KK vs T9s is the "big pair against live cards" spot: KK wins 78.7%, T9s wins 20.9%, and 0.4% of boards chop. Even at a 3.8-to-1 deficit, T9s keeps about 20.9% because suited connectors attack three ways at once — pairing either card, completing a straight, or filling the flush.
Think in variance terms: 78.9% equity means KK loses this all-in nearly 21 times in 100, so even a "dominant" spot is a coin you'll see come up tails plenty. Getting it in as the 78.9% favorite is correct every time; the 21.1% that goes the other way is math, not a misplay.
With the overpair, bet big and bet now — T9s 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 20.9% equity is real but realized best in position with the chance to fold out the pair, not by stacking off blind.
