Horowitz 2.1.0 released.

Horowitz is a UCI-compatible open source chess engine initially written in Go. Now rewritten in C++.

Logo from Darius (I couldn't find the Horowitz engine logo anywhere).

Here is what author OliveriQ wrote about the latest version:

"

This version essentially consists of a simpler evaluation function and a much faster search function. This has produced a reasonable gain in playing strength. Evaluation now uses PSQT's + Material (both now incrementally updated) and mop-up evaluation for converting late endgame positions. Other changes include various bug fixes.

Here are the final scores of v2.1.0 vs v2.0.0 in a match consisting of 100 games (TC 40/10s + 0.1):
