$10 PLO 6-max: Nut-straight, no improvers facing 2 All-Ins (Med SPR)

I flop the nut straight on a two-tone flop, without ways to improve and in the worst position. The SPR is 4 for the original shove and 5 for the reshove. I lead out for a bet, which might be too ambitious with such a "meh" hand and get shoved on by both other players.

SB checks, Hero bets 10.5 BB, CO raises to 40.4 BB and is all-in, SB raises to 54.1 BB and is all-in, Hero ?

My gut feeling is that this is just a fold against two people. Against a single player, I think this might be a call (maybe not), but against both I am probably tied in at least one spot and looking at fading a bunch of cards to retain any equity in the pot.

Should I have just checked from up front with the bare nut-straight three way? If I do, is it a check-call for at least one street and maybe shove safe turns. Or, still a check fold?

you'll have at least 25% equity here.. you're good. Esp. at these stakes. maybe if you hadn't potted and there were 2all ins in front of you, but this is a call for sure.

You've already put in 10 bb's, and their stacks are shorter. As nkat says, you're good. Sigh and throw your $ in.

Leading is fine. Being freerolled at these stakes & stack sizes isn't a big issue.

"Sigh and throw your $ in."

I do that in plo a lot lol!!

I have to call 43.6xbb more, the pot will be 159.1xbb after I call. That means I need around 27.4% equity to call here. When we take rake into account (88xbb in this case), the pot will be 150.3xbb, and I will still be risking 43.6xbb more, so I need about 29% to break even,

So, yeah, if I have 25% equity, then I probably have to call. Because we do have to account for the chance that someone is spazzing out. Against the same straight, and an over-pair with a flush draw, I have 26.6%. So, enough to call.

The thing is, there are a lot of spots I can think of where I am just about getting the right odds to stick the rest in. And, there are a lot where I am just not. Say someone has A-T-9-x, and the other person has Q-J-x-xdd. Those aren't unreasonable hands, but those have me in nasty shape.

* at9 32.17%
* qj:dd 49.91%

There are a lot of combinations they can hold that put me in the 15%-20% range. Some even worse (set+fd against K-T-9-x has me at 11%). I found a few combinations that put me in the 20-25% range, but very few put me higher than that. I know that worrying about being up against two perfect hands (QQ:dd and A-K-T-9 [9%]) is just being paranoid at these stack sizes and stakes. But, I feel like it's too optimistic to think neither of them has the straight and they're spazzing out with something that gives me 30%+ equity.

I guess it's putting them on reasonable ranges that I'm struggling with most. I mean, I did end up calling and I know exactly what they did end up having, but that only gives me a clue as to their range.

What do you think is a reasonable bottom end for someone to be shoving here? What about reshoving, where you know that you are going to showdown and have no fold-equity? The second player should have stronger equity than the original shover, I would think.

Edit: If, at some point, you feel it would be valuable to know what they actually did have. I can provide it. But, I feel like it would just distract from the discussion.
