I am not a proffesional player by any means, but can share my experience..
the most beautifull feature of icmizer is SnG coach - it has a ton of pre-defined quizzes for various tournaments types on multiple networks.
But before starting these quizzes one should grasp the basic understanding of the reasoning behind ICM-driven decisions. Personally I started with 3-max spots in SnG 9-max tournaments and went through "standard" situations, like:
- BTN, SB, BB have the same stacks : 3BB, 5BB, 7BB, 10BB, 12BB
- BTN, SB have the same stacks, BB has the stack twice as large as SB/BB one.
etc. etc.
and once this foundation is built, solving quizzes can solidify it.
