A mate in 6 is always better than only +17. I guess this also depends on the
settings you use for blundercheck. If you set the eval difference to 100
(centipawns) Fritz will give other suggestions/comments with +10.xx as better
than +8.xx e.g. I don't know if there is a number that avoids these "mate in X
is better than +20" comments, however, I'd like to see if I left out a short
mate. :-)
