Greetings.

I have just released the first version of my UCI Engine 'Yakka', written in Delphi Object Pascal.

https://github.com/CJDalrymple/Yakka/releases/tag/v1.0

I estimate it to be around 2850 ELO +/-30 CCRL Blitz 2+1 (Yakka v1.0 x64 using 4CPU).

I have only tested it on my desktop with Intel Core i9-9900K CPU @ 3.60GHz, Windows 11 x64, using 'Arena' GUI.

Please let me know of any bugs, compilation-problems or stability issues.
Any ideas, comments or suggestions for improvement always welcome.

Looking forward to seeing how it fares against other engines.

A lot of enjoyment over the past months, and more to come.

Regards to all.

Hello,

v2.2 of Tcheran was released today with a couple of bug fixes for issues which caused the en passant target to be forgotten during search. This was pointed out during the 107th Amateur competition being run at the moment, which pushed me to release early.

There's some other refactoring included in the release, but nothing that gains strength. Elo gains are almost entirely a result of the bug fixes and are:

Code: Select all

Elo   | 23.11 +- 9.18
Conf  | 8.0+0.08s Threads=1 Hash=16MB
Games | N: 4096 W: 1655 L: 1383 D: 1058

Code: Select all

Elo   | 24.81 +- 17.94
Conf  | 60.0+0.60s Threads=1 Hash=128MB
Games | N: 1024 W: 397 L: 324 D: 303

Obsidian 12 released

From the GitHub-site:
Obsidian 12.0 vs Obsidian 11.0 (STC)
Elo | 56.70 +- 5.42 (95%)
Conf | 10.0+0.10s Threads=1 Hash=16MB
Games | N: 8006 W: 2672 L: 1377 D: 3957
Penta | [9, 525, 1767, 1566, 136]

This new release is about on par with Berserk 12 (slightly stronger or slightly weaker depending on the time control).
The goal for the next release is to take down Dragon 3.3
