Weasel, I think you have a good point. Having a starting range when you are just beginning is a good point, also using that range to compare against for villian is a good starting point. If you can't justify raising a set of cards, how could the villian? I think this is a valid point many of us miss in the beginning... to expand on it a bit though... once you have an initial range for the villian, even if it is as simple as your own range that you start with, consider villians actions in regards to the cards that come, the way things come, to help narrow it...

One question that was prompted to me by Code Red was "How could he continue without x in his hand?" or to put it another way "What cards in villians range would make him react like that, or lead out that way?"

I struggle with ranges too, but I think I'm starting to get a bit of it... now applying it effectively... well, that might be ranges, stage 2.
