| Turn | 86% | 14% |
77 vs 66 is two made hands colliding before the flop, and the higher pair owns it: 77 wins 81.0%, 66 wins 17.7%, and 1.3% of boards chop — 4.6-to-1. 66 has only two clean outs — the case cards of its own rank — so it must flop or turn a set, or back into a straight or flush, to claim the 17.7% of pots it wins.
At a final table the raw 81.6% / 18.4% split is only half the story — ICM bends it. As the 18.4% underdog, 66 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.
As the bigger pair, 77, your whole job is to get the money in before a scare card — there's no fold here and slow-playing only lets 66 realize its set equity for free. As the smaller pair, the discipline is recognizing when stacks are deep enough that calling off 17.7% equity is a leak, even though folding pre feels impossible.
