Comparison Houdini - IvanHoe - Stockfish

[Stefan]

The time management of some engines is not optimal especially at super fast games. So I use 1s fixed time per move for my test. Now time management is no longer an issue. The new IvanHoe 53 does not run on my AMD-CPU. Therefore I chose the version 54 that is a bit stonger than version 63 and equal to 57a. I decided to use no endgame tables. One reason is that I don't know how to load the Triple Bases automatically on engine start.

Houdini is a monster on 1 CPU. In another thread when I said it was at least 5% faster than IvanHoe, that was kind of well...the truth is 10% or more.
