TT vs A4s is a lopsided race — only one of A4s's cards is an overcard to the pair. TT wins 66.8%, A4s wins 32.8%, and 0.4% of boards chop. With roughly half the outs of a true two-overcard flip, A4s is a clear 2.0-to-1 dog that usually needs to pair its live card (or find a sneaky straight/two-pair runout) to win.
Think in variance terms: 67.0% equity means TT loses this all-in nearly 33 times in 100, so even a "dominant" spot is a coin you'll see come up tails plenty. Getting it in as the 67.0% favorite is correct every time; the 33.0% that goes the other way is math, not a misplay.
In practice, TT vs A4s rewards aggression from the favorite and caution from the dog: TT wants to realize its 66.8% edge by getting value and denying free cards, while A4s should lean on fold equity and position rather than hoping to win the pot at showdown about 1 time in 3.
