I see when I analyze it again that it is relative and the short time that
Movei needs to see 3.Bg7 in the main line after Rxe6 is less than a minute but
still more then what little goliath needs before 1.Rxe6(my programs analyzed
other things and I could not check the exact short time then.

I still believe that the main problem for programs that cannot solve it in some
minutes is not Bg7.

I may change the value of the queen to check if movei can solve it in some
minutes.
