Will I really make progress quickly, if I use Chess Mentor?
If you make progress quickly, it won't be solely due to Chess Mentor.
Why don´t you just try it out and tell us the result? 
I don't want to wast money if it doesn't do what it is supposed to do, and since so many members with diamond membership are here, it would be great if they tell us whether Chess Mentor is useful.
I like it, getting to learn other hard but interesting lessons because I'm premium , but I don't like it when I only get 3 lessons a day (because I'm gold) :(
Thanks for your comment. Did someone really train with Chess Mentor and got good results?
I don't have diamond at the moment, but I like chess mentor. What tactics don't do for you, is explain the why, the reasoning why a move is best. Sure in tactics there is only 1 best move and you try to see that. In chess mentor you learn why that is the best move, you learn what to look for. It's the difference between a book with only puzzles and a study book.
So Chess Mentor is basically a Tactics Trainer with explanations?
Not sure if that fully covers it but it comes close. In tactics trainer there is only 1 good move. In chess mentor multiple ideas can be good and the chess mentor will also tell you when your move was good, but not the specific move it was looking for. If you change explanations for lessons you get a good idea about chess mentor.
Chess Mentor also covers multiple aspects of the game; openings, endgames, positional aspects and tactics.
There is a lot more than just tactics in ChessMentor. As an example, Silman has a 300 lesson course on the "Roots of Positional Understanding". There are courses on strategy, openings, attacks,defense, endgames, and master games. It's true that there aren't that many courses rated above 2000 but if you're that good you should be able to design your own training program.
Hi, thanks for the input. How time consuming is one Chess Mentor course?
The courses range from 10 lessons to 300, so it depends. Some lessons have only a few parts to them and some have over a dozen steps, so again it depends. There was a timing component when I first joined but that's gone which means you can take as long as you want. Please be aware that as efficient as the CM is it's not a once and done process. You do have to go back and review the courses if you want them to stick. IMHO if you're willing to do the work the CM is well worth the money. If you do decide to go diamond be sure to check out IM Danny Rensch's Live Session videos as well. "Edutainment" at its' finest. Oh, if you go CM just ignore that whole sequential/adaptive nonsense. Just pick out a course that interests you and try it. There is no penalty for deciding you don't like a course and trying another. Good luck whatever you decide.
You can take the lessons in each course, one at a time. I sometimes use it when I only have 10-20 minutes to spend and I don't feel like just doing tactics. I have it set up in adaptive mode so it gives me lessons that are in my rating range (Mentor rating) and ones where I have scored less than 80% on.
Is been a while since I tried to go through one specific course so I don't recall how long a full course is.
So suppose that I "only" get Platinum, I will get 5 lessons/day, right? Then my question was wrong, it should be: How long does it approximately take to finish one lesson?
I think the 'free' lessons are random. I haven't seen a way to cherry pick them with platinum.
So you can just do 5 lessons per day with Platinum?
Anyway, can I switch from 1 year Platinum to 6 Months Diamond?
Hi, I wanted to ask if Chess Mentor is really that good. The free lessons are, in my opinion, much too easy. Will I really make progress quickly, if I use Chess Mentor? Please answer this question honestly, thanks.
