I saw this post on HN around 3 months ago (https://news.ycombinator.com/item?id=31964685) and it fascinated me.
3 months later and I have a fairly decent AI (~ beats the 2200 bot on chess.com) and would like to share it. It's been my favourite project and honestly chess programming is super fulfilling and a huge time sink. hope ya'll enjoy
