Blue Marlin and Swordfish 14.4

At the beginning I would like to point out that Swordfish and Blue Marlin are not stronger than Stockfish. If you are looking for more Elo you may not be interested. The purpose of these engines is to provide interesting and effective chess games. Swordfish and Blue Marlin are engines based on Stockfish and ideas used in Bluefish by Eelco de Groot.

Swordfish has a reasonable balance between strength and tactical abilities. It still has solid style of playing and achieves good results in test suites. It can be useful for analyzing sharp positions where regular Stockfish can overlook some tactics.

Blue Marlin is more focused on king attack and sacrifices. It provides very sharp and attractive games.

Yes, indeed... Would be an interesting match Koivisto 7.2 by Ipman vs BlueMarlin... Swordfish is more mature and solid interesting match would be vs SF14 or Dragon.

Both engines are strong with interesting playing style. But they have many up and down in their positional evaluations due to their tactical style. If an average chess player wants to practice with these engines ,player shouldn’t care about these engines evaluations so much and should continue opening moves according to chess base opening data and with self confidence. Don’t worry about the evaluation numbers that they show because this number changes in positions very soon. Or a player can use blue marlin only for checking tactical blunders.

On my tests, Blue Merlin 14.4a is STRONGER than Stockfish 14.1, and is more aggressive and has a pleasant style. Please continue to update it!

Alex, I just read on TalkChess that you are saying that Blue Marlin 14.4a is GPLv3 non-compliant? How? Maybe I am overlooking something?

The source and authors file is present in my upload. Not sure about Triton6654's link, though. Never checked.

You can go directly to the mediafile link the author posted at OpenChess for a separate download of the source:

Don't let the trolls at TalkChess discourage your contributions there.smile  I frequently follow your threads.

Sorry, I have already corrected the post and added the download links. I'm very happy for the GPL v3 compliance, because so it will be compiled also for Linux, Android and macOS and help other authots to fine tuning their SF derivatives. Also Swordfish 14.4 is very strong and i'm just adding it in my topic.

So I have to say Blue Marlin 14.4 is a really strong engine
but Blue Marlin14.4a seems a little weaker to me
I have now played a few games and tournaments with Blue Marlin 14.4 on InfinityChess and have done well with the engine, but with engine 14.4a I was always a little worse
