| Turn | 90% | 10% |
KK vs JT is about as good as a non-cooler gets for the pair: both of JT's cards are undercards, so no single card flips the lead. KK wins 83.1%, JT wins 16.6%, and 0.4% of boards chop. The underdog has to pair twice, make a straight or flush, or otherwise back in — which is why pairs stack undercards so reliably at a 5.0-to-1 clip.
Think in variance terms: 83.2% equity means KK loses this all-in nearly 17 times in 100, so even a "dominant" spot is a coin you'll see come up tails plenty. Getting it in as the 83.2% favorite is correct every time; the 16.8% that goes the other way is math, not a misplay.
In practice, KK vs JT rewards aggression from the favorite and caution from the dog: KK wants to realize its 83.1% edge by getting value and denying free cards, while JT should lean on fold equity and position rather than hoping to win the pot at showdown about 1 time in 6.
KK vs JT FAQ

Does the KK vs JT probability change all-in preflop?
No. Once both hands are all-in preflop the odds are set by the cards alone — position, stack size and who bet first change nothing. The only thing that moves the number is suits: KK's equity runs from 79.7% to 85.0% depending on suitedness and which suits the two hands share, which is why different sites quote slightly different figures. It does change once board cards are dealt (KK leads on 95% of flops) and in multiway pots, where every extra caller takes equity from both hands.
Is KK vs JT a good spot to get all-in?
For KK, yes — a 83.2% favorite should happily commit, especially with fold equity. For JT at 16.8%, it depends on the price: enough to continue with initiative, but thin enough that stacking off out of position is usually a leak.
Does KK hold up against JT after the flop?
KK is still ahead on 95% of flops and stays ahead through the turn on 90% of boards; JT takes the lead on the other 5% of flops. These are exact figures from full board enumeration.
