I'm a habitual blind stealer in NL Ring, but after reading NLHE Theory & Practice I'm starting to rethink it a bit.

"Concept No. 55: Unlike limit, limping first in on the button is frequently correct.... In no-limit... the equation changes a lot. Blind stealing becomes far less important in general. Because instead of being 10 percent of a big pot, blinds can be 1 percent or less of the big ones. It doesn't make much sense to forgo a shot to win the blinds when the best you can hope for is a win of ten times more. But when you can hope to win 50 or 100 times more, you might not want to steal the blinds at all. Indeed, raising in deep stack no limit is rarely intended to steal the blinds. It's used to get value for good hands, manipulate the pot size, semi-bluff, and for other reasons. If everyone folds to you on the button, and you raise, you're usually doing it because you want to build a pot while you have position, not because you want to win the paltry blind money." (Italics are mine.)

This book is really challenging my NL ring thought process. Sklansky & Miller even advocate occasional min-raises!
