So to give some of my thoughts, I was a bit tilted at this point and just did a reckless all in. Another thing that is different about this PKO is that the starting stack is 10k in chips, compared to the 3k or 5k that I'm normally playing with. I didn't make that shift in thinking there. People may be doing the isolation 3bet all in there, but they are doing it with stacks of say 30BBs, and not 80.

I think the right play would have been an iso raise of 8BBs? Even then someone could just shove over the top of me.

I could call the 2BB all in and then wait to see what the rest of the table does? Once again, they could just consider it dead money and push me off.

I can see this is a blunder in that I risked too much to win a $5 bounty, with too many players left to act.

I'm wondering if there is anything else I need to think of or pay attention to in this situation besides 1) five players left to act and 2) having a deep stack? Or are those two factors essentially the only things I need to think about? Should I have been thinking about the future bounties to be won by forgoing the chance to target this one?

I have seen that the early isolation shove does work, but maybe that is more appropriate when stack sizes are shorter and it is later in the tournament where bounties are bigger. Where I'm risking less BBs, and the reward of the bounty is larger.

I am open to hearing any and all reasons why this play is bad. I just want to be able to pay attention to any details that I may have been missing when I maybe quickly and impulsively made this isolation all in jam.

Also I noticed that many stacks in bounty tournaments really get down to short stacks of like 8-10BBs before people are putting their chips all in. Is there any reason why stacks are shorter in PKO tournaments compared to regular MTT tournaments without bounties?
