The new UCI2WB 1.9 now also supports the UCI 'searchmoves' command, so that you can exclude moves from analysis with UCI and USI engines that support this command. A Windows binary of UCI2WB 1.9 is now included in the WinBoard beta package (together with a WinBoard version that supports move exclusion).

Source code is available from my on-line repository . It should compile for Windows as well as Linux, according to the instructions in the README file.
