My adventure with chess engine development started a good few years ago, and one of the issues I’ve definitely struggled with a lot was: how to test if a new build with a very sound feature is actually performing better than the old one. This article is a summary of the experience I gained after four engines, where each of them had a different methodology.

A small patch for the Inanis, addressing bugs found by the TalkChess community. The most important one fixes random crashes caused by the move legality check, giving false indications in rare cases. In the result, illegal moves were processed which led to the board state irreversibly corrupted.

The first version of Inanis, a brand new chess engine written in Rust, is finally out! I’ve tried to make it as much feature-complete as possible, so it’s fully usable with any GUI supporting UCI protocol. If you find any bug, please make an issue with possibly the most detailed description and steps to reproduce the problem, so I can investigate it.
