Hi Jim,
thanks for Zangdar.
I can install the engine as UCI with Shredder 12 GUI.
But if I start Zangdar, Shredder-12 GUI crashed (BMI2 version, same for AVX2-ZEN version).
No reaction and I have to restart the GUI.
Best

Re: New J.A Compiles
Of course, I saw it and downloaded it with joy, now I test it almost around the clock. Excellent engine, excellent compilations from you. Last night, for example, it crushed Dragon 3.3 from the initial positions of the TCEC-25 final with a score of 33-13 in a match of 104 games, time control 1+1. I know that translating Obsidian to old instructions is a huge challenge, primarily neural networks, and the author himself directly said in one of the interviews that he cannot do it. But you can! I always knew that you are the best, for more than a decade. I made this request, because Obsidian is the fastest growing of the top engines, and each number in the name is a real increase in the game's strength, noticeable in tests. But, also understanding how difficult this work is even for you, I cannot ask for this too often. I repeat, you are transferring the engine to old instructions, which even the author himself CANNOT do. Not doesn't want to, but CANNOT.Jim Ablett wrote: ↑Wed Apr 30, 2025 6:15 pmI compiled 15.14 which is only a few weeks ago (a couple of commits behind latest)SlonoSlonar wrote: ↑Wed Apr 30, 2025 4:36 am Dear Maestro Jim, could you compile the new Obsidian: https://github.com/gab8192/Obsidian

We have the avx2.gif, but not the avx2.exe! Maybe it's a misprint?
Thanks again!
