I have a question concerning a pocket I have formed in my current AAR (this is against the AI, so I might have some hope

Reading the weakness of pockets is still not one of my strengths and maybe this can be usefull for others, too.
As can be seen this pocket is far from secure IMO (turn 41, so last turn of snow before the mud hits IIRC).
I think I can close gap 1 with moving in a mot division from Tula and moving the other mot division 1 hex to the NE.
Concerning gap 2 and gap 5 I fail to see anything I can do except to hope that moving into/crossing 1+2 ZOCs is too hard.
It there any better way to deal with gap 3 than the indicated move of the armor in order to enlarge my ZOC and hopefully prevent units from inside the pocket to push NE?
And for gap 4 I can see no way how to prevent that one except by a desperate attack by the armor on the units and lvl 2 fort in Tambov (HQ, 1 rifle division, 1 rifle brigade - would need a major wonder to work) since the armor cant move anymore and no other units are in range.
Any easy breakthroughs I have missed and any better ideas than what I have outlined above? I dont think the AI has the power/will to attack my units, so I am mostly concerned about moves that would open up the pocket.
Looking for some advice here.
Thank you.
