Version 3.0.1 of Chess for Android is available at the Android market and as direct download. It introduces the first, albeit simple support for the Chess Engine Communication Protocol (XBoard/WinBoard). Many features that are already supported for UCI (e.g. options setup, infinite analysis) as well as some XBoard specific features (e.g. resign) are still missing for this first version. I hope to add these features soon. Nevertheless, it is already possible to run tournaments between engines.
