"Another key to this is what YOUR raising range is. If you are constantly raising in position with a really wide range, people are obviously going to be more likely to play back at you and in that case you expand your calling/4-betting range a bit. But make sure the opponent playing back at you is capable of that kind of play or you're going to be up against the nuts far too often. "


For example, if you are raising on the button with 30% of your hands, an opponent might start reraising with something like the top 15% of the hands, which is probably a wider range than you have in mind as a default holding. If you, in turn, fold everything except the top 1.5%, i.e QQ+, to the reraise, the opponent is coming out ahead in the long run.

However, you might have wait quite a few hands to get that kind of read on someone. Against an unknown, figure that he will play tighter until you see different.
