Crystal Chess Engine




Let me introduce Crystal, a super chess engine – in my opinion – that replaced Cfish in terms of analysis performances. Today I was testing it with my main pc (Intel i7-4771) with this position against the latest Stockfish beta… This last one solved the position after 15 minutes of analysis, at depth of almost 50 plies, while Crystal solved it as soon as I clicked the Infinite Analysis button!

  Stockfish

  Crystal!


Although it did not performed well in the blitz tournament I setup lately, this engine is a must for any chess player intending to analyse or solve problems. Try it yourself!

I have decided to include this specific version (5 KWK) and not the latest one because it was much faster to solve the problem above. In facts I have never seen such a powerful engine in all these years.



WHAT IS CRYSTAL?


Crystal is chess engine created and mantained by Joseph Ellis derived from Stockfish. It is focused on better problem solving abilities and includes fortress detection code. Crystal is able to use NNUE networks.
