README

My first bitboard-based engine.

How to Use

Obtain a third-party UCI-compatible chess GUI. Build this module's binary file locally (go build). In the GUI settings, set the binary file as the "engine to use."

Perft Milestones

Perft is a debugging function that compares a move tree's leaf node count against an accepted value. The largest performance gains were from reducing memory allocations and the associated GC time.

Depth	Time	Speed (million leaves/s)
perft(4)	0.15s	1.35
perft(5)	1.4s	3.5
perft(6)	16s	7.1

Want to build your own engine?

I recommend starting by making a command-line game that makes random, legal moves against the player. At that point, reading about move generator debugging, search algorithms, and evaluation algorithms will help your engine make stronger moves.
