Dear TPE Pros

I've recently been reviewing my MTT sessions filtering for hands between the 20 to 30 BB range. 

I'd like to share a (fairly normal) pre-flop spot & ask a few quesitons about how the hand/our actions should change based on a few adaptations.

Villain (Tripleee) was playing 21/14/10 over 56 hands. 
His raise first in was 0 (EP) / 38 (MP) / 0 (CO) / 50 (BTN). 
Cbet% was 50% over 2 hands & FCB 50% over 2 hands. 
Villain has 22BB 

I was playing 19/17/9 over 56 hands
My raise first in was 17 (EP)/ 18 (MP) / 67 (CO) / 100 (BTN)
CB% was 100% over 1 hand & FCB 100% over 1 hand 
I have 21BB

The players left to act are normal regs, no big fishes or aggro/squeeze happy players left to act.
Every player left to act has around 30-45 bb, so no re-shove stacks 

The hypothetical question here: Do we have a flat calling range in this exact spot?
–> I think not, maybe with KK or AA if we're trapping & expect our opp not to perceive this to be very strong

My question: What has to change for us in order to have a flat calling range here?
 –> Could we flat with these exact stack sizes if we have a good read on our opp & on how he plays postflop? (= hypothetical, not based on the info we have of this opp) 
  –> He plays fit/fold, checks when he's ready to fold, bets if he has it? 
  –> He usually gives up after his cbet gets called –>  floating & betting if he checks the turn has a high succesrate

–> If our opp isn't that 'easy to play against', what has to change for us to profitably flat in position with this exact hand? (when no squeeze-happy players or re-shove stacks are left to act)
  –> Effective stacks: more like 25bbs? 30 bbs? & why? 

–> How does this change based on the hand we would like to flat? 
  –> SC's & small pairs? If we expect to get at least 10x the amount of money we have to invest (= the call) & this obviously depends on the opp you're facing (will he keep barreling when you x-call or will he not invest a lot with a marginal made hand). We probably don't have this too often with 20-25bbs
  –> Middle pairs? Are we going to face too many tough decision with a 25bb stack when we flat here & should we thus simply fold pre to the open?
  –> Suited broadways that aren't the nuts (KQ,KJ,KT, QJ,QT,JT): We aren't really happy getting it in postflop here with only toppair for 20-25bb, so should we just fold our hand? Should we wait to play it when we're deeper?

I know we can still 3b these hands versus a player that opens a lot & always folds or 4bets with a very nutty range (top 5%) but this is a purely hypothetical post where I would like to talk about flatting IP with 20-25/30BB range & what (effective stack size, hand strength, opp's tendencies pre-flop, opp's tendencies post-flop,… ) should change for us to profitably flat IP.

Thanks in advance & good luck at the tables!
