JJ vs 33 is two made hands colliding before the flop, and the higher pair owns it: JJ wins 81.2%, 33 wins 18.3%, and 0.5% of boards chop — 4.4-to-1. The lower pair, 33, is drawing to the two cards left in the deck that make it a set; miss those and only a runner-runner straight or flush saves it, which is why it gets there just 1 time in 5.

At a final table the raw 81.4% / 18.6% split is only half the story — ICM bends it. As the 18.6% underdog, 33 pays an extra survival premium, so the chip-EV "close enough" call can be a clear ICM fold. The pure equity sets the floor; the payout ladder sets the real price.

As the bigger pair, JJ, your whole job is to get the money in before a scare card — there's no fold here and slow-playing only lets 33 realize its set equity for free. As the smaller pair, the discipline is recognizing when stacks are deep enough that calling off 18.3% equity is a leak, even though folding pre feels impossible.
