This problem basically reduces to a simple KPk mate in 21 which is solved in less than one second by Junior 6a on a 333MB PII with 16Mb Hash tables. Junior gets to a 48 move look-ahead in five minutes and picks the Kxc3 easily. It appears to be a brilliant problem but it is really just a bunch of pieces all locked up. Sounds like what China is doing to the USA. Moral of the story--Buy Junior 6a and get yourself a nice +1 GHz Athlon with a lot of RAM. Enjoy, Tim Frohlick PS Buy Junior from ICD/ Your Move
