Tournament with long thinking-time

 

Playing conditions:

 

Hardware: i7-6700HQ (2.6 GHz) Notebook (Quadcore), Windows 10 64bit, 12GB RAM

Fritzmark: 4 cores / 7 threads: 18.4 / 8825 (CPU-speed reduced to 99% (to switch off the Intel Turbo Boost))

Hash: 4 GB per engine

GUI: Fritz 13 GUI (no draw, no resign)

Tablebases: None for the engines, 3-5 Nalimov for GUI

Openings: My SALC_V5_10moves book. Download it here

Ponder, Large Memory Pages: Off

Thinking time: 20'+5'' per game/engine (average game-duration: 52', so around 30 games per day are played). Average thinking time in the middlegame is around 40'' per move. Houdini calculates around 7.5 meganodes per second in early midgame (all engines running with 7 hyperthreading-threads, when thinking). So the played games are high-quality-chess.
