It is not truth. I used Junior to find the mate in 12 line and not Fritz and Crafty. Fritz and Crafty are not good programs to use in complicated positions when both sides have 9 queens. > >Actually, I've been running Junior on that other position that you pasted in >that you said you gotta go deep to get an answer on, and Junior doesn't seem to >be coming up with anything (that I know of)' > >New position >5n2/B3K3/2p2Np1/4k3/7P/3bN1P1/2Prn1P1/1q6 w - - 0 1 You seem to use always the wrong program. Junior is the wrong program to solve mate in 30 when Rebel solves it with no problems. Uri
