Bit Manipulation Instructions (BMI) is an interesting extension for the x86-64 architecture, introduced by Intel in Haswell processors (early 2010s). Its main purpose is, as the name suggests, increasing the speed of the most common bit operations by replacing manual calculation with dedicated instructions (which means hardware support). This article will focus on the performance of three example instructions: BLSI (reads the lowest bit), BLSR (resets the lowest bit) and TZCNT (counts the number of trailing non-set bits).

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.
