When a pair meets two bigger cards you get a flip, and 77 vs KJ is exactly that: 77 wins 53.0%, KJ wins 46.6%, and 0.4% of boards chop. The overcards lean on six live outs — either King or Jack pairs to take the lead — which is why the unpaired side converts about 46.6%, the math behind every "I have to gamble" all-in in a tournament.

Translate that into a decision and it's simple pot-odds math: counting split pots as half, 77 carries 53.2% equity and KJ 46.8%. Against a pot-sized shove you need about 33% to call and about 25% versus a half-pot bet — so KJ is comfortably priced in to get it all-in here.

How you play 77 vs KJ depends on which side you hold. With 77 you're not crushing, so keep the pot controllable and take the 53.0% edge to showdown when you can; with KJ, your equity is enough to continue with initiative but thin enough that bloating the pot out of position is a trap.
