@Maxiheimer:
Supporting Yunnan is still better than going north in my opinion.
Ok, I will take a stab at the strategic plan that Yunnan is more important than the threaten northern China plan that I proposed with the Communist Chinese have arrived plan.
Lets set the board this way with a standard opening move by Japan.
They take Yunnan, Hunan, Anhwe and Charar.
Japan has a huge stack of Air power sitting in Kwangsi.
China Turn 1 Moves ALL their forces back to Shensi and forms a fortress. They have 15 INF + FTR. The Burma road is toast for now and no need to send troops into the vortex of death of Yunnan. So, next turn they will be able to build 2 INF with their 8 IPC.
Now Russian has the Chinese Communist army formed up on R2, ready to move in.
Japan on J2 decides to take Suiyuyan, Hopei, Kweichow and Szechwan. Now, Japan though has to decide on how many land units to put into these territories. Remember Japan can not reinforce with air power at this point. All 4 territories can be counter attacked by China if they desire.
At this point a little table talk from the Russian player to the Japan player might just give you an edge. You point out to him that Russia has 11 mech + 2 arm and 1 tac ready to reinforce Shensi on R3 before J3. Bringing up the defense/Attack of Shensi to 17 INF + 1 FTR from China and 11 Mech +2 arm + 1 tac from the Communist Chinese. That is a titanic stack of units sitting right in the middle of China for Japan to have to deal with. When R3 arrives you DOW on Japan and move your stack into Shensi. You retreat to the corner of the room where the keg of beer is at and pull a 32OZ mug of beer and see what Japan does on J3. Of course regardless of his moves you chuckle and talk to your ally who is playing China in the side room just to make Japan sweat it out a little. Of course do not neglect to mention that the communist also have 18 INF sitting in Amur ready to pounce.
Now what happens from this point on is pure speculation and totally dictated by the “board” so no need to continue what to do after you rally the Communist with the Nationals in Shensi.
Here though is the dilemma for Japan.
They really want to take Calcutta because of the VP city.
It will take them a lot of effort to take it though.
China though is a greater threat to Japan than UK Pacific because China not contained can earn more IPC than UK Pacific in the early to mid point of the game.
China now has enough troops that they can take out lightly defended territories and “can open” for the Communist to blitz even further towards the coast.
China can retake 2 VP cities if not stopped and thus make knocking out Calcutta a mute point.
At the end of the day China is a greater threat to Japan than UK Pacific can ever be in the early to mid point of a game.
That huge stack in Shensi has the potential to wreak a huge amount of damage on Japan if they ignore it and go all hell bent on India.
