Perfect - it seems that you're leaving your chest wide open for an attack, but in fact, that stance allows you to bring your sword up and easily block any moves with just a simple move. Quick counters would be the correct word.
Alright, so we've learned the Ox, Plow, and Fool stances. The last main one is called an Oberhut (from the roof) stance, which is a stance that easily allows you transfer into any other stance.
The stance is almost like you're about to strike down, but you're not. Raise your weapon up around your shoulders, at a 45 degree angle.
