I don't really see how it matters? At the moment you have the best hand with the jack high full house and the only way you can lose is if someone has J6+ or QQ+ and hit on the river. If we look at the hand just from basic stats you know it's very unlikely with 3 jacks being shown already he has the fourth, it's about a 2% chance he does so I think was can safely rule that one out. If we look at the pocket pairs next we know he needs to to hit a set so to get the better full house, but the
odds of that happening are also very low just by going on the fact that sets in general are pretty rare and top set is even more rare (about 1% getting QQ+ and drawing a set is 22:1 of hitting). Now if we take these stats and add
pot odds to this (I have no idea the exact stack sizes but the principle should get across) it is an almost 100% profitable play to call anything with this hand. If he has a jack and doesn't make it better on the river you lose nothing and might win a few antes depending on the level. If he has a 5 thinking you can't possible also have a flush, giving him 555JJ, you double up. If he has QQ+ and doesn't hit on the river you still win. If he does have one of the few
hands that beat you, then you get knocked out but taken the actual goal of poker in making smart educated decisions I would basically insta call that. Hope that helps!
