Why the odds look like this: overpair vs underpair
Both players hold a pocket pair, but TT can only win by improving: it needs to make a set, or hit a straight or flush that AA doesn't share. That is why a bigger pair is roughly a 4-to-1 favorite against a smaller one. When TT wins, it is most often with three of a kind (45% of its wins) or a full house (30% of its wins).
How to play AA vs TT
Getting all-in preflop with AA against TT is a big win in expectation. If you hold TT, you can't avoid this cooler entirely, but be cautious about 4-betting or calling a shove from a very tight player whose range is mostly bigger pairs.

Use these numbers at the table
Preflop equity tells you how often a hand wins if all the money goes in before the flop. To decide whether a call is profitable, compare your equity with the pot odds you are getting: use the pot odds calculator. In tournaments, short stacks decide with shove-or-fold ranges, so see the push/fold chart. To test any other hands or a specific board, use the poker odds calculator.
Do suits matter?
Yes, a little. Suited hands make flushes more often, and when two hands share a suit they block each other's flushes. That is why the same two hands can differ by one or two percentage points depending on suits. The figures above are exact for the example cards shown.
How we calculated these odds
We dealt out every possible five-card board (1,712,304 of them) for the example hands and counted wins, losses and ties. There is no sampling error: the numbers are exact for those cards.
