ShashChess 180822: Tal, Petrosian & Capablanca Rumble

The last post showed that Shash is not stronger than most of Stockfish clones including the original. I was curious how the famous world champions strength are translated by making a separate compile for each character and then mix each one. 

The results are interesting: Petrosian ranks higher than Tal and Capablanca. Overall, the combination of Tal + Petrosian scored the highest, beating the default Shash character by 1.25% ELO.

This is not the ultimate ranking for Shash but just a snapshot of how its characters strength manifest in a small tournament. It needs to have more rounds to have a definite conclusion. But even so, I can be sure that Capablanca's style is the weakest with a huge difference in ELO rating of 46.15% from the second last placer. 

Tournament conditions:
Tournament manager: cutechess-cli 1.0
Time control: 60/60+1

Time margin: 1 second
Option.Threads: 1 
Opening: 100 positions
Rounds: 200, repeat each position for black and white

Stockfish 18081801 vs. Clones


The last Stockfish vs. Clones tournament was primarily an experiment using the cutechess tournament manager. I was intrigued that cutechess could handle 16 concurrent matches very easily without noticeable degradation of the responsiveness with the computer which is an old AMD Athlon with 4 cores and 16GB RAM. It was ran under the latest PCLinuxOS without a single time forfeit. The previous tournament manager I used was Arena 3.5.1 which could handle about 7 concurrent games and beyond that the computer become sluggish resulting numerous time forfeits. I doubled the concurrency to 32 and still it ran without sluggishness and time forfeits. Perhaps it could run 64 concurrencies...

The other significant change was the use of cross-compiler under Ubuntu 18.04 with mingw version 7.3. This was the system used by abrok.eu to compile Stockfish which was faster than the one I made under Windows/mingw. I discovered that it could accept the -flto option which does not run under Windows. The resulting benchmark is faster using the cross-compiler and made CFish overtake Stockfish in the ranking. Official CFish does not come with an executable so I made one from the Ubuntu cross-compiler. The other clones were using their own executables which were probably optimized by their respective authors.

There were two new entrants in the tournament, namely CorChess and ShashChess. The other change was the use of the later versions of Stockfish, Brainfish and Raubfisch.

The higher concurrency of 32 made me double the number of rounds from 100 to 200 for greater statistical accuracy. The 10 man round-robin tournament with 200 games each was finished in approximately 16 hours using only 1 computer. This amazed me for it will take a very long time to finish with the Arena GUI.

This is the tournament condition:
Time control: 60 moves in 60 seconds base + 1 second increment
Time margin: 1 second
Option.Threads: 1
Resign score: 200 cp
Draw score: 20 cp after 40 moves
Concurrency: 32
Book: 100 variations, 2 moves deep, alternating

Stockfish 180729 vs. Clones


After some time of relative quiet, I decided to make a tournament for the purpose of knowing the current relative strength of Stockfish against its many clones.

I choose the better known SF clones which are in step with the latest version of Stockfish. To my surprise, Stockfish came in second behind the assembler based AsmFish and stood higher than the other SF clones which are supposedly made to surpass the original. But I suspect that the reason why Stockfish 180729 is stronger than most is because it was made by Abrok which I found to have strong compiles lately.

The tournament was a round robin with 100 games against each other.
Here are the  tournament settings:
Tournament manager: cutechess linux version
Book: custom book of 50 variations with 2 moves depth derived from the most common opening of different book sources.
Time control: 60 moves in 60 seconds base + 1 second increment, repeating
Win rule: 200 cp
Draw rule: 15 cp after 40 moves
Computer used: AMD Athlon, 4 cores, 16GB ram
Option.Threads: 1
Concurrency: 16
