Hi Fx7_fx5,

A common problem among polyglot users is that some think that they can use the same polyglot.ini and just change few things here and there, I am not saying this is your case but I wanted to mentioned it.

My recommendations are:

-For the polyglot section, one needs to read the documentation and see what are the options available for that particular version. A good example is SyncStop, this option is not available in older versions. I don't know about Fonzy's fork, but unfortunately with Michel's fork is that the manpage.txt found at http://alpha.uhasselt.be/Research/Algebra/Toga/polyglot-release/ is alaways updated for the latest polyglot version but old versions of manpage.txt are not saved, for this reason I recommend to always use latest polyglot version.

-For the engine section:
Both polyglot and the UCI engines are smart enough to ignore options not implemented by them, the problem is when we are not declaring very important options, example: FireBird has a PawnHash option, the documentation says that PawnHash should be around one quarter of Hash, so if you are using 256MB of Hash, then PawnHash should be 64 MB, but if is not declared, then the engine uses the default which is 32 MB. If documentation is available, one should read it andget familiar with the options.If not documentation is available, what we can do is double click on the engine executable file, when the dos prompt opens, enter the command uci and all options will be displayed.

-----------------------------------------------

Once we know all the options we have for polyglot and the engine sections, we can create a better ini file, and I recomend renamed it to something related to the engine, for example: firebird1_MP_64.ini

Telling you what to put in each option is beyond my intentions in this post. Depends on the computer, depends if you are playing in pogo or yahoo, etc.

There are few things I can say:

For 1/0 games use 128 MB hash, no less than 64 and no more than 256, trail an error will tell you what is the best setting for you.

For 4/2 I will use 256MB or 512 MB. I don't know if this is true or no but sometime ago someone told me that Hash should be set to a value that come from the power of 2 (64,128,256,512,1024) not 96,384, etc.

MultiPV=1 HOW BOUT THIS?

This should be always be 1 when playing. It can be set to 2 or more when in analyzing mode.

I think I am going to try to create a new program similar to Polyglot_GUI, but this new program will prompt for the polyglot exe file one is intending on using...wish me luck. Note: This is accomplish flawlessly by the combination of the latest WinBoard and Polyglot but I haven't have the chance to understand it well, maybe darklord can give us a lesson on this.

cheers,

cheers,

Thank you for the explanation Matematico myself had many doubts about the polyglot, you know how much I use ChessBase in my games because of this difficulty we'll see if I get on well with the poly.

PS: I was away pogo occur because some family problems I am having trouble connecting an update to be made friends already thank you

Good luck in the new project
