When I see you, I'll hold fire, and then get-around so that I can shoot your side, when I'm bow-on and have the advantage. You see me, and you begin turning. I will slow to 3/4 or 1/2 speed, and shell you in the superstructure. Once you compensate with your aim, I'll slow to 1/4th speed, or even stop and reverse. However, once your secondaries start opening-up, I'll go full-speed. I'll still shoot you, because my goal here is to deal as much damage to you before I go down. With a not-insignificant amount of luck, I'll even ram you.

You are assuming he plays like an idiot. I don't know where you fathom your chance to win an engagement with a Großer Kurfürst in an Alabama.
