Thanks for this interesting tournament.

Contempt is default for everyone?

Hi,

Komodo contempt is 0.
All others contempt is default.

In this and YLCET tournament Komodo is now beating Houdini. But TCEC is different so far with older 2012.00 version.

Clemens Keck: Mark Lefler said in tcec chat that PB=enabled on dual xeon system is not necessarily worse off than PB=off. What is your impression with ponder enabled so far?

ponder off is very entertaining :)
You can see and compare the engines calculation.
15 cores is really enough for a good performance, and ponder on tournaments are seldom.
Komodo does well so far, seems to be improved.

From Houdini manual:

The objectively highest level of play is achieved without contempt, i.e. Contempt value 0.

A contempt value of 2 will typically reduce the draw rate in a match by about 4%.

So for tournament matches against K and SF, C=0 is better choise against default.

H with C=0 might perform better in same ongoing match i suppose.
