Blue Marlin - strong Stockfish derivative focused on king attack and sacrifices. It provides very sharp and attractive games.

According to my tests Blue Marlin 15.2a has the same strength as Blue Marlin 15.1, but tactics is improved.

Fortunately, more games showed that I was wrong.

hi dorsz,
I have updated the Blue Marlin 15.2a with SFNNv5 and with default latest net.
But the problem is there is lots of errors while compiling. Can you please compile this and post an new version here.
same net update can be used for swordfish also.

Hi!
Please do not publish my engine with your settings. I don't like it.
Blue Marlin 15.2a uses old architecture on purpose, because it has more sacrificial tendencies. I tested it in hundreds of positions. You did not change the settings for new architecture, you just simply put new net in it, you used some patches and values that do not help Blue Marlin play as it is made for. Comment about Swordfish has no sense, because it was released before BM15.2a but it has new net and new architecture.
If you want stronger engine just download the latest Stockfish from abrok.

I messed a bit here. I compared wrong files. Maybe you changed the architecture well, but other parameters are modified without a good reason. I don't know why you get errors. Anyway I don't recommend new architecture for BM15.2a. It is like modyfing an engine like Crystal to make it stronger but forgetting why the changes were made in it and the highest Elo was not the purpose.

if highest Elo was not the purpose then how will you win? fluke ? why play a game when winning is not the priority.

How will I win what?
Do you think all engines' authors should give up their work just because Stockfish is stronger?

No I didnot mean that and you need to understand why i try to update the clones published its because with stockfish updates if i could achieve a stronger clone which is stronger than original stockfish itself it will be a achievement for me. So for your info i have updated Blue Marlin,swordfish, stockfishMZ, Kayra 1.4, ProteusSF and I do a test using testset OTSv4 and it contains 400 positions with which I test and decide whichever clone solves better and use that derivative to play in engine room. For now your previous BM 15.2 is the best derivative and play with that in engine room. I think you dont know where you stand when comparing updated clones.

There is no modification in Blue Marlin that improves Stockfish strength. If we start to revert the changes and accept all from new Stockfish, Blue Marlin will lose its style, it will became Stockfish again.
