Morlock is a hobbyist chess engine in Go.
Author - Henning Rohde
It supports a few standard techniques and protocols and is currently mainly used to re-implement the following historical chess engines:
TUROCHAMP (1948) by Alan Turing and David Champernowne
Turochamp is an implementation of Turing's original "paper" chess engine. Turochamp uses a full search with an unbounded quiescence search of "considerable moves" using material ratio and position play heuristics:
* [turochamp-1ply](https://lichess.org/@/turochamp-1ply). Rating ~1300 (blitz/rapid).
* [turochamp-2ply](https://lichess.org/@/turochamp-2ply). Rating ~1400 (blitz/rapid).
BERNSTEIN (1957) by Alex Bernstein, Michael de V. Roberts, Timothy Arbuckle and Martin Belsky
Bernstein is a re-implementation of the first complete chess engine: Bernstein's chess program on the IBM 704. Bernstein uses a selective search limited to 7 "plausible moves" for computational feasibility:
* [bernstein-2ply](https://lichess.org/@/bernstein-2ply). Rating ~1200 (blitz/rapid).
* [bernstein-4ply](https://lichess.org/@/bernstein-4ply). Rating ~1400 (blitz/rapid).
SARGON (1978) by Dan and Kathe Spracklen
Sargon is a re-implementation of Spracklens' early commercial chess engine. Sargon uses a full search with material exchange, king/queen pins and board control heuristics:
* [sargon-1ply](https://lichess.org/@/sargon-1ply). Rating ~1300 (blitz/rapid).
* [sargon-2ply](https://lichess.org/@/sargon-2ply). Rating ~1400 (blitz/rapid).
* [sargon-3ply](https://lichess.org/@/sargon-3ply). Rating ~1500 (blitz/rapid).
* [sargon-4ply](https://lichess.org/@/sargon-4ply). Rating ~1600 (blitz/rapid).
Each engine can be played 24/7 for free on [lichess.org](https://lichess.org). They have quirks, blind spots and limitations, which is part of their charm -- and play at low search depths to entertain rather than win.
