I think @ 9BB, you want to be open jamming or folding with these types of holdings. 
You make most of your expectation from the fold equity, but they're never doing terribly equity-wise when called. 
Min raising may induce a 3b jamming range against which your equity is not great. 
Likewise, limping will likely be jammed over pretty wide @ this depth and you will be folding a decent equity share if you limp fold. 
 
If you fold, you will end up with a stack worth (S-0.5).
If you jam, villain will call with some range C, against which you have e equity. 
So when he folds you will win his BB, and end up with a stack worth (S+1). 
He does this with frequency, (1-c), where c is the % of times he calls. 
And when he calls, you will end up with a stack worth 2*S*e => your equity share of the final pot. 
So your expected stack after jamming = (1 - c)(S+1) + c (2Se)
Therefore jamming is better than folding when:
(1-c)(S+1) + c(2Se) > (S-0.5)
 
Consider what villain might call a jam with @ S. 
For example, @ 9BB, we might expect villain to call with something like: 
[A,KK-22,KQ-K7,QJ-QT,Kx6x-Kx5x,Qx9x-Qx8x,JxTx-Jx9x,Tx9x].
 
Against this range, JxTx has e ~ 42.7%  & c ~ 32%
@ 9BB
(1-c)(S+1) + c(2Se) = (1-0.32)(9+1) + 0.32(2*9*0.427) = 6.80 + 2.46 = 9.26 BB
and
(S-0.5) = 9-0.5 = 8.5 BB
So with JxTx @ 9BB, vs this assumed call open shove range, we do (9.26 - 8.50) = 0.76 BB better by open shoving than by folding. 
(Note in this case it is also +0.26 BB expected profit from your starting stack of 9.0 BB at the start of the hand)
 
Consider a weaker suited connector at the other end of the scale: 3x2x
Against the same range, 3x2x has e~ 33.1% & c ~ 33.6% ~ 34%
@ 9BB
(1-c)(S+1) + c(2Se) = (1-0.34)(9+1) + 0.34(2*9*0.331) = 6.60 + 2.03 = 8.63 BB
and
(S-0.5) = 9-0.5 = 8.5 BB
So with 3x2x @ 9BB vs this assumed call open shove range, we do (8.63-8.5) = 0.13 BB better by open shoving than by folding. 
(BUT note in this case we have 9.0 - 8.63 = - 0.37 BB expected profit from your starting stack of 9.0 BB at the start of the hand)
 
Also note that in both cases your fold equity is worth about 3 times that of your pot equity vs villain's call open jam range. 
 
You can repeat this process for different villain calling ranges and all the other hands in your range not covered by the 2 examples above to explore the profitability of each of your options at various stack depths. Varying villain's ranges & the effective stacks modelled and observing how it affects the range of hands you can profitably open shove is useful for formulating maximally exploitative strategies in the extreme end game of HUSNGs. The results vs some ranges of particular villain tendencies will shock you (hint your pot equity is rarely worse than 35% so the results are largely driven by the width of villain's calling range). 
 
This will certainly give you something to work on :)
