Hi
pawn promotion fails when Conic Computer Chess plays white (from top of board).
To be updated in cncchess2.lua (last function, bottom of the file):

function interface.promote(x, y, piece)
if (interface.invert) then
x = 9 - x
y = 9 - y
end
sb_promote(":board", x, y, piece)
end

Tested OK.
Cheers,
Eric
