Semi-thread hijack, but this is an example of what I've been trying to get at in the BC recently. You can try to find out what to do in a wide variety of situations, or you can spend time away from the tables thinking about spots and learning the WHY behind the advice.

It would be very easy to answer "Yes play a wide range because villain is bad/you're ahead of his range/whatever" and blindly follow that advice. However if you think through the situations, think about the kinds of villains you're familiar with, stuff like that, then you can come up with a much more well directed adjustment for ANY specific villain.
