My thought was to take the UK cruiser from SZ112 and put it in SZ110, move the transport from SZ109 to SZ91, and add 1 inf to Gibraltar or move the Algerian french unit over 1.
It forces the Germans to attack SZ110 on G1 or this happens.
The Brits move Egypt navy with inf and arm to SZ92, SZ110 goes to SZ104 to block.
It forces te Germans to attack SZ104 on G2 or this happens.
UK moves SZ91 and SZ92 to SZ109 (a German block on G2 in SZ104 would be taken out by RAF and everything NCMs) adding 3 inf and an armor to the UK on UK2.
If the Germans take their subs from SZ109 to attack the block in SZ104 on G2 that adds more ipcs for the UK to spend.
It also leaves the uK navy to worry about after the Germans take London. It makes it easier for te allies to kill the German fleet after the fall of London.
It still leaves German the option for sealion but reduces the odds slightly.
It doesn’t pose any real threat to Italy.
It gives the UK some more options of play
The UK could take brazil, Persia, and Iraq to gain more ipcs to put in London too.
