Hi,
#1 did stayman promise at least inv. values?
I seems so, otherwise 3H seems problematic.
#2 Assuming 3H showed 4 hearts, max. values, i.e. accepting the invite,
North can bid 4S, which is a splinter, if you want it, you can agree
to play 4S as Exclusion, ... but splinter work fine as well.
I dont play Exclusion in my reg. partnership, and we dont miss it heavily.
In the end 4S showing a void is only really needed, if you want to go
looking for a Grand Slam.
North has 16HCP out side spades, if they are not complete lunatics,
partner will have at most 4-5 points in spades, i.e. he will have 8-9
HCP out side spades, i.e. N/S will have 24/25 of the relevant points
between them.
The 30 point deck tehory tells you, you want to be in slam.

=> 6H.
If you happen to play strong NT, the same argument will make a 7H bid
odds on, although if you cant ask p, if he happens to have the Ace of
hearts, settling for 6H would still be reasonable.
#3 Regarding the meaning
If 2C showes inv. values, pass should be forcing, the 2C forced the partner
ship to play at least 2NT, so passing 2S out should not be an option.
Givem the hint, that this is B/I, I am not going to deep into Forcing Pass,
just that X is penalty, Pass no clear direction, asking partner, if he thinks
going for blood to be reasonable, 2NT would show a reasonable stopper, but no
interest in going for blood - for what ever reason.
With kind regards
Marlowe
