All three can still be beaten so the answer iiiiiiiiss……….cautiously! Cautiously with all...….accept the AA's. Now, I know what your gonna say and believe me I've gotten all kinds of flack and heat for playing AA's this way. People screaming at me about, "oh it's a waste!" "You're giving up so much value." "Your wrong!"...…..but I don't care! ALL-IN PREFLOP with AA's okay!
I don't care! it's served me right in the past and it still does!
Now...……...when it comes to KKs, QQ's I play cautiously. Raise double the pot or call their raise and if I flop a set, and I don't see evidence of a straight or a flush then I build value with more bets; quarter or half the pot so as not to scare the villain. However, if I do see evidence of a possible straight or a flush; say if there's two of the same suit on the table and he's still calling my bets then I'll jam to make sure he doesn't catch his fish. Catch my drift? Most importantly, I look at his actions and how quickly he's making them to see what it tells me about what he might have. Good Luck!
