Both openings mentioned by Steve Knight presume a strong
Austro-Italian alliance.  Both go so far as to presume Austria will
sacrifice a build for Italy's sake (the supported attack on Trieste in
Fall '01 in the Three Fleets will likely deprive Austria of Greece).
Even if Austria is willing to make that sacrifice, it would (or
should) do so only if the alliance as a whole is strengthened.  This
is the case with the Key Lepanto, as Italian forces supplement
Austrian forces in the East in a timely fashion.  However, I argue that,
even if Austria CAN trust Italy completely, the Three Fleets is unsound.

The Three Fleets leaves the Austro-Italian alliance with only two
supply centers gained in 1901 (Ser & Tun).  If the critical issue is
to produce four allied fleets in Winter 1901/1902, this can be done by
having two Austrian and two Italian fleets as well as by having three
Italian fleets and one Austrian; moreover, as Austria can also gain
Greece in a more conventional opening, Austria does not have to give
up the build of an army to do so.  True, there is a "wasted" Italian 
army, but substituting no army at all for the "superfluous" one is no
real gain.  In short, an Austrian fleet built in 1901 can provide all the
advantages of the Three Fleets without leaving Greece open, so whither
the Three Fleets (if your answer is that Italy cannot trust Austria
with two fleets, ask yourself if such a trust is any less prudent than
trusting Italy to disband A Tri in the Three Fleets)?
