Hi Frank,

Thanks for your report. I think that the problem comes from the way GNU
Chess is
invoked.

When you want to run it from XBoard, you must use the --xboard flag. The
manual
of GNU Chess (info gnuchess) includes a couple of examples that show how to
run
XBoard from the command line specifying GNU Chess as the first chess
engine.

For instance:

xboard -fcp 'gnuchess --xboard'

If you just simply type

xboard -fcp 'gnuchess'

the interaction between both programs will not work.

The way XBoard invoked GNU Chess can be seen in xboard.debug. You should see
something like:

StartChildProcess (dir=".") gnuchess --xboard

In your attachment, the --xboard flag is missing.

Please let me know if this is of help to solve the problem.

Regards,
Antonio
