Type of player?
I pretty much adjust my game to the other players on the table. In other words, if I'm in a game where I judge the other players to be mostly tight, I'll play loose, but not too loose. In contrast, if I judge them to be mostly loose, then I tighten up, but not too tight. I've found that if I play tight early in the game then I can get away with bluffs more often later in the game. And if I play loose early in the game then often I can trap my opponents more successfully later in the game.
You do have to keep a lookout for good players though. They'll often switch back and forth between loose and tight. Those who never change their play are the ones you can usually cash in on, though they do sometimes get lucky, or you get unlucky, depending on your perspective.
