OK one more try, with some adjustments.
G1: Build 4 trn.
Attack SZ 110 with 1 sub, 1 battleship and 4 tac bombers and 2 fighters. Lose the sub and battleship first. Attack SZ 111 with 2 subs, 2 fighters and 2 bombers. Still attack the Canadian des and trn with 2 subs.
As usual, all land units in range attack Paris except 3 inf and 1 art from Belgium, which attack Normandy.
Take Bulgaria with 1 inf from Romania and Finland with 1 inf from Norway and attack Yugoslavia with 6 inf from Greater Southern Germany and the tac bomber and tank from Poland and the fighter and tank from Slovakia and 1 tank from Romania.
Non-combat: Move cruiser and trn from SZ 114 to sz 113. Land 2-3 fighters in Western Germany. Land tac bomber from Poland in Western Germany and fighter from Slovakia in Belgium. Land all other planes in Belgium.
Place 4 trn in SZ 113.
UK builds 9 inf, Italy attacks UK cruiser and/or des if moved to block, on G2 Ger builds 1 trn, 1 cruiser, 1 aircraft carrier, the rest bombers. Ger attacks with 5 inf 5 art plus planes plus cuiser bombardment. Retreat planes to aircraft carrier and Belgium when it looks like you will lose more than one.
Place Ger units in SZ 110 from Normandy factory.
UK builds say 11 inf. Ger builds all inf and tanks to go against USSR, attack London with 6 inf, 6 tanks and all planes and 2 cruiser bombardments.
In regard to UK using their med fleet by taking out the Italian des in SZ 96 and then non-combatting to SZ 92, the Italian fleet can attack them there because they did not do Taranto. If UK builds an airbase in Gibraltar and lands planes there to defend the med fleet, that is less defending London.
