@taamvan:
Youre saying its a “tell” (indicates what your opponent intends to do) but how can it be, when you do it every game, no matter what your Allied plan is?
If Japan enters the USSR without killing those 20 pieces, awesome, now they have 26 new problems on a front pointing away from the real war.
Good point.
Russia on R1 should pull all their troops west for one turn. DO NOT LET JAPAN attack your Eastern Front in Amur. Russia just needs to keep presenting a threat on Manchuria. At some point, as the Russian player you have to decide when to really attack them, usually R6-8.
Stacking Amur on R1 sometimes has the effect of Japan going J1 on the Russians and totally destroying all Russians East of Moscow. This is usually no bueno for the Allies.
** Side Note **
I have never scene the Axis lose when Russia stacks Amur and Japan goes J1 on Russia and kills off all Russians east of Moscow.
