FTOPS Event 2: $240 PLO8 Knockout

Edit: Yeah, I’m an idiot. It was late when I posted this, and I did in fact calculate my pre-flop equity rather than my flop equity. I’m actually a 2:1 dog here, which is more what I expected. Thanks to qanda201 for pointing it out in the comments. I thought it seemed too good to be true.

Shows what I know about this game. I was embarassed to even post this because I felt like I played this bad and got my money in bad, but turns out I’m a pretty substantial favorite:

My reasoning at the time was that he was either on a draw, in which case I had some of his outs and my Kings were good, or that most of my draws were live if he did have a made hand. Hard to say how I’d perform against his full range here, but I guess I get to write this one off to a bad beat!
