Partner opens 1♥, and RHO bids 4♠.

What is the most sensible use for 4NT here? Minors, Key-Card, Natural?

This thread has some possibilities for this and related cases. In general I would expect most to use this as "2 places to play".

Thank you thank you thank you.

I'm still a little puzzled about the best use for 4NT in the above auction but the thread you linked to has a further link to another thread (the "bebop 20 hours of college math" thread) which

a) is one of the funniest things I've ever read, and
b) reveals just how many really really clever people there are who contribute to this forum.

Anyone reading this, do follow the links, you will really enjoy it.

a possible usage is also to play it as good-bad, to allow you
to differenitate between hand with / without SI and to generate
a forcing pass seq.

Espesially usefull, if the prempt could be wide ranging due to
the fact, that the partner of the preemptor is a passed hand.

With kind regards
