Thanks, for your kind words. What I implemeted as "cook finding mode" is already
possible with the UCI protocol. The UCI protocol has the "searchmoves" to
restrict the choices to search in the root position. An UCI GUI could easily
"drive" the engine, to only search the moves that are not after bm, and you have
the same functionality given by the cook command in Yace.

Auto play is also possible, with UCI and WB. However, the GUI would need to
start two instances of the engine, which has some disadvantages. Most resources
will be needed twice, compared to an auto play mode inside a single engine. UCI
mode also has the "info string" which can easily support all the stats yace
shows in console mode. WB has a similar feature, that unfortunately at the
moment is practiacally of little use, because it will always pop up some
message, where you have to click or hit ENTER (from memory, I did not check it
at the moment. I think it is "telluser"). This could almost be considered a bug
of WB/Xboard (the GUI, not the protocol). The protocol could be enhanced here,
too. The functionality is there, in principle.
