Simply put - because the current ICGA 2019 situation is worse than the ICGA (2011) Rybka situation.

In August 2019 we (Chris and me) tested 150 engines on similarity and the results were astonishing regarding the top engines, especially Shredder 13, a similarity of 65% with Stockfish 7.

In September 2019 we posted the Similarity 2019 Report on Talkchess which immediately was moved by the current moderators (3 staunch ICGA supporters) to the (hidden) floor drain --> Engine Origins.

4 other observations we noted:

1. We tested the Rybka / Fruit similarity --> 68%

2. From Chiron 1.1 we got the following numbers:

Engine Chiron 1.1 and Robbolito show a similarity of 65.79%
Engine Chiron 1.1 and Houdini 1 show a similarity of 65.78%
Engine Chiron 1.1 and Ippolit show a similarity of 65.23%
Engine Chiron 1.1 and Strelka 5 show a similarity of 64.95%
Engine Chiron 1.1 and Bouquet 1.5 show a similarity of 64.42%


Chiron 0.87 was CCRL listed 2583, Chiron 1.1 2966, a 400+ elo jump.

3.
Shredder 12 CCRL : 2955 - No similarity in sight.
Shredder 13 CCRL : 3270 - Massive elo jump of 325 points, similarity with Stockfish 7 of 65%

4. Shredder and Chrion both participated the last 3 years (2016-2019) in the yearly ICGA WCCC.

Conclusion, like Rybka Shredder and Chiron should be investigated by the same standards as Rybka in 2011.

EQUAL JUSTICE or UNDO the 2011 verdict.
