spr of 1 i say go all in on the flop

With the pot being MW you are going to need more equity than usual to stack off on the flop. I believe you likely have around 30-35% equity against those really wide ranges, but stacking off and getting called I think isn't as good as the line you took because the limper who cold called is likely going to play pretty straight forward in that spot, so you get to see what he's going to do and if he folds, then the maniac likely will shove a pretty wide range there with probably combos like any clubs, any pair+straight draw, and likely any T+, so overall you are doing pretty well against that range especially blocking the ten. If you were HU I think you would just shove against the maniac as his range his very wide and you block combos that make up the top of his range.

Pretty sure with the T and SPR 1 vs wide ranges you just jam yourself. You dont want to give free cards and while you are not fist pumping when called protecting your share of the pot and netting a bit of FE is worth it.

Checking allows villain to make good decisions vs your specific hand especially. SPR of 1.5+ and things def get trickier.

I play live-shortstack plo, and based on the analysis I have made over the years on propokertools, and other things the rules is a follows(generally!). Spr 1 on a flush board HU u can stack off with just a pair all day long(usually overpair/top-pair) As soon as it gets over 3-way+ its MUCH less clear on what is EV+ and not.

To summerazy you might be making a SMALL mistake by JAMMING 1st in or you might NOT. If I remeber correctly it might even be more EV to stack off on boards where done straights exisist like 765r/ or 896r, then boards that are suited. Most likely is it because you have so less outs when one of villians is flushing.

Ofc it's more clear to stack on a T26cc board then perhaps T95cc in the same scenario. So in general 3+way plus u have 1 pair I think u can probably just fold and not leak. Because even IF you are right its damn close in general based on their stack off ranges.

In other spots it might be nice to have an image as the ''guy who stacks on ANY boards after 3-bet KK/AA, so in certain spots u get called MUCH lighter then they should. This is if you play against same people.

ANOTHER factor is HOW deeo are the 2 villians. It could be CLEARLY EV to jam yourself if ONE of them overjams and the one left will have a very hard time calling his re-push. In that case jamming becomes much clearer option.
