I would be interested to see Magnum's Rumanian dash. I played with it on several attempts and could never get it to work unfortunately. (By work, meaning the pocket held so that on turn two, I could attack units in the pocket and force surrender vs having them rout out of the pocket).
I've yet to see the AI break an encirclement which has a divisional+ wide lane down to Tarnopol and to the Romanian border. In fact, you can get a division down to the border and into supply and as far as I can tell, the Soviets just don't have the MPs to do much of anything which makes it problematic for a human player too - 16th or 17th panzer is more than capable of doing it. Gamey, meh, perhaps but not anywhere as like as gamey as the whole Lvov salient taking up residence behind a riverline further east on turn 2. Trying to hold the pocket with troops would be silly as the SU does have sufficient movement points to cut off isolated or poorly positioned units north of Tarnopol.
re. your encirclement. If you're pulling that much from AGC, you may as well try for a much bigger encirclement on the AGC/AGS boundary. Leastways you've then got the armoured force to have some fun driving east quickly. Course, it weakens AGN ultimately (assuming you're trying for the Minsk encirclement in AGC) but better to go big and bold than fiddle about with half-measures all over.
