Chessmaster result is close or better that mine. LLchess on Celeron 600Mhz and no hash solved in 10 moves, in 3 min and 3 sec. Mate found by selective search. It is interesting that Chessmaster find mate in 11, before 10. This is somehow resembles to what my program do when it search with default setting. There two different searches take place, and even inside of each search exist inner lower level search. It look like that mine code (even if it was done completely in void without reading any theory) still resemble in many instances with other programs. Similar result do demand every often similar working procedure to obtain it.
