Difference???

Hello,I´m an intermediate student in English and I would like to know if anybody can explain me the difference between a sentence in the present simple with always ( which is a habit, as fas as I know), and a sentence in the present continuous with always as well ( which I reckon it is a repeated situation, as I´ve been taught).

After all the examples I´ve seen, I´ve deduced the difference is that the present simple is normally accompanied by a frequency (I mean, every two hours or every day) and the present continuous is not, although it can br accompanied by "all the time". Is this correct?

He always knows the right answer.
*He is always knowing the right answer.  (Impossible with certain stative verbs.)
?He knows the right answer all the time.
??*He knows the right answer every day.

*He always reads.   (Impossible with certain activities.)
He reads all the time.
He reads every day.

He is always reading.
?He is reading all the time.
He is reading every day.

He always reads cheap paperback novels.
He reads cheap paperback novels all the time.
He reads cheap paperback novels every day.
He is always reading cheap paperback novels.
He is reading cheap paperback novels all the time.
He is reading cheap paperback novels every day.

He always wins.
?He wins all the time.
He wins every day.
He is always winning.
?He is winning all the time.
?He is winning every day.

The exact words seem to make a big difference.  I'm not sure there's an explanation that covers all the cases.

Dear Mr Paco, thank you for your reply.

With your reply, I have understood that the stative verbs cannot be used in the present continuous even though they have got a continuous meaning, as in this example: He always believes me even if I deceive him from times to times. But in the dynamic verbs, which is my main concern, can be used either in the present simple, when it is accompanied by a time (e.g.: He always washes his teeth on Saturday mornings) or in the present continuous when it is a repeated situation which is only accompanied by always or all the time (e.g.: He´s all the time raising his hand, it seems he knows everything  or You´re always washing your teeth).

Is that what you are trying to explain to me? If it is, you needn´t post a reply, simply thank you. If not, it would be grateful if you could post a reply giving me your opinions as well as some examples.   

Thank you very much, Anonymons.

Well, I think, there is a little bit difference between "He always reads cheap paperback novels," and "He is always reading cheap paperback novels".

First sentence indicates his hibitual action. He never reads expensive novels. He reads only cheap paperback novels.

Second sentence indicates annoying or irritating. ( I told him not to read cheap paperback novels several times, and he never listens to me ), he is always reading cheap paperback novels.

See more examples :

He always reads a book in class. ( He never plays or talks or does anything except reads a book in class.) His habbit is reading a book.

Don't ask Michael to play or to talk, I don't want to talk with him anymore because he is always reading a book in class.

-He always reads cheap paperback novels. -He´s always reading cheap paperback novels. -He always wins. -He´s always winning.

The simple tense is emotionally remote, I'd say.  It seems only to state a fact.
The continuous tense adds a sense of immediacy.  It gives the impression that the speaker may have personally observed or been involved with the situation being reported -- more so than its simple tense counterpart.

1 (They say that) he always reads cheap paperback novels when he's bored.
2 He always wins because he is the best player.

3 He's always reading cheap paperback novels every time I see him.
4 (I've noticed that) he's always winning prizes.  He certainly is lucky.

By the way, you would not say 1 as "They say that he is always reading cheap paperback novels when he's bored".  And you would not say 3 as "He always reads cheap paperback novels every time I see him".
The ones with "wins"/"is winning" are slightly more interchangeable.  I cannot explain why.
