Blue Marlin - Stockfish derivative that provides sharp and attractive games.

Blue Marlin 15.3 still uses the old architecture as the net used in it is great for sacrifices and attacks. Any new net is not willing to make such sacrifices at low depths (however they are stronger). The engine is suitable for playing and analyzing, it has reduced search explosion problems, it supports Polyglot books now.

Thanks Dorsz
I just played the new version 15.3 against the version 14.4 that I really like, two games are draw. Although version 14.4 is very old, but I like its style play, it solves Purzzles very well

If you want to run interesting matches between chess engines, and they do not have to be only Stockfish derivatives, you may want to take a look at my opening test suite available here: https://www.open-chess.org/viewtopic.php?f=7&t=3365
