Will be interesting. I *think* the difference with 2.7 will be small. Not entirely sure.

Make sure to set the hash-size in your tournament software.
Or give dog the '-H 256' parameter for a 256 MB hashtable.
Because the default is now 16 MB and was 256 MB before.

Dog is a chess engine that complies with the UCI protocol. So the hash value (in matches and tournaments) is taken according to the general settings in the GUI. And Dog 2.8 respects the 256 MB setting.

Below is the situation from my LazySMP Test tournament after 3000 games. The 77th chess engine (Ghost 3.1 x64) was introduced because the CCRL blitz lists raise a big puzzle: the difference between Brutus 8.05 64-bit and Ghost 3.1 64-bit is 3 Elo points in the 2020-02-04 list and 128 Elo points (!!!) in the list from 2025-01-11. Some differences may exist, can be justified, but over 120 points.....??? Similarly,placing Wasabi 1.5.0 64-bit over Hedgehog 2.407 64-bit seems quite curious to me. Let's wait for more games in my tournament.

Introduced in my LazySMP Test Tournament Waldi 7 a good chess engine written in Java (the main author is Finn Eggers - Koivisto). Not many people know about this engine.

SoFCheck 0.9.1 beta 64-bit has 2383 Elo points (CCRL Blitz).



===================================================

Waldi 7 is a good Java chess engine.
There are some chess engines written in Java that I don't see either in Dušan Stamenković's big collection or in Günther Simon's RWBC XB/UCI Engines Chronology. Some over 2000 Elo points. Just an example-Lila 3.0.1 (UCI):
============================
https://github.com/stylextv/lila
============================

I know 84 free projects written in Java (+4 private: Chompster, Eowyn, FIBChess & Grok).

Waldi-Lila-Duch (all over 2000 Elo points) were never tested by CCRL (I don't even talk about CEGT anymore...). :wink:

I will also introduce Lila 3.0.1 in my LazySMP Test tournament (it will be the 82nd engine)!

Romanian League 2025
====================

:D

Six engines were not tested by CCRL. One was tested in an older version. Freyr is the oldest Romanian chess engine. He comes from Iași.

The situation after 53 games (TC=4'+2"):
