@Bean:
Why is Russia 1 excluded? Any player continues to wax and wane between the possible Russia attacks and strategies…
Because in most cases, Russia has the same board configuration each and every time they go to make Russia’s first move.  That means they can pretty much make the same attacks, buy the same equipment, etc from game to game with the only alterations to that being a difference of players’ opinion as opposed to Japan or Germany having to move to counter a KGF/KJF or America and England facing a large German fleet instead of a large German army, or what have you.
America, on the flip side, is the least able to build a “pat” routine for USA 1 because Russia could have done splendid, Japan could have left the SZ 52 in tact, England could have fallen to Germany on G1, what have you.  There’s no way to know what the board will look like on USA 1. (You can pretty much guess what it will look like and be right most of the time.  China will have fallen.  SZ 52 fleet will be gone.  Russia will be out of Karelia but have W. Russia.  England will be nursing a black eye in Egypt, but have fleet and units around for the most part.  Germany will be stacked in E. Europe, etc.)
