We have a new leader in my tests. Although the difference has not been finally so big as it was after the first 480 games, this is the best SF I have tested ever. As a reference it is:
- 2 ELO points stronger than Stockfish 221214 MZ (my second best)
- 11 ELO points stronger than Stock-Fish SF6
- 14 ELO points stronger than SF 020115 Development
- 39 ELO points stronger than Stockfish 5
- 58 ELO points stronger than Komodo 8
- 75 ELO points stronger than Houdini 4 and
- 118 ELO points stronger than Gull 3 XP.
