JJ vs KT is a lopsided race — only one of KT's cards is an overcard to the pair. JJ wins 70.2%, KT wins 29.4%, and 0.4% of boards chop. With roughly half the outs of a true two-overcard flip, KT is a clear 2.4-to-1 dog that usually needs to pair its live card (or find a sneaky straight/two-pair runout) to win.
Translate that into a decision and it's simple pot-odds math: counting split pots as half, JJ carries 70.4% equity and KT 29.6%. Against a pot-sized shove you need about 33% to call and about 25% versus a half-pot bet — so KT needs real fold equity, not just its raw share, to justify stacking off.
How you play JJ vs KT depends on which side you hold. With JJ you're not crushing, so keep the pot controllable and take the 70.2% edge to showdown when you can; with KT, your equity is enough to continue with initiative but thin enough that bloating the pot out of position is a trap.
