Is it possible?

[Bill Rogers]

I have Arena, Winboard and ChessGUI. Is is possible to set up a trournment in which the the sides are uneven. By that I mean different time conrols or depth of search for each side?

In ChessGUI and Winboard_F you can use time odds (1, 1/2, 1/3, ... 1/n).
In ChessGUI you set it per engine.
Though fully functional, the feature is currently switched off.
If you have already used recent/current ChessGUI, I can switch on the feature for you.

ChessGUI 0.112 shall have it switched on.

Best,
Matthias.

Hi Matthais
Well I thought I had ChessGUI but a quick look at my PC and I could not find it. It might have been on my other one which has crashed, but...
If you could I would like the newer version, that is the one you quoted.
Thanks
Bill

With PSWBTM + WinBoard_F you can run time-odds tourneys.

Install the engine in PSWBTM with the extra engine option:

Code: Select all

WBopt /%sTimeOdds=N

to reduce its time with a factor N.

Similarly, if you want to limit the depth of a certain engine, install it with the extra engine option

Code: Select all

WBopt /%sInitString="new\nrandom\nsd=D\n"

where D is the depth you want to limit the engine to.

When the engines are started, WinBoard_F will intercept such engine options (everything after the "WBopt"), and uses it as an option for itself. (overruling whatever was in the winboard.ini file or on the command line). It thereby replces any %s in the option by "first" or "second", depending on which place the engine got assigned.

You will have to use the latest WinBoard version for this, that can be downloaded from the link http://home.hccnet.nl/h.g.muller/alpha.tst (which you would have to save as / rename to winboard.exe). This version even has an option /timeOddsMode=0 (or 1) that will control what happens when two engines that are both handicapped play against each other. (i.e. if they both get reduced time, or if the time is renormalized so that the slowest one always gets nominal time.) This option you can put in the winboard.ini.

Download and install ChessGUI.
Send a mail to "mgemuh at yahoo.com" with "ChessGUI" in header because I don't have your email adress.

The ChessGUI.exe I will send you is not suitable for people who have used ChessGUI in the past, but have skipped recent/current version.

Best,
Matthias.

Hi,
in Arena you can set up for each engine individually a percent of the strength. Not a perfect method, but it may be useful. It is in the Engines menu, then manage, then special.
Hope it helps,
Yves
