Steve, Thanks for doing this ... a couple of comments.
1. "Lastly, the Germans can position a wimp fighter near the Baltic Sea, planning to send it into the zero section box with the German convoys should the Allied player send surface ships into the Baltic on the second impulse of the game." -- I don't believe this is possible. That is, with Germany being on the receiving end of a "surprise" impulse from the Brit's and French declaring war on her, I don't believe she's allowed any air reactions to their attacks on the second impulse. Of course, the fighter could react during any future allied impulse.
2. wrt/Invasion of Denmark. What about the threat that the CW will intervene directly with land and air units? Especially if the British BEF is at sea, or in port, and Germany fails to take control of all Danish hexes bordering the North Sea. In this case, assuming Denmark is aligned to the CW, Gort could disembark from any box in the North Sea and then support another corps and division disembarking on top of him. Add to that the threat of the CW moving an air unit or two to that stack and now the German player has a headache of major proportions. To prevent that I only (always) invade Denmark such that I can flip control of all Danish hexes bordering the North Sea to German. Flipping control, for me, takes precedent over capturing Copenhagen if necessary.
