How high do the bounties have to be in relation to the buy-in of a MTT in order to make shoving blind every hand from the get-go until doubling up or busting +EV?

uh....

Your Q doesn't make any sense. Imagine a tournament with no "buy-in", just a KO bounty of $1. There is no prize pool for the tournament, so you just play for as long as you have chips and try to KO as many people as possible.

Why would it ever be +EV to blind shove allin from the get-go? You have to win an ai to get Villain's dollar, Villain's calling range crushes yours, and if you lose you lose your dollar plus a chance at more dollars.

You seem to be forgetting that, regardless of tourney structure, Hero's main goals are to be ahead of Villain's range when the effective stack is ai, and to maintain his stack so he can experience more +EV KO situations in the future.

I'm no expert in KO strategy but the way I play KOs is just to take more marginal aipf spots than I normally would. You may also consider applying this logic to post-flop play -- e.g., make slightly lighter calls against all-ins post (depending on situation) than you might in a regular MTT where bounties do not factor into EV calculations.

You are underestimating how much not having a prize pool, EF and BI distorts play. There some similarities to playing a cash game without blinds or antes. Important differences perhaps, but certainly weird. Instead of illuminating, such a scenario is little more than a digression and is at best confusing.

What are EF and BI?

Your post is unclear. I don't really know what you're talking about or what part of my statement you're responding to. You're saying the KO scenario I described would be like a cash game w/o blinds and antes? I'm not sure how that would be the case, as I didn't say the tournament structure I'm *proposing* wouldn't have blinds. Just that there wouldn't be a prize pool. You still have to play pots to not get blinded out.

"such a scenario" -- what scenario are you referring to? Your cash game example? The tourney structure I proposed? Something OP said?

i havent played many bounty tournies but id look at accumulating a cash prize bounty the same as i would as accumulating chips that u hope to to get a cash prize from.

if the buy in is $100 for 10k chips and the bounty is $25 ill view the possibility of busting an opponent as a pot with an extra 2.5k chips in the middle.

the few i have played were a fast structure with loose players making them pretty fun but imo pretty hard to be beaten or find an edge in

idk how shoving every hand would make any sense tho
if u shove any two from UTG 9 handed ur prob gonna get a caller and youll prob be behind. no bounty & no chips
