December 4, 2018 Chess Engines Collection 1.3 released

Chess Engines Collection version 1.3 has been released.

It features two updates: Stockfish 10 (the newest version of the strongest engine in the world at the time of this writing), and its assembler variant armFish.

As part of our testing we have organized an interesting match between Stockfish 10 and armFish 20181204. This match was played on a powerful octa-core phone.

This means that each engine had 3 cores, since our core allocation algorithm ensures fairness (an equal number of cores for each engine) while keeping one core free for the Android system and other background apps.

The match consisted of 4 blitz games with 5 minutes for each side and no increment. A coin flip decided that Stockfish 10 started the first game as white.

While this means nothing per se (especially since we were taking screenshots at random moments, thus depriving the side to move from some useful CPU cycles), Stockfish 10 won this match (2½-1½), the results being as follows:

  • Game 1: Stockfish 0 - 1 armFish (White forfeits on time)
  • Game 2: armFish ½ - ½ Stockfish (drawn by repetition)
  • Game 3: Stockfish 1 - 0 armFish (Black forfeits on time)
  • Game 4: armFish 0 - 1 Stockfish (White forfeits on time)
