Crystal,
a UCI chess engine by Joseph Ellis derived from Stockfish, first published in August 2019 1. Crystal focuses on better problem solving abilities, and includes fortress detection code. It further addresses some rarely occurring positional or tactical blindness due to too aggressive reductions and pruning. Crystal 3.0, released in September 2020, is able to use NNUE evaluaton 2.
