Thinking time: 24'+5'' per game/engine (average game-duration: 60', so around 25 games per day are played). Average thinking time in the middlegame is around 45'' per move. Stockfish 8 calculates around 6.5 meganodes per second in early middlegame (with 8 threads). So the played games are high-quality-chess.

Current participants: Stockfish 8, Komodo 10.2, Houdini 5. Contempt set to +15 (means: Contempt=1 for Houdini 5 (!!!)) for all engines.
I decided, to play only with the "big three" and take Shredder 13 out - Shredder is too weak.
