ok so it helps me see some silly blunders mainly. I signed up on diamond as a beginner to get the game review. I guess I still have the benefit of puzzles and lessons.
After a review of my last game where I got mated, I wish it simply said move your knight to a dark square to avoid mate by bishop on white diagonal and queen. that's a lesson I had to analyse myself and I think it is such an easy pointer.
Yes look, in my first few games it was nice then it was capped and I wanted it back. Did the free trial. It's okay. Not expensive for one year. And it is pretty efficient to use.
