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.
