The latest CCRL update (13th April 2024)

[Ray]

Yes, as I said, different tester, different hardware, different book, different GUI and even a different compile of Stockfish 15.1. But the large error margins are surely the dominant factor. +/- 20 Elo or so on each engine with the low number of games.

Stockfish 15.1 on one thread was tested:
Intel i9 10900
bmi2 compile
Pohl SuperGM 4Moves book
Cutechess GUI

I've found a bug in Aprils Rating List: https://ccrl.chessdom.com/ccrl/4040/gam ... 47].pgn.7z
EloValues for three engines seem to be missing:
KnightX 3.7b 64-bit - , e.g. in Round:874.2.29
Zangdar 2.15.03 64-bit - e.g. in Round:875.1.883
Renegade 0.10.0 64-bit - e.g. in Round:875.1.932

I haven't checked any other files yet, and don't know whether this bug is already known, but hope I can help with this reporting.

[Ray]

Possibly because there are not enough games for a reliable rating.

You mean games played in April, not the April ratings list ?

[Peter]

Yes, it's in the PGN-Files of the games (the one I linked above), not in the rating list.

Hello, author of Austerlitz here.
On 4 December I shared Austerlitz version 1.4.7 and asked for testing it, but I still haven't got any return information about it.
Actually, I hoped to see it appeared on the next ranking list. Could I know how Austerlitz testing is going and when could I possibly expect to get estimated elo of the engine? I noticed given ccrl links don't work, at least on my device.

Nobody knows it, could you link Ginko to Fritz ?

Nobody knows it, could you link Ginko to Fritz ?

I'm pretty sure that most are aware, but it's in the engine notes anyway.

I am sorry, everybody knows official Fritz, not Ginko , so everybody is searching now Frtiz 19 especially if there is Fritz 18 in CCRL.
