Senpai 1.0 x64 vs. The Big Three GrandMonsters

After the Senpai 1.0 x64 matches posted 2 days ago where it showed a big 200 ELO rating increase from the "junior" Fruit 2.1 version, I decided to conduct a follow-up gauntlet matches against the the Big 3 GrandMonsters to find out how Senpai would perform and also to see if it will break the rank order sequence of the strongest chess engines.

The computer used was an AMD quad core with 4GB of physical memory and Windows 7 operating system. It was a monolith 100 round gauntlet matches where only one instance of the tournament was created to minimize distortion of the results.

The results showed that Senpai scored 31.5 points out of 300 games or just 10.5% average against Stockfish, Houdini and Komodo. Senpai won 5, drawn 53 and lost 242 games in the very lopsided matches. It also was not able to break the ranking order of the Big Three.

Given the development pattern of the Fruit chess engine, it may take another 10 years for Fabien Letouzey to make the Senpai  chess engine catch up the strength of Stockfish, Houdini or Komodo!

Here is the performance of Senpai:
