@Subotai:
@ Bardoly, a German naval strat in Classic, Revised, AA42 and AA50-41+42 is ineffective, plain and simple.
While I think we are in basic agreement about AA50 principles, you are overgeneralizing when it comes to Revised. Granted, I wouldn’t play a German navy or a KJF against a Top 20 TripleA ladder opponent in a 9 bid ll scenario. But I know that approximately half of the Top 10 rated Revised players on GTO regularly buy an AC+ G1. Not just for fun…they believe it is the optimal strategy. I also feel certain there are viable KJF strategies in Revised because I’ve played hundreds of games of Revised and still find myself losing to a friend’s KJF via PBEM (for starters see here http://www.axisandallies.org/forums/index.php?topic=15579.0).
AA50 with NOs is a different game entirely. Strategies are impacted by different unit dynamics and the huge impact of national objectives. Re. a German navy, granted that holding Scandinavia prevents a Russian NO. However, if Germany uses a land strategy, then Russia won’t get this NO until late game at best. So far I’ve found that if Germany plays naval in AA41, then the fleet usually dies around the time Russia wants to get offensive, so it tends to work out perfect for Allies.
That leaves the Karelia NO. The fleet helps contest Karelia. But if Allies want Karelia, they can try to stack it. Keeping the fleet alive and buying the units necessary to dead zone Karelia seems tricky.
