I feel like a huge leak in my game is that I tend to find myself in positions where I get like 40+BBs all in at the middle of tournies where I am close to certain that I am flipping for huge stacks. 

For example, last night this situation arises.  Now some background…  The villain here had shown down an overshove like this 3 times:  66, JJ, and AK.  However, just the last orbit, I opened K10s, he 2.5 reraised me, and I 4 bet shoved him into a fold with like 29 bigs.  My read was he felt like a made hand (AK may feel to be, in his opinion, “made”) was just to shove, a 3 bet signaled weakness.  We are well past the bubble.

My image should be kinda tight, even though I shipped like 4 times the last 30 minutes since the bubble, but they were when I was massive shorty with like 15BBs and had limpers/ open shoved.  Hadn’t shown down junk or even seen a flop when I raised.  Since then, I double with QQ when I called an 18BB shove of AQ and I held.

Questions:

1.  In the future, if my reads tell me that this hand is like 90% a flip, is this a standard call?
2.  At what stack size (how many bigs) does this call become standard regardless of reads (imagine I had just been put at this table)?
3.  At what BB level are we comfortable taking a flip, even though we never KNOW we are flipping, if a player has his card face-up?
4.  Do you call here?
