Hi!

I haven't been very active with this engine lately, the last version 15.3a was released about 10 months ago, but I've spent a lot of time testing recently and I'm happy with the results. I notice that Swordfish 15.4 can play really strong but a bit different than Stockfish. That was the main goal.

Hi Dorsz
I am very happy that you care so much about your
Engines (specially swordfish) test results before releasing. This swordfish also plays very well. Its fantastic for all purposes. I like it. Many thanks and best wishes.

Tests were longer than it was planned because after long break with Swordfish I had to verify lots of unclear patches, and at the end I had two Swordfish candidates that played extremely strong. The one I released and the other one based on quite old net nn-1337b1adec5b.nnue with a bit different settings for it. I had to verify deeply which was better.
