Believe it or not, this isnt a bad strategy at all...if you tune it down a bit.
Players are usually tight during the first few rounds of a tournament and you can take advantage of that. Raise a lot of (potential) hands, steal those blinds, and pick up those unwanted pots. By potential, I mean hands like Ax suited, suited connectors, any pair, etc. Fold the garbage, but be aggressive with everything else. Also, this works in your advantage when you are holding a hand. Especially in the later rounds, when blinds are high and pots are big.
If someone makes a play back at you and you have less than a decent hand, just fold it.
So, basically, you're taking advantage of the 'play tight in early rounds' strategy my doing the opposite. If your opponents are sitting, waiting for hands-attack them.
