In both our games the American Pacific fleet got crushed in the Caroline Islands. That location is a death trap, there are just too many ways to get there and with the way carriers can reposition to pick up planes, Japan can concentrate alot of fire power there even when it does not look like it.
In this game you could have really messed with my plans by having the Russians in Moscow fall back and link up with the units coming in from Siberia instead of standing and fighting. Granted you lose Moscow, but that was going to happen anyway, this way you would have had this huge army running around in central asia, which meant the bulk of the German army would have had to stay their too, giving the UK more time to fortify Cairo.
When I was messing around with Triplea playing against myself, I found that the only way to stop the G1 onslaught from taking Moscow was to shuttle planes in from Scotland and up from Persia (nice place for an IC, imho).
I tend to be too conservative when I play the allies, so seeing your more agressive free wheeling style was helpful for me to see, I hope I learned something for our next game.
Good luck! (or average luck for both of us) in the next game
