Anytime I see AA, KK, QQ, AKs or AKos as hole cards, warning lights flash. These top hole cards usually signal high bets and the potential to win or lose big. This is when my inner banker runs for the safety of the vault, yelling, "Yo! Caution if many players go all-in before you!" or "Yo! Don't go all in unless necessary!"
By training, I mentally read top hole cards backward to remind myself of their real value. For instance, AKos is just that - a high card with a high kicker. AKs has more value since it might run to a flush whereas AKos might pop-up as a straight. If neither develops, any pair could crush either. Other top holes come with difficulties, too. The problem with QQ is there might be a KK, and with a KK there might be an AA. Going all-in pre-flop, however tempting, might pose a
bankroll difficulty. Instead of going for the pie, maybe settle for a slice or two.
Approximate %s
AA or KK hole cards will win approximately 8300 times out of 10,000 hands played, or 83%. It also means they will lose 1700 times out of 10,000 hands played, or 17%. So, in the long run, AA or KK win. But, in the short run, they lose - maybe all day long! Aggressive playing calls for a bet, raise and re-raise pre-flop. Almost ditto for QQ. With a winning percentage of 79 and a losing percentage of 21, QQ calls for a bet, raise and call pre-flop. (Do the %age math.) If QQ flops dead, caution, especially if A, K or any pair hit the felt. AKs hole cards have a 65-67 win%, and AKos hole cards have a 63-64 win %. In both cases, bet pre-flop. However, if nothing flops for either, check both. If raised, fold both. Do not make the mistake of chasing a flush with AKs or a straight with AKos unless with a four-carded low-bet or check. Do not chase high pairs either.
**PS: Note that I am not saying do not go all-in with AA or KK... it's a valid choice, just not mine unless necessary!
