I don't expect anyone to give up games or their livelihood etc but is this something worth learning? Do good games exist and can you get action down without heat? Everywhere I play seems to have a very similar shuffle but I suppose I don't know quite what to look for yet and it's quite possible I'm missing the key elements. I mostly play bj for comps and fun nowadays because I have bigger edges and want to avoid getting heated up, however I am always looking for things to scout in a casino and this is one.

I am studying it out of interest for now but it seems the amount of work needed to get good is fairly high and I'd like some idea if this is worth the time beforehand.
