Bulgarian Gambit
From DipWiki
This Austro-Russian combination requires a careful diplomatic setup of Turkey, but guarantees to keep the Turk at three SC's by the end of 1901. Austria opens with Tri-Alb and Bud-Ser, while Russia sends the Sevastopol fleet to Rumania. In the Fall, Turkey is convinced by one or both of Austria and Russia to attempt a move out of Bulgaria, and A/R combine to dislodge the unsupportable Bulgaria.
