Symbolic is an extremely interesting project, and I hope you succeed in creating
a super strong engine with your unusual approach.  However, forced mate
positions
like this one are not a good way to measure progress.  Solving them quickly is
easily
achieved by more conventional methods (the above position is solved in 7 plies
and
only a couple of seconds by Gothmog), and does not necessarily imply high
playing
strength in normal games.
