The main problem with the chessbase interface is that it does not let me to put the position on the screen. I do not know if the engines have problems with the illegal positions because I cannot get them to analyze the position. There are many engines for chesssbase and maybe part of them can analyze the illegal positions if they have no chessbase enviroment. Chessmaster and Rebel also do not let me to put this kind of illegal position in the screen. Uri
