JJ vs 65s is the "big pair against live cards" spot: JJ wins 77.7%, 65s wins 21.9%, and 0.4% of boards chop. 65s is the kind of hand that hates folding — its flush and straight draws mean it gets there roughly 21.9% of the time, far more often than a dominated big-card hand could.
Think in variance terms: 77.9% equity means JJ loses this all-in nearly 22 times in 100, so even a "dominant" spot is a coin you'll see come up tails plenty. Getting it in as the 77.9% favorite is correct every time; the 22.1% that goes the other way is math, not a misplay.
With the overpair, bet big and bet now — 65s has the draws to make your life miserable on later streets, so charging it the maximum before the flush and straight cards arrive is the entire plan. From the connectors' side, the 21.9% equity is real but realized best in position with the chance to fold out the pair, not by stacking off blind.
