Openings Training

I seem to get exclusively 1700-1800 positions, and eventually 2000+. I can't remember seeing positions between 1800-2000.

Pretty weird. Any reason for this to happen? My rating is usually around the 1850-1950.

Try to switch the difficulty level once in a while.

How do you do that?

There is no difficulty option on opening trainer.

LOL, sorry. My bad.

I'm not blind...confirmed
