Played against AI on revised - @redrum it was pretty fun and some challenge : )
There were a few interesting moves and some adjustments that could have made the AI stronger. Save game attached and below called out some of the interesting moves made.
Round 1: Germany uses a tank to capture archangel. There is only a single 50/50 change that it'll be an even trade assuming the tank can kill an infantry while on the defensive. Meanwhile AI then loses the tactical advantage of having a tank near the front line. Attacking the lone tank is a good trade for russia provided the air power and can do so with better than a 50/50 chance of winning.
Round 2: Japan lost Manchuria with a factory in round 1 against improbable odds. Instead of retaking in round 2, it attacks Buryatia
Round 3: Germany does SBR in Karelia instead of attacking BeloRussia with one infantry and bomber.
Round 5: Japan buys an AA gun even though there are no bombers in range
