Xboard protocol: Abort after move 1

[ohnesorg]

Hi,
I'm programming my own chess engine. Now it works fine, with winboard.
To play in the internet (freechess.org) I use the winboard zippy feature.
I have the following question:
In winboard GUI, you can choose to abort the game after the first move, so that it does got get rated.
But in the xboard protocol I did not yet find a way to allow my engine to send an abort message to abort a game, for example if the seek does not match its criteria.
Can anybody help here?

With 'tellics' the engine can send anything to the ICS. Also an abort command.

But I don't understand why you would want to. You placed the seek yourself. So how can it not match its criteria? What criteria are you thinking off anyway? The variant?

Normally you filter out challenges that do no match your criteria by the ICS formula. WinBoard would not even get them, let alone the engine. WinBoard would refuse to accept challenges in variants the engine does not support, or that ae not in the -zippyVariants option.
