Share a card and you get a kicker problem — that's KJ vs K7s: KJ wins 65.3%, K7s wins 27.4%, and 7.3% of boards chop. Note the chunky 7.3% 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 69.0% / 31.0% split is only half the story — ICM bends it. As the 31.0% underdog, K7s 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 KJ vs K7s is kicker discipline: K7s is the hand that quietly costs people stacks because it's too strong to fold and too dominated to win. If you hold KJ, 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.
