I can tell you that my DD spent a year in this club and the coaches never spoke to us once.
It is completely possible that I am imagining things but...
I wouldn't be too comfortable in an environment where coaches only paid attention to their competition material kids and basically ignored everyone else.
I didn't realize how competitive and serious chess can get even for kindergartners.
Anyhow, when it comes to extracurricular activities, my approach is to let the child be the driving force. If your DS wants more chess then I'm sure he'd let you know.
Despite my reservations for the possibility of tiger coaching, I am excited for your DS that his talent has been discovered. I was burnt out by an overly ambitious piano teacher but I'm sure you'd be much more on top of pushy adults than my parents ever were. Having protective parents makes all the difference, IMO.
