IPM?
Another example of why this game will never be won, except in lucky situations, by gimmick moves that either “win” the game in 3-5 rounds or in the first round. Its called Infantry Push Mechanic and it has won every game that its used in. Read the boards of some of the other games to find out the details.
Even if you take Moscow for one turn,unlikely but possible, you have no supply line that is worth it to back it up. Your victory is only won for a round and then Germany is a hollow tiger, and so is Japan. You have hamstrung both major Axis powers to do this. No Atlantic wall, no reactionary force, no win. Not with sane allied builds and a strategic outlook.
I just played at a Convention and my team (of course we have played extensively together) would have won based on IPM, the constant supply of fodder without the loss of high powered units. The other team conceded, but it was a given with time considering their waste of high powered units…
