66 vs AK is the classic preflop race — a pocket pair against two overcards (connected overcards). The pair noses ahead: 66 wins 54.1%, AK wins 45.5%, and 0.4% of boards chop. The unpaired hand has six outs twice over (any Ace or King), and with its straight gappers live too the whole thing sits within a few points of a coin flip.
Think in variance terms: 54.3% equity means 66 loses this all-in nearly 46 times in 100, so even a "dominant" spot is a coin you'll see come up tails plenty. Getting it in as the 54.3% favorite is correct every time; the 45.7% that goes the other way is math, not a misplay.
In practice, 66 vs AK rewards aggression from the favorite and caution from the dog: 66 wants to realize its 54.1% edge by getting value and denying free cards, while AK should lean on fold equity and position rather than hoping to win the pot at showdown about 1 time in 2.
