AA vs A2s is a card-removal spot: the pair holds one of the cards the unpaired hand most wants. AA wins 87.2%, A2s wins 11.5%, and 1.3% of boards chop. Blocking an out (and vice versa) pushes the favorite past a clean race — it's one of the most common all-in confrontations you'll actually face.
Think in variance terms: 87.9% equity means AA loses this all-in nearly 12 times in 100, so even a "dominant" spot is a coin you'll see come up tails plenty. Getting it in as the 87.9% favorite is correct every time; the 12.1% that goes the other way is math, not a misplay.
In practice, AA vs A2s rewards aggression from the favorite and caution from the dog: AA wants to realize its 87.2% edge by getting value and denying free cards, while A2s should lean on fold equity and position rather than hoping to win the pot at showdown about 1 time in 9.
