Yes, if 1600 means average clubplayer(+) you should win with easy, at least
games longer than 10 minutes.

You could try to create a new engine with Shredder Classic and when you comes to
the dialog with author's name etc. click on parameters and do the changes. Then
change the name to f.ex. Shredder Classic 1000.

After this you can look in the (fritz) enginefolder for the file 'Shredder
Classic 1000.uci'.

The option section should looks like this:

[OPTIONS]
UCI_LimitStrength=true
UCI_Elo=1000
Use Tablebases=false

When you load this new 'engine' you should see that it never get high on the
ply. You can also notice if you bring up the task manager that it use no cpu
power.
