The common theme is that villain makes a play for the pot where he has very few outs to win (4 or less is my threshold here and its usually AI on the turn so his equity to drops to 8% or less). The pot is greater than 100b OR villain makes an overbet / commits way too many chips far behind. As such there is more on the line than a standard 100bb stack. 

My composure has been really good the last two weeks, these two hands stand out because I was completely aware of my mood change and wanted to stop my session immediately. Since, my emotional reaction to these two hands were quite substantial i think they deserve attention.  

Feelings: are that of dismay and disappointment. As opposed to anger/frustration.

Thoughts: "Why does it have to happen when we deeper and it counts more?!" "Why me? Why now?"

Here are the two hands in question:

4bet pot KK

set facing villian's cbet/3b and turn overshove

I'm trying to dissect where i can improve my mental processes here? Is it entitlement tilt that i'm feeling? Since the villain really blundered do i feel like the pot is meant to be mine? Does it just hurt more because i perceive there is more on the line? Both hands are a really good spot to pick up or chips or win a decent size pot, is that what's affecting me?

If villain had to shove a flush draw on the flop and it gets there on the river, I wouldn't have the same reaction. So do i simply learn to move my tolerance threshold for not realizing 90%+ equity (from 50%-80% per say) or is something else going on here? I'm wondering if it matters that villain was trying to bluff me? Have i created a built-in 'acceptable' level of bluffing equity that i'm 'allowing' villain to use against me? - i'm speculating here as i try to delve into what i may be thinking

Since, i did react poorly in these situations i'm hoping to improve my emotional control in these spots in the future. Any thoughts?
