I was playing a live game last night and some dude started throwing live straddles onto the blinds.

What's the logic here? Why would you want to raise the blinds before you even look at your cards? Why wouldnt you wait to see what you have, and then raise?

The only thing i can think of to justify this play would be for the sake of projecting an agressive table image, which didn't really work, it just made the guy look like a jackass to me.
