Nice defence, though I think his northern opening was a little limp -- he missed Riga (I have a well known aversion to the Riga gambit caused probably by my view that bombing Kuessara with 250 Ju-88 and He-111 as a way of landing troops unopposed in Riga feels a little weird -- still, I have now used that gambit in my latest game and must confess, it's a good move); also missed that southern crossing of the Daugava where the paras are.
Remember that on Turn 2, his panzers will still be carrying supplies of fuel from Turn 1 and will have juicy movement values (not 50, but not 16 or something similar). Be interested to see how he deploys the new Pz and Mot divs from 1st Pz Army.
Good start -- glad I am not playing you
