The question you opened
Pocket twos against ace king
Two players are all in before the flop: a pair of twos against ace king of different suits.
Which hand wins more often?
The pair of twos
The twos are already a pair, and ace king has to pair up to pass them. Over every board the twos take it about 52 times in 100.
The twos are the favourite, by roughly 52 to 48. The reason is that the pair is already made and ace king is not. If neither hand improves, the twos win. Ace king needs to pair its ace or its king, and there are six such cards left in the deck. Over five community cards it catches at least one of them a bit less than half the time, and even then the twos can make a set, two pair, or better.
The gap is smaller than a beginner expects and larger than a beginner expects, in different directions. Card for card, ace king looks enormously stronger. In terms of showdown equity, it is the underdog. Yet the underdog is only a coin flip underdog, which is why the matchup is called a race rather than a beating.
Suits move the number. Against ace king suited the pair drops to roughly even, because the flush adds outs that do not depend on pairing. Bigger pairs win more: against ace king, a pair of tens is a similar 55 to 45, and a pair of queens is about 57 to 43, since queens block nothing but survive more boards.
The lesson is not that small pairs are strong hands. Raw showdown equity is only half the story, and ace king is far easier to play after the flop. When ace king misses, its owner folds cheaply. When a pair of twos misses a set, its owner is stuck holding the worst hand that thinks it is ahead.
Professionals prefer ace king for exactly this reason, and the preference has nothing to do with the number in this card. What the card is really about is the difference between how strong a hand looks and how often it wins. Those two questions have separate answers, and only one of them can be counted.
