I am a diamond member, so I can use chess mentor as much as I want. I have noticed, in doing a large number of lessons, that cm keeps bringing back positions I've already solved. My belief is that this is a kind of two steps forward and one step back approach. It keeps hitting you with the same position (interspersed with new ones) until it "thinks" you've got it mastered.
IMHO, these repeated positions should not count toward the daily total of 5.
I am a premium member, and have enjoyed chess mentor greatly. Under the listings of benefits for premium members, it says I can have up to 5 chess mentor lessons per day. I have used 14 over the last 10 months or so, and now, it will not give me a new lesson. It keeps on going back to lessons I've already done, asking me if I would like to review this lesson. What's going on? Is there a mistake with the system? Thanks very much
