Polaris is a UCI chess engine, a full rewrite of its predecessor (my first attempt at a chess engine, also named Polaris).
Rating CEDR=2890
v.1.8.1:
Release republished due to outdated tag (again) (I am stupid)
This release fixes some strange behaviour regarding how tablebase scores are reported, and adds some additional safeguards to win/loss score handling in aspiration windows. Additionally, compilation should no longer spit out warnings from Fathom.
No strength difference exists from 1.8.0 :)
