JJ vs 75s is the "big pair against live cards" spot: JJ wins 78.8%, 75s wins 20.8%, and 0.4% of boards chop. Even at a 3.8-to-1 deficit, 75s keeps about 20.8% because suited connectors attack three ways at once — pairing either card, completing a straight, or filling the flush.
Translate that into a decision and it's simple pot-odds math: counting split pots as half, JJ carries 79.0% equity and 75s 21.0%. Against a pot-sized shove you need about 33% to call and about 25% versus a half-pot bet — so 75s 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 75s 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 20.8% — the hand's value is in the pots you take away postflop, not in flipping all-in preflop.
