Hi John
How are you doing this on Chessmaster 8000?
Are you using the "Solve for mate" or are you using the thinking lines window to
see the mate in 14?


If I use the "Solve for mate" it takes forever on my 333mhz, if ever. I did not
what for it to find it.

If i open the "thinking lines window" it finds it in 8 seconds, wow!

Why are the two options so differant?

Thanks,
JP
