I often get asked about my playing style. Rather than answer the question myself, I'm more interested in what my opponents say. And I've heard it all: "You're too tight." "You're too loose." "You're tight aggressive." "You're too passive." Actually, I never hear that last one, but I've heard all the others, which makes me believe I must be doing something right. Loose, tight, aggressive - my style is that I'm all of the above, depending upon the circumstances.
One essential element of playing winning poker is forcing your opponents to make difficult decisions. That's why raising is almost always better than calling - because it forces an extra decision on your opponents. To take this a step further - you'll win more money by forcing your opponents to make decisions when they are out of their comfort zones. Here are some examples: Your opponent is on your left, playing too tight before the flop. You want to punish him for this. The best way to do that is to raise more often, and be more aggressive. Either you end up stealing a lot of blinds, or he adjusts his play. If you get the blinds? Great! If he adjusts?
