gary Linscott , a developer for the Stockfish chess engine , and adapted from the Leela Zero Go engine.
On desktop, it is the default chess engine bundled with the Internet Chess Club interface programs BlitzIn and Dasher. On mobile, it has been bundled with the Stockfish app, SmallFish and Droidfish. Other Stockfish-compatible graphical user interfaces (GUIs) include Fritz, Arena, Stockfish for Mac, and PyChess.
A chess engine generates moves, but is accessed via a command-line interface with no graphics. A dedicated chess computer has been purpose built solely to play chess. A graphical user interface (GUI) allows one to import and load an engine, and play against it. A chess database allows one to import, edit, and analyze a large archive of past games.
Hardware requirements for chess engines are minimal, but performance will vary with processor speed, and memory, needed to hold large transposition tables. Most modern chess engines, such as Stockfish, rely on efficiently updatable neural networks, tailored to be run exclusively on CPUs, [9] [10] but Lc0 uses networks reliant on GPU performance.

Scid is a powerful Chess Toolkit with many features. It can interface with XBoard engines (such as Crafty and GNU Chess), and UCI engines (e.g. Fruit, Rybka and Stockfish). Using Scid, one may play games against human opponents (on the Free Internet Chess Server), or computer opponents.
The uci_limitstrength parameter tells engines with this feature to play at a lower level. The uci_elo parameter specifies the Elo rating at which the engine will aim to play. Engines that have implemented uci_elo include Delfi , Fritz , Hiarcs , Houdini , Junior , Rybka , Shredder , Sjeng and Stockfish .
