As a German player, I have noticed the importance of Kiel. In an FG vs. E it is the most important of all the German providences.
Your moves could go as follows:
Spring 01
F Kiel to Denmark
Fall 01
Assuming you have taken Holland (Ber-Kie-Hol) you should place a
fleet on Kiel and assuming that you moved your army out of berlin place
another fleet on berlin.
Spring02
This is interesting. move fleet Kiel to Hel. Denmark to Skagarak. Berlin to Baltic.
fall02
Baltic to Denmark
On your next move you will be able to take the North Sea.
From there, the possibilities are endless.
It all revolves around kiel.
