This is a good illustration of why room clearing is almost entirely bullshit. If it works you weren't under threat. If you are under threat you're going to get your ass kicked no matter how good you are at pieing corners. Even pieing corners is ridiculous - your opponent can just shoot you through the wall. At knife fighting ranges a drywall structure won't even slow a bullet down.
