Great video Jeremy. Unfortunate ending but you played great. I especially enjoyed the pressure you applied with your 3-bets, definitely something that's been lacking in my own game at these stages in the tournament.

KK hand @ 3:30. Flop is KJ2 and you check to a 19/13 villain. Your turn bet was 45% pot. It looked to me like a spot where you could size up to 65%~ given that perhaps all of villains continuing range has a pair and a draw. I know that's a bit of a nitpick but I'm curious about your thoughts. You did mention betting small as a river option and to me that seems best. You let him off the hook with his AJ/JTs combos when you check and QTs/AQ likely raise vs a river block sizing which also has the benefit of pot sticking him more than a xr would when he has those hands.

A7s hand at the end when shorty jams and big stacks flats was tough.

I ran it in ICMIZER if villain jams:

My first reaction was to shove here because he should be plenty capable to flat this spot wider than he "should" with a hand like 97s or something since it's a 5bb shove in the CO and SB has all the chips.

Fiddling around with ICMIZER some more, it's pretty much breakeven at best if he has any traps. If he mixes traps and some hands outside of his advised calling range and never folds to a shove it becomes worse than breakeven. It's a bizarre spot but I think the way you ranged it in the video was spot on.
