I like to use my bids all for Germany and all to Libya (or sz 14).
I think it gives you the most flexability since you can still bring 2 more units to Egy for an Egy Heavy attack, or you can go to Sz 13 and take Gib and save your sub (or attack sz 1), or you can also pull those units and counter in Europe if something goes bad on R1 and they leave a door open for you.
An all Europe bid cuts down some of those options since you are probably forced to send the trn and BB to sz 15 for help in Egy on G1.
I don’t like a split bid between territories b/c I still think it leaves you vulnerable in the Egy attack without bringing the trn/bb from sz 14.
I think Egy is a must win for Germany on G1 so I tend to err on the side of caution and will go extra heavy. Now with an 8-9 bid to Lib I feel a lot better with the inf/arm or 3 inf that I don’t need the trn anymore and can hit Sz 13/Gib if I want to instead.
A tran bid to Sz 5 won’t work (for Sea Lion), Russia will land 2 ftrs in London and stop the attack.
UK will have: 2 inf, 1 rt, 1 arm, 4 ftrs, 1 bom
Germany can attack with: 2 inf, 2 arm, 2 ftrs, 1 bom
Even with no planes shot down, UK should hold with 2-4 ftrs left.
