Holdem Odds for Pairs and High Cards Before the Flop
It's always nice to start with a pair in the hole (especially the high kind) because they can often win without any improvement whatsoever. By the same token, an opponent's hidden pair can also often sneak up and beat you.
Here's some odds charts that can give you a way to not only estimate your chances of catching pairs, but to also get a feel for the likelihood of pairs in your opponent's hands.
High Card Hands (Unpaired)
Whoever said that Holdem is a high card game was right. Much of the overall Holdem action involves two unpaired high cards like the typical hands illustrated above. These probability charts will give you some idea of what to expect to be dealt, and how many high card hands are likely to be out there against you.
