I was in huge trouble in a game lately when G1 took egypt without losing a single unit, meaning he had 1 tank, 1 artillery, 2 inf there at UK1.
My R1 opening was West Russia and Ukraine. I was lucky: I took WR losing only a single unit, and decided to discontinue Ukraine after taking every G unit except fighter, without taking a single hit myself. Then, G1 made a mixed tank-infantry build, and took UK fleet in med+ (BB+Tr) + egypt, without any losses in egypt.
I decided to try to retake egypt with india fleet + bomber, but I am not sure whether that was a good decision. In hindsight, it was surely bad: I lost 3 infantry + fighter + bomber, and G still had it’s tank. What would you do if G1 takes egypt without losses? My reasoning was that since Russia was in a very good position, I should pressure G as much as possible. But maybe I should have conceded africa for the first few rounds, and concentrated on landing in europe?
