Many thanks for the DOTS8 ! Here it is in use.

To re-phase my last: the only thing about ACT & TTT was some of the Mate in .., a low number of moves might be a little easy for newer engines.

Soon I will try Swordfish & Blue Marlin

Great! Testsuites do not get the attention they deserve, and it must take human skill to make them.

For example in my post virtually all the Lc0 nets are in the expected order - except it was a surprise that my expensive 3080 benefited from the smaller faster LgDist, only maybe a minor disagreement ...

Thank you for your testsuites! I had a lot of fun combining them:

Thanks for the mention, sarona !

DOTS4 is my favorite book.

Also, I noticed a few "matches between engines" using DOTS4 on Lc0's Discord.

(I am fine, just doing other things. I think I will post this forum again in 2 weeks to 1 month.)

The tactical advantage of Stockfish over Lc0 is very big.

Don't you test Blue Marlin anymore?


Sorry, I've been too busy, but I would like to get back to your Swordfish/Blue Marlin - very interesting ideas!

I've used DOTS3 on Lc0's discord a few times with a link to their posts here. I am ...

Here is another from my last post here.

Game #9, Sf 1-0 Lc0, 42 moves (rev. #10 Lc0 1/2-1/2 Sf)
White had already sacrificed a rook for bishop and pawn, then with 23.Rxb7! it gave up its other rook for black's other bishop, then 23...Rxb7 24.g3! and white's B-pair outplayed black's R-pair.
