Backgammon

I have achieved my childhood dream* of writing a backgammon AI that can beat me**, and it runs in a web browser ;-)

You can try your luck here https://grwhitehead.github.io/jsmcts/backgammon.html

* jk, but kind of true... after getting the Z-80 assembly language source code to SARGON, a computer chess program, I became obsessed with writing a backgammon AI on my TRS-80 Model 3

** beating me at backgammon is a low bar

I still have the SARGON book!

This is from the days before the internet, when we all typed programs in from magazines. Imagine publishing the source code for a program in a printed book these days... or writing a game AI in assembly language.
