I do not like both of these cards !!! it is very difficult to choose because the chances of winning are equally bad, but still I play with such cards from late position !!!
I prefer lower ranked suited-connectors such as 87s and even 1-gappers like 75s because not only can they make straights and two pairs, but your more savvy opponents may become wary of your postflop play when the board is full of small cards. Furthermore, these kinds of hands are great in the early stages of MTTs to bust out weak players who are too committed with their weak hands or overpair.
J10 s is my very fav hand. I get more excited that AA. (There is something wrong with me) I have called an all in with it at times (its THAT good to me)..LOL bad christy bad christy!
They haven't been playing well recently, mostly because the only major tourny I've won is from going big on Q-10 three times in a row with them hitting hard each time. Otherwise it's probably dumb.
I prefer small pairs, something like 55, 77 and so on. If you catch the flop, this hand can be very dangerious and hard to read for your opponents.
Also i like suited connectors, something like 910 suited. This hand can also be very good.
K8s is oddly one of my weird hands that iv'e had success with.
I don't really like either hand in a larger scope of things, but K8s for me is the clear choice.
because you obviously have lots of odds, plus a royal couple is a royal couple, and their designs are not bad either, although that depends on the deck
I think it depends on the game you are playing too. If I was deep in a tournament and had a small stack with big blinds. I may want to have a king instead of suited connected.
But if I was playing in a cash game, I would prefer to play smaller suited connectors.
I prefer the hand AA because i can go all in with it or make a big raise.
And if my opponents calls i'm very pretty confident that i will win.
I prefer this hand because it's the best hand in poker.
If i had to choose between those 2 hands , i'd choose K8, because it's suited. AA never lucky cards in my hands. Seems like KQh are best hand for me, because i always get lucky with this hand on the flop.
