That said, the maximum advantage from HCing can't really be achieved because very frequently, you are identifying a HC of 10, under the dealers 10 that is showing making the dealer hand a 20. In these frequent cases there is really only so much that you can do. You can hit your hard 17, knowing the dealer has a 20, but do you really want to hit your hard 18's and 19's EVEN though you know they are losers? If you hit these hands you risk losing the whole gig, exposing what you are doing.
So not hitting these hands, is like "cover". You are giving up some of that maximum advantage.
