(take care, that 2 positions are mate for black after white´s first move) The other 4 positions are a little bit harder in brute-force mode for ChestUCI (at least on my slow notebook), so I´ll try them with ChestUCI´s special-mode - of course this could also take some time, but I´ll post my results when I´m ready with it.
