AK vs 72o is a four-live-card fight — no pair, no shared rank, just rank order and geometry. AK wins 67.7%, 72o wins 31.8%, and 0.5% of boards chop. Whoever pairs first usually scoops, so the edge comes from AK making the higher pair plus whatever straight and flush equity runs between the two hands. You'll hear this matchup argued about constantly — the enumerator settles it for good.
Think in variance terms: 68.0% equity means AK loses this all-in nearly 32 times in 100, so even a "dominant" spot is a coin you'll see come up tails plenty. Getting it in as the 68.0% favorite is correct every time; the 32.0% that goes the other way is math, not a misplay.
In practice, AK vs 72o rewards aggression from the favorite and caution from the dog: AK wants to realize its 67.7% edge by getting value and denying free cards, while 72o should lean on fold equity and position rather than hoping to win the pot at showdown about 1 time in 3.
