Another way to go is to invade Norway with everything you’ve got its an easy win, then on non-com move 2inf to Karelia and dump your fighters in moscow.  Place 3inf and 3arm in moscow as your purchases and wait for germany to invade Karelia which he will if he wants to win.  R2 counter attack with everything you’ve got, its risky but if done well and with UK’s support with reinforcements for defense Germany will be on the run from that moment on.  Why waste days building stacks of infantry and hope for “two’s” to win the day when the idea should be to attack, attack, attack.  If anything your constant attacks will force Germany to focus more on you and less on UK, which then leaves the UK to invade WE or EU if things go as planned.

Think of it this way, do you want to react to Germany’s moves or do you want him to react to your’s!  What is the worst that can happen…you lose  :-D
