What do you guys think about the German’s naval options on G1?
In my first game the CP player moved all German naval assets into SZ9 to take out the home fleet.
The next time around, playing as the CP, I split my navy sending two subs to take out the Canadian cruiser. This resulted in greater losses for me but it succeeded in destroying every British ship in the Atlantic, forcing the Allied player to go all in from India which made life very difficult for the Ottomans.

What do you think is the best move for the German navy on G1?

Thanks.

Two quick questions.
First,  if no destroyers are present, do subs get their suprise strike every round or just the first round of combat.
Second, if an aircraft carrier adjacent to a friendly land teritory is attacked and destroyed by only subs can the fighters move to land or are they destoryed at end of the attackers turn?
