How KJ vs T8s unfolds by street

King-Jack (KJ) is still ahead on 73% of flops against T8s, and the lead survives to the turn on 68%. T8s takes the lead on the other 27% of flops. These figures come from full board enumeration, not a simulation.

KJ vs T8s is a four-live-card fight — no pair, no shared rank, just rank order and geometry. KJ wins 62.1%, T8s wins 37.3%, and 0.7% of boards chop. Whoever pairs first usually scoops, so the edge comes from KJ making the higher pair plus whatever straight and flush equity runs between the two hands.

Think in variance terms: 62.4% equity means KJ loses this all-in nearly 38 times in 100, so even a "dominant" spot is a coin you'll see come up tails plenty. Getting it in as the 62.4% favorite is correct every time; the 37.6% that goes the other way is math, not a misplay.

In practice, KJ vs T8s rewards aggression from the favorite and caution from the dog: KJ wants to realize its 62.1% edge by getting value and denying free cards, while T8s should lean on fold equity and position rather than hoping to win the pot at showdown about 1 time in 3.
