@Sargmacher&IKE: I don't understand why you are so depreciative of the Key Lepanto. To me, the sginal is obvious (if not too obvious). Two reasons:
If Italy wants to attack Austria, he moves Ven-Tyr, Rom-Ven, to follow up Tyr-Boh, Ven-Tyr. Or he moves Ven-Tri, Rom-Ven. So when he moves Rom-Apu, Ven-Tri, he is either a complete noob, or he wants to play a Key Lepanto. Considering this was a 7000 point game, I think we can rule out the former.
Second, if you are Austria, you are out of options. You've willingly let Italy into Trieste, and now you should hope you're not getting screwed over. You can fight with Italy, but that fight is hopeless. Italy's already advanced on you, and RT will gladly see a pointless struggle around Trieste. So you have to go for the Key Lepanto.
Now, If Italy decides he wants to kill you (which he certainly can at that point: Ven S Apu-Alb!), you're dead. But then again, in a gunboat, where Italy plays anti-Austria, you're dead anyway. If you do not trust Italy's intentions/expertise, you shouldn't have opened Tri-Alb!
In other words, assuming all players are infinitely intelligent, I believe this opening assures a Key Lepanto will be played. And we all agree a KL is the best that can happen to Italy in Spring 1901.
