K being third doesn't seem to give us much information here, so I would immediately try out the answer choice that tells us the most. The only answer we really know much about is h, since h is before s, and putting hk together tells us about j. So I'd test h out first.
_ _ K H _ _
We know that s would be one of the last two, and we know that j cannot be 2 or. 5 as this would violate the first rule. However this would force j into either one or six, would violate violate the j rule, so this cannot happen.
