The past month I have been working hard on my four new openings. I have become a premium member of Chessable, who have a nice concept of training with spaced repetition, combined with interactive study books. That might be the direction where chess books will be heading in the future.
Rote learning of variations doesn't feel very effective. It is the lazy man's way. If you are good at rote learning. OTOH, doing nothing at all isn't very reassuring either with four totally unknown openings.
Tonight the new club season starts. I look forward to see the openings in action. Once I feel confident with them, I will continue to play for guinea pig with our new tactical transfer system based on analogies.
