The idea is simple -> deep in the search or in the qsearch I have only my 4 men
bitbases... it's good to have exact results here for some 5-men... :) I can
guess sometimes even 6, 7 or 8men results... I am quite sure that it will work,
but as I have said in another post -> when it is programmed I will present some
results... (If it works like I hope it should work...) -> in that respect kb*kp*
is now the first really interesting recognizer / special endgame I am
programming... but there is more to come... :)

Greets, Thomas
