Re: What was the last good Stockfish?
Thank you very much Carl! And everyone who tried Bluefish, thanks for trying the Bluefish out! Had not expected anything like this for the work it was but it sure was a nice thing to see it, Bluefish even used on PlayChess. Too much praise for my efforts, as you know, if it works, it only works because of those thousands of hours computing time on Fishtest that balanced all the pieces of positional code in Stockfish with each other. That is what makes it possible. To play a little bit like Tal, you have to know exactly what is just crazy and what is a calculated risk.carldaman wrote: ↑Sun Sep 29, 2019 7:51 amWell, you must be congratulated on this one, Eelco! Bluefish has got a savage attacking style, just from the changes you made. A much better playing style and personality than all the top engines!Eelco de Groot wrote: ↑Fri Sep 27, 2019 4:59 amSure, I can make it available, CarlSee Bluefish BMI2 (Beta).
No guarantees it has "style" though. It's just a half hour work or so, not a real Stockfish variant or fork yet.
I've run some test matches, but with little time available. I hope to be able to post some of its games when I get more free time.
Cheers!
Debugging is twice as hard as writing the code in the first
place. Therefore, if you write the code as cleverly as possible, you
are, by definition, not smart enough to debug it.

If you thought the game vs Vitruvius - granted, not a top engine any longer, was spectacular, what would you say about the dismantling and destruction of one the top engines of today? Eman is one of the best SF derivatives out there, if not the strongest! We can watch it being blown away in amazing stylish fashion. This is chess from another world!
The hardware and nps were similar for both opponents in the engine room. Bluefish only used a fairly shallow book, 6 moves deep. I used a contempt setting of +33, since I feel that it makes it even stronger.
Before looking at the game, check out this position, as a preview of what transpired:
Eman is up two pawns and can capture either black Rook, but it hardly matters!
I don't know what others think (I suspect that less than 5% of talkchess readership is even aware of this thread), but I'm beginning to think that it could be worth trying to enter Bluefish into the next TCEC competition. It is a top engine right out of the box and may just be the most interesting chess playing entity out there at this moment, all the Leela clones notwithstanding!
Cheers and thanks again for the gift of Bluefish!
Re: What was the last good Stockfish?
If you are looking for engines that plays risky exciting chess check out Norman Schmidt's (aka Carotino ) version of Ivanhoe called Spaghetti Ivan and it is really strong and plays unusual lines as well.
Re: What was the last good Stockfish?
Thanks a lot, I'll check it out. I thought Carotino was Roberto Munter, though I may be wrong on that one. 
Re: What was the last good Stockfish?
So, did this happen and I missed it?

Re: What was the last good Stockfish?
You are right about Munter being Caritino.
Re: What was the last good Stockfish?
Another recommendation for exciting super aggressive chess is Cfish Tactical enabled , probably the best & my favorite for ruthless cutthroat chess.

Re: What was the last good Stockfish?
Well The Stockfish That has my attention for a while lately is Stockfish 160526bt (bullet/tactical) plays a pretty speculativeOvyron wrote: ↑Thu Sep 26, 2019 6:28 pmWhen I say "good", I'm talking about the playing style. The great thing about a playing style is that you don't need to play hundreds of games, a few are enough to showcase the style. Traditionally, I play 10 games with minimal books.
See here for context.
The contenders for being the last good versions of Stockfish are Stockfish 14051722, the very last one that allowed tweaking of settings, and Stockfish 5, with settings by Dayffd, that not only improve the style, but the strength of the engine
I never got to name these settings, let's name them... Lunatic...
My settings:
Stockfish 14051722 Lunatic
Pawn Structure (Midgame)=0
Aggressiveness=200
Cowardice=0
Dayffd's settings:
Stockfish 5 Fury
Mobility (Midgame)=180
Mobility (Endgame)=160
Passed Pawns (Endgame)=175
Aggressiveness=200
Emergency Move Time=20
I ran a match of 10 games after calibrating their strength so they played at the same level and could showcase their styles. (PGN for collectors)
You don't actually need 10 games, you can do it in 2. The reason 10 are needed is so that you get the 2 you need played in there
Because then, this happened:
Lunatic goes and plays the Blumenfeld Gambit by herself! But Fury doesn't care, she goes for the King and creates an attack Lunatic can't deal with!
But this seals it:
Wow! Did you see how Fury took Lunatic's King out in the open? Who cares if the attack didn't work in the end, this was some tasty style show off! That's why it's important to not let engines just go on depths they see the attack don't work and don't try to carry it over...
Stockfish 5 Fury might be the last good Stockfish, but if someone has an idea of another version that could play better than this I'm very interested
game....Also Stockfish Monte Carlo is unusual...my other favorite Stockfishes..(theres a ton)

Re: What was the last good Stockfish?
I have shared knowledge of several stockfish versions here I thought were unique attackers & defenders , but this one plays the most unusual lines I have ever seen " Stockfish Safe Attacks " , check it out !
