MOCHI

MOCHI - the MinOr CHess engIne

MOCHI is a toy project to implement a simple chess engine in Go.

MOCHI is an UCI chess engine. That means you need a GUI to play against it. Currently only HIARCS (https://www.hiarcs.com/) is tested. I plan to test a few chess GUIs, eventually.

See my blog posts for more information:

• A chess engine in Go: part 1 - the idea

• A chess engine in Go: part 2 - board state and FEN input

• A chess engine in Go: part 3 - move generator and PERFT results

• A chess engine in Go: part 4 - move generator fixes & logo

• A chess engine in Go: part 5 - MOCHI plays chess!

Perft-Testing

MOCHI has built-in perft testing. To execute a test, run

# defaults to go run mochi perft cpw 4, see below
go run mochi

# run PERFT of the chess programming wiki test positions to the given depth (4)
go run mochi perft cpw 4

# run PERFT of the given FEN position to the given depth (5)
go run mochi perft fen "rnbqkbnr/pppppppp/8/8/8/N7/PPPPPPPP/R1BQKBNR b KQkq - 1 1"  5

Extensive test results are saved in perft-results.
