Good point. How can I use it to help with opening preperation?
Fritz 11; is it useful for improvement?

a crusade going on right now, calling people who are using an engine or playing blitz patzers, insulting people and so on

to improve u have to understand and learn ideas.
Program like fritz just show moves (not giving a reason why, the evaluation doesnt give ideas), not ideas, so i think it is useless...
Can Fritz 11 help 1600-1800 rated players improve? Also how might I best utilize it's functions?
