We are constantly working on a complete description of Milan's system. It is a comprehensive and unique approach. I do not recommend playing the system if you do not have a long-term partnership. But, it works very well with only 10 system rules which we apply in all sequences. That makes the system easier to remember when you understand the logic and the rules. The system of 2-level openings is finished and we are adding hand evaluation tests and practices that are useful to know for everyone. You can apply the 2-level structure in any natural system so you don't have to change your 1-level opening. The key is the structure after 2♣ opening. You can play it with transfers or keep it completely natural, but keep the first answers!
