[shrapnel]

Hi Neel
Why did you again change Cowardice setting ?

[Dr.Wael Deeb]

Hi Neel
Why did you again change Cowardice setting ?

The question is:

Why not__

Agressiveness.=110
Cowardice=100

[neelbasant]

Hi Neel
Why did you again change Cowardice setting ?

Anil

When i analyzed with Cowardice=85 it sometime did analyze sometime too aggressively which missed some critical moves.
So i changed it to 105 .

May be some people find this weird but i really like SF while analyzing.

Neel

[leavenfish]

Would these settings be equally good for long or infinite analysis? How about a fixed depth of 29 ply for analyzing a series of middle game positions? Just curious since I was thinking about having it or Komodo 6 analyzing the end points for my chess repertoire that usually extends to 25-35 ply.

[leavenfish]

Anyone?

[neelbasant]

Did you analyze with this setting ?

It finds earlier than default setting .

Main purpose of this setting is to find other equally good moves which other engine including SF default may not find.

[leavenfish]

I have just used the default SF DD settings so far.

I am running some 'deep analysis' via Chessbase. I do like that it goes so deep so quick. I am not sure about its evaluation functions that deep however.

Basically, my question still remains as to what people who have tried different engines under infinite analysis...or even 'Deep Analysis', what they think the best current engine might be.

[ouachita]

what they think the best current engine might be.

the answer to this question has been debated and is being debated more heatedly than the ACA. The best answer today seems to be, it depends largely on the match/tournament results you review, and/or who you ask and where their allegiances lie.
