Pafl: there is a big difference, if one is using a self written program, which is slightly comparable to the use of own game notations or entering those into a data base system, and the usage of a program created by others. The situation could be cleared by showing the existence of such an own engine. Thus SMIRF could be downloaded as a somehow shrinked beta from my website: http://www.chessbox.de/beta.html at Project Chronicle 2004-Dec-10.
