1/3 tulalip

Hero sb: 25 white male, stack 300

Villain hj: 50 white male, down syndrome. Went allin pre utg with k3o, got called in two spots in lost. Went allin again with KJo, flopped two pair and took the pot. Lost another allin with KQo. Stack 200ish

The hand:

3 limps, villain goes allin, hero wakes up with XX in sb. What is heros calling range?

ATo+, A8s+, KJo+, KTs+, 66+ imo. Could knock that down a bit if you are properly rolled, and have ready access to rebuying cash. Then I prob call with all my PPs.

Is this guy actually ******ed? I'm assuming he's not, but I've played against some literal ******s so I have to ask.

has he shoved every hand consecutively? would appear not since you say his holdings improved with each shove.

are any of the 3 limps behind him likely trapping with big hands or are they just your typical weak limp/folding types at 1/3?

It wasn't consecutive hands, but it was maybe 1/4-1/3 of hands he was going allin pre. The limpers may be trapping, this is also something that I have no way to know before I decide whether to make my call.

One of the limpers is a nitty old man, probably will fold.
One of the limpers is a guy who got stacked by villain in the KJ hand, $150ish. He may or may not go all in.
One of the limpers is a guy with a $50ish stack, he may or may not go all in as well.

However, obviously I cannot know their intentions until after I make my decision in the SB.

Here is the problem with this situation... It really depends. It for sure depends on your position. You range is going to change in each position. It's going to depend on the action before the all in. Last, it's going to depend on YOU. If you want a precise mathematical range then download poker stove or poker cruncher and do the work yourself. The thing is not too many people in LLSNL feel comfortable enough calling with a wide range and facing the variance. We cannot tell you what you should call with. We don't know what your bankroll looks like, what your emotional state is and how you will react if you lose, etc. Only you can answer that question.
