Call flag

[beco]

Hi dear all,

What is the command the engine must print out to "call flag" when the opponent is out of time?

Thank you,
Beco.

Hi Beco,
You shouldn't print anything!
Under winboard/xboard it is not the engine that detects if the opponent is out of time. It's the GUI. The same goes for UCI.

Hi dear Peter,
Thank you for your prompt answer. I was really expecting a command like "flag" (in the matter of fact, I tried it! ). But now this bad news... Maybe we can suggest it to Tim Mann?

Best wishes,

Beco.

Hi Beco and welcome here.
I prefer the GUI takes control of flags because that makes engine's simpler. Note that you would need to know exactly when the opponent sent its move to winboard/arena in order to be sure about a time forfeit. Every GUI has some (small, but real) delay, so it's better IMO to let the GUI control that.
