Your understanding appears correct to me. GNU Chess invoked as a separate process via the Winboard interface is mere aggregation, and doesn't affect the licensing of other code distributed with it in this fashion. My understanding is that such distribution, from a licensing perspective is the same as distribution GNU Chess itself. As you'll be distributing GNU Chess, you will incur obligations under the GNU GPLv2, to notify them of their rights to GNU Chess, and to give them a copy of the source code for GNU Chess (plus any modifications you make to GNU Chess) on request. But this doesn't affect any other applications you distribute alongside. You are encouraged to distribute your GUI under a free software license, but there is no obligation.
