I recently bought the 150$ course for PLO for which I think its extremely undervalued. Didn't go through much of it, but its very comprehensible and I plan on using this site even more. Props to Emty for it.
ANyway regarding the hand. I am just wondering what do you guys think about my river call. I was going back and forth with the villain (Horny Hob), and since he was really going for it and representing a set what do you guys think about the call. Was it mathematically sound? I mean 50k in the pot and I needed to put 10k more in to see if I am right or wrong. I am just curious about your thoughts. He tried to bluff me with blockers a few hands before this one and I showed him a bluff as well.
