He says that he wants the two of you to kill England to start. He says that the split will be 50-50 — Belgium/Edinburgh for you and Liverpool/London for him. As a token of his good faith, he offers you Belgium from the start as a down payment on your alliance.
So you reply saying yes, but you also write to England to see what he's up to and you basically write to all the normal people. Then you log out.
Sometime later, you log back in. You have no message from England, but you have one from Russia and from France.
Russia says that France has already contacted him about going against England, and he would be very willing to relieve England of Norway so that the attack succeeds.
France says that it's all set up and ready to go. Russia has signed on. France is prepared to take on England. All you have to do is say yes and take Belgium, which France assures you is rightfully yours, and then build a fleet in Kiel like normal. The rest will fall naturally.
Do you mean to tell me that under those circumstances you would still open to Burgundy?
As Germany no, I wouldn't go to Burgundy.
As France yes, and I would say it to Germany beforehand, that I'm going to deploy an army in Burgundy. Then I see how he reacts. If he protests, whines and claims not to, then he is probably not the right ally for me. Continuous fear of a German step into Burgundy is not at all trustbuilding for France, such as the GF-alliance will suffer substantially. Paradoxical as it may sound, a French army in Burgundy stabilizes the alliance. As mentioned before, Germany can simply let an army in Munich, if he is afraid of a French stab. Important is imho that the French army in Burgundy is announced beforehand and accepted by Germany. And if not, then you want to have an army in Burgundy anyway. I had to learn that the hard way, too many games as France completely got busted cause of Burgundy.
If you're really worried about Germany moving to Burgundy while playing the Lisbon Leapfrog, you can always ask Germany for a bounce in Burgundy. That will leave your unit safely in Marseilles, ready to take Spain, and defang Germany. It kind of defeats the point of the LL, though. If your plan is to attack England, why on Earth would you start by giving Belgium over to England?
The problem is not so much the spring, but the fall 1901. Apart of Germany might agree a bounce in spring and not do so, so the Leapfrog gets wrecked, leaving France in a bad position with an open Marseilles (imagine Italy moves Piedmont) and an army in Gascony.
You may break it to a simple formula: If the trust between France and Germany is very, very high, then the Lisboa Leapfrog is the way to go. If the trust between France and England is very, very high, then the English Brest opening is just great. But how often can you trust your partner enough already in the first move, that's why these are played rarely, I presume. Otherwise you go conventionally, means Sea Lion for GF, or Northern for E with Pic or Bur for F respectively. A German-English alliance needs Italy as a helper, otherwise it becomes a long and hard thing, and the game will mostly be lost against the southern powers, later.
Your question about Belgium: Belgium is in my opinion a "weak spot", of which the owners frequently change. As long as 3 powers border Belgium, it is not a stable center. So you can easily use it for trading, and this the better the more the others overestimate Belgium.

So no problem to give Belgium to England in trade for any other "advantage". A good GF-alliance can get back Belgium easily later. Another GF advantage is that England has to bind units for Belgium's defence, which makes the GF attack even more efficient, if England falls into this trap.
As I said before, my fundamental reluctance to pair with England as France is the point that it's hard to manage an equal split of Germany. Too often I see England running off with Holland, Kiel, Belgium, and pushing for Berlin while France just gets Munich and Belgium. Worse yet, those two centers don't even touch, so you may well have to devote another unit to maintaining one or the other. Giving England Brest on top of that is just too much for me.
Plus, the technique for pulling it off is to ask for a bounce in Burgundy. Personally, I would never agree to that as Germany. Why should I bounce in Burgundy? This arrangement only benefits France. I'd much rather broker a DMZ in Galicia between Austria and Russia (Austria will be relieved) and tell Russia that I'll be glad to give him an uncontested Sweden if he opens Moscow north to St. Petersburg. Assuming Russia agrees, I can open Kiel->Holland, Berlin->Kiel, and Munich->Ruhr. The next turn, I can take Belgium by force, and get Holland and Denmark too. Sure, France may take Munich, but I'll still get two builds and evict him immediately.
Well, we need a name for the English Brest opening. I propose to name it the Celtic opening (from Brittany being one of the seven Celtic countries).
Now to the center distribution:
The agreement of the Celtic opening is no French fleets in the northern seas, and no English armies on the continent west of Denmark. So France gets Por, Spa, Bel, Hol, Mun. England takes Bre, Nor, Swe, Den, StP. The sequel could be for France Ber, War, then Austria. And for England Kiel, Mos, Sev. Or any variant of that. France hasn't to go to Italy till late, as he would need too many units for that. He can easily close the gate to the west with 2 fleets (MAO and Por resp. Spa sc) and an army Mar. For the endgame, France has even more prospects than England, but England can control him at the shore, so neither of the both gets tempted to long for the solo too much.
I think the Celtic is a very fast and safe game, provided the trust between England and France is high enough at the beginning.
