I'm a zerg player and on close-spawn situations, I will definitely cheese. especially to terrans.  
I see on forums like gamefaqs, etc and I see a lot of complains of cheese, saying it's dirty, unfair, cheap, not sportsman-like.
But to me, I think it's just another strategy. Like, there's always a lot of things you can do to counter, like scout or counter-cheese or something, right?

What do you guys think?

I have my sc2 buddy who plays terran and he's really pissed off about the baneling bust (Which I always do to terrans), and to me, there's a lot things he can do to counter it, like putting bunkers or factory/rax behind the wall-in supply depots.
