What about A-K? That hand is also recommended for a raise in every position – but it’s not a made hand. A large pair like that is a huge favorite against even several opponents. This makes sense they’re both very strong starting hands, because they can actually win quite a few pots unimproved.
Any starting hands chart you’ll find will reinforce this: A-A is listed as a raising hand for all positions, and so is K-K. It doesn’t take a great deal of experience to know that pocket aces are the best starting hand in Texas Hold’em.
