I incorporated some of the best parts of his world-famous Botvinnik School of Chess system and modernized it. I also added some of the best training ideas from Fischer, Spassky, Karpov, Kasparov, and Dvoretsky, etc. through my many conversations with them over the years.
I also had wonderful talks with other legends like Tal and Korchnoi, etc.
Each has his own uniqueness. I tried to improve on these ideas and added a lot more elements based on my experience over the years. This is SPICE!
