Some days ago, I made a random match between Stockfish and Glaurung to satifsy curiosity on what is the relative strength of Stockfish in relation to its original parent. Glaurung chess engine was the creation of Tord Romstad which was last published in the year 2009 after Stockfish made its appearance. Marco Costalba forked the Glaurung 2.1 version in 2008, named it Stockfish and was eventually chosen to continue what Glaurung had begun.
The ELO rating of published Stockfish 131109 version is 3219 while Glaurung 2.2 is 2590 with a huge difference of 629 points. Glaurung's ELO strength is already worth a normal human chess Grandmaster's strength. It could probably make a reasonable fight with a GrandMonster like Stockfish.
I choosed the Stockfish 131111 build against the last Glaurung 2.2 in the grand match. As the 100 round match unfolds before my eyes, I watched the awesome strength of Stockfish ruthlessly destroying its father Glaurung. The final score was 98.5-1.5 in favor of Stockfish, where Glaurung never managed a single win but just lucky to salvage 3 draws.
Here is the crosstable:
Stockfish 131111 x64 vs. Glaurung 2.2 x64 - Match 100R 1M1S
|1||Stockfish 131111 x64||98.5/100||· ·· ··||97-0-3||147.75|
|2||Glaurung 2.2 x64||1.5/100||0-97-3||· ·· ··||147.75|
