Yeah, wait until the fastest compile get out !
Sure (It should also not hurt against stronger than Stockfish 8 because there was no regression measured against master (playing wthout contempt), but keep in mind it is also used in analysis, unless you explicitly set it to zero (and Chessbase remembers the settings, which in the past could be a problem with Chessbase GUIs. I don't know how that is now.) CFish I'm sure has a different solution by now from Ronald (I have not checked) But the patches for Stockfish have not yet been decided on.Nordlandia wrote:Is default contempt of 20 correct if facing SF8
SF 9 vs SF 8
Cfish has the same solution as Houdini (as far as I understand Houdini's solution).Eelco de Groot wrote:CFish I'm sure has a different solution by now from Ronald (I have not checked)
In my experience, Houdini with "Analysis Contempt" box enabled doesn't default to white's point of view, it only does that if white has the advantage. If black has the advantage, then it'll shift to black's point of view. Whatever side has the advantage will have it inflated, and will have Houdini trying to play drawish from the side with the disadvantage.syzygy wrote:In analysis mode, contempt is forced to zero unless the user has checked the "Analysis Contempt" option. If that option has been checked, contempt will be from white's point of view (so set it to a negative value to give black positive contempt).
A practical disadvantage of this solution is that the user has to set "Analysis Contempt" to negative if he/she wants to analyze with positive contempt from black's point of view.syzygy wrote:Cfish has the same solution as Houdini (as far as I understand Houdini's solution).Eelco de Groot wrote:CFish I'm sure has a different solution by now from Ronald (I have not checked)

In gameplay mode, contempt is for the side to move. "Analysis Contempt" is ignored.
Komodo has a similar but slightly different solution. Instead of "Analysis Contempt", it has "White Contempt". If my understanding is correct, the only difference is that White Contempt also forces contempt to be from white's point of view in gameplay mode.
