Avoid putting yourself into situations where you have to guess like that. If you are unsure of which sword to use, it is generally safe to IAD j2DD. Of course that puts you closer to the corner, which is something you want to avoid. If push comes to shove, you can take the fight to him by dashing forward and initiating pressure with a move. It's sort of hard to explain exactly what to do without seeing you in action and seeing what your habits are.
You never made me.
