Here is the thing with junk hands. Any unmade hand is junk hand. AK is a junk hand preflop because it is an unmade hand just like 56s. The only advantage that it has over 56s is the Ace high. One good tip I could give you to play junk hands is take the lead in the hand when you play it and try to play it in late position. By raising preflop with them and putting out a continuation bet on the flop no matter what you hit (or not hit) give you a very good chance of winning with the hand.

By the way, by experience I try to stay away from 8T because alot of the times when when you do hit your str8 8-Q someone else has a better one because the str8 deals into the face cards and alot of people play theses cards. I try to stay in the 9 high str8s and so on.
tell me what you think.
