Share a card and you get a kicker problem — that's JT vs J9s: JT wins 63.0%, J9s wins 26.8%, and 10.3% of boards chop. Note the chunky 10.3% chop rate — it surfaces whenever the shared rank plays and the kickers don't. Spots like this are where stacks quietly disappear: the dominated hand can't fold pre and can't outrun the kicker post.
At a final table the raw 68.1% / 31.9% split is only half the story — ICM bends it. As the 31.9% underdog, J9s pays an extra survival premium, so the chip-EV "close enough" call can be a clear ICM fold. The pure equity sets the floor; the payout ladder sets the real price.
The lesson of JT vs J9s is kicker discipline: J9s is the hand that quietly costs people stacks because it's too strong to fold and too dominated to win. If you hold JT, get value while you're ahead; if you hold the dominated side, this is the exact spot to find a preflop fold against a tight range.
