I had to go through the Chapter 4 on tactics twice. Even then, the Advanced and Master level moves were difficult to spot for me. Maybe because it is hard to imagine the moves mentally on my mind. Also, loved the every explanation and analysis. My only quib – Nelson asking “all right, if you had a chance to look at” after every one of them!

Great set of videos – I am eager to see how much this improves my game on my chess.com account, but I want to finish all the modules first.
