 almost all grammar materials say: the simple present tense tense is about something in general, not something happening at the moment of speaking. for example  suppose i'm at a party.  i can say: I'm enjoying the party. i am not supposed to say I enjoy the party. i understand that. but more often than not I  come across exceptions (at least i think so), for example the sentence i happen to know the answer.  here "happen" is used to talk about the situation right now (at the moment of speaking). it can't be in a general way , habitual or something.
 the how can i tell when the tense is used in the general way or specific way as right now( at the moment of speaking)?

You need to learn more - yes, the rule is correct, but that's not the only rule.

You also use present simple for statements of fact (I happen to know...) and stative verbs (I know the answer). We do not use a continuous form in either case.
