[Black winter day]

So, i am finally finishing NLTP and i encountered 2 strange concepts, 28& 29 on pages 266/267.
Basically, what the book says is that with a strong hand (they give KK as an example) and 100BB stack (example - 1000$, 5-10NL), you should either make it like 30$ even if there were 2 limpers behind or overbet to like 120$ to cut down villains' implied odds, cause if you raise to 60-70$ you are basically telling the opponents you have a strong hand, but give them implied odds to outflop you.

They call the 30$ raise a pot builder, together with your positional advantage.

And in the next concept, they advocate to often make minraises, mostly when you have double stacks and hand that plays well in multiway pot in position, like ATs or SC.

What do you think about this stuff?
Seems pretty much the opposite of what is considere the standard preflop raising advices.
I'll pm David Sklansky with a link to this thread, would be interesting to see what he has to say.
