Put an overpair in against suited connectors and JJ vs T8s is the result: JJ wins 81.6%, T8s wins 18.0%, and 0.4% of boards chop, a 4.5-to-1 edge. T8s is the kind of hand that hates folding — its flush and straight draws mean it gets there roughly 18.0% of the time, far more often than a dominated big-card hand could.
Translate that into a decision and it's simple pot-odds math: counting split pots as half, JJ carries 81.8% equity and T8s 18.2%. Against a pot-sized shove you need about 33% to call and about 25% versus a half-pot bet — so T8s needs real fold equity, not just its raw share, to justify stacking off.
JJ should play this fast and deny equity: every free card helps T8s more than it helps you. If you're the one with the suited connectors, lean on implied odds and fold equity rather than the raw 18.0% — the hand's value is in the pots you take away postflop, not in flipping all-in preflop.
