The exit hand here wasn't the key hand, so I'm including the key hand just prior to the KO.  I pick up pocket tens and get a min-raise from Roland in front of me.  I decide to make my 3-bet sizing so that I have a very easy decision on the flop as I intentionally create an SPR of 1.

I then get a shove and with it being only 5BB and having an A, I'm ahead of his entire range and should be calling a button shove with about 82% of hands and Ax is well within this range.  Unfortunately, he's at the very top of his range, so I need to hit my 3-outer to knock him out.
