A couple of things:
1) It isn’t possible for Germany to send that many planes into UK on round 1.
The only ftrs that can make it and land safely are the Finland ftr and the WE ftr. The other ftrs are out of range since it takes 3 moves to get there and they need a 4th to land. However, the bomber can reach.
The most possible units Germany can attack with in the land battle are 2 inf (or 1 arm), 2 ftrs, 1 bom.
Even with HB this isn’t a gimmie.
The 6 total planes cannot be involved in both the sea and land battle. If 3 ftrs are used to take out the UK ships that only leaves 2 ftrs that can attack the island.
2) As Russia attack his baltic fleet with your 2 ftrs.
This will kill the transport and make a G1 landing impossible.
3) Reinforce your SZ with the Russian ships.
If you kill the Baltic fleet on R1 (with 1 sub, 2 ftrs), move your Rus trn to the UK sz to help defend.
Now you have 1 BB, 2 trns to defend.
4) If you play that Russia can’t attack in rd 1, then transport 2 Rus inf to UK or land a Russian ftr on UK to help defend.
