   I noticed that with most Fritz programs, when they see a mate, they STOP
calculating and play the move, even if there is a quicker mate to find. But on
its next move (in a game) its recalculates everything... Opposed to that, Genius
keeps searching and does find the faster mate. After the mate is found, it plays
all the moves instantly to the mate, while Fritz has to recalculate the mate at
every move. You apparently cannot make Fritz contimue calculating after it found
 a forced mate. Well there is maybe a way, in infinite analysis, if you add up
new variations to be displayed in the window, it continues calculating for these
and as it goes deeper, the first line (the one or those with the forced mate)
are also updated and so it will find the fastest mate, eventually...
