Okay, fair enough. If you only attack WRu and buy 3 arm you should generally be safe against a Kar stack on G1 (don’t know why I listed 2 arm in my last post - I usually buy 3 unless I vacate Cau completely, in which case 5 inf art arm is also sufficient to deter a Kar stack). Perhaps attacking WRu and Belo and stacking Cau is just my fetish :lol:
The issue with German bid units Ukr is that they project force into both WRu and Cau, so holding both quickly becomes infeasible if Germany puts some stuff in Ukr.
