Why isn't true belief enough for knowledge? Because that wouldn't rule out lucky guesses. True beliefs have to be obtained in the right way. What is the right way? Any way that gives true beliefs. But guessing does give true beliefs sometimes. So it has to be better than 50%. But that includes 51% which is almost as bad as chance. Is that knowledge? At what point does it tip the scale and become knowledge? Why is it that whatever you say will seem arbitrary? If there is no clear line then why hold to the distinction that there is even such a thing as knowledge rather than various degrees of probably true beliefs?
Though the line is not clear, (and particularly, it is not clear concerning the acquisition of justifiction, that is, at what point in time in the "knowing process" is one considered justified), it doesn't make much sense to me to consider lucky true beliefs, knowledge. This is because if we were to consider lucky true beliefs knowledge, we would be dismissing reason entirely; an educated guess would be no different than a lucky guess, and an educated person in X field would have the same understanding as an uneducated person who speaks about X field. If we deny reason in this matter, we are denying that some people are more knowledgable at certain things than others, and we are denying that the learning process is valuable.
Even if you find justification problematic, I think most reasonable people will admit that not every belief is the same. It is obviously clear to me that sometimes people believe things for bad reasons, while sometimes people believe things for good reasons. If we say there is no connector piece between truth and belief, we are essentially saying logic and reason have no bearing on why we should hold beliefs, and that, I think, would be being unreasonable.
