After checking the website, ICN mainly cooperates with schools to organize after school chess classes or chess clubs. There are already 27 schools under its banner, most of which are public schools of the PS series. PS 33 (aka Chelsea Prep) (photo) is probably the most famous one. With such a huge scale, there must be a coaching team. But because it is not directly under a school, the coaches are not necessarily the strongest, and the student stars among them are not the strongest. But it has a lot of activities. In addition to after school, and Marshall's class, there are also monthly training camps, and several tournaments every weekend. This has built a good mass base for the popularization of chess.
ICN will definitely continue to expand, and maybe one day it will be bought by Play Magnus like Silver Knight (DC, an after school institution in the Pennsylvania area). This is a little prophecy of mine.
