This is belated but I didn’t have the time to really respond before. As others have noted, Booper lost this on G1. That is partly that I had great dice, but also that you had spread yourself thin enough that with the scramble, I could do real damage.
I’ll pretty much always scramble on 110 if it makes a modest improvement in the TUV exchange, and if the battleship isn’t there. There is some risk of the dice going south but in most cases, I will hit some German air and I’m willing to trade against them at a loss. Another reason to scramble is simply that you get the reputation for scrambling and your opponent thinks twice before going for both 110 and 111. So in a certain sense the odds of this are even better for the allies than ABH identified.
This being said I felt that despite that G1, I was in tough and that I was one mistake away from losing for much of the game. A couple of mistakes on my part contributed to that I think, but booper’s play was great. Very hard for me to get meaningfully into Europe.
As I mentioned in our chat, I think you had an earlier chance to take India, but lost it by focusing on China. This gave me a chance to move allied air (and ground units) to India in time to shut that possibility down. Had you gone for it, it might have changed the outcome.
