Molybdenum Forcing Pass System:

S ---- N
P --- 1♣ (opening, 0-bad 12)
2♣ --- 2NT (club void and 16- bad 20/21, invite or better in a suit or GF in NT)
3♣ --- 3♥ (asks for more information, invite or better in hearts)
3♠ --- 3NT (either a spade cue or 3 or fewer hearts, asks for clarification)
4♦ --- 5♥ (agrees hearts, extras)
5NT --- 6♣ (GSF, king or ace of hearts without queen)
6♥ --- P (signoff)

The sequence is not finalized, I'm still working on this part, as my slam biddings after opener shows a void are still unrefined.

with interference it goes:

S ---- N
P --- 1♣ (1♠) (see above)
2♠ --- 3♠ (strong hand with hearts and a minor, near maximum with heart support)
5NT --- 6♣ (GSF, K or A without queen)
6♥ --- P
Easier with interference.

You also need to add a 1♠ overcall by East and a 2♠ raise by West. I am guessing you will not have 2♣ available as a void-showing bid over that.

As an aside, if North does only have an invite in hearts, how do you stop short of game?

...that's why I'm working on it
If I make the 2NT --> 3♥ call GF then I still don't have an invitational. I suppose I could make 3♥ over 2♣ the invite, but I won't have an invitational bid over 2♠ if that's also void-showing.

Here's a possible solution:-

2♣ = diamond void
... - 2♦ = GF relay
... - 2M = to play
... - 2N = invite in any suit (3♣ to decline a club invite (Paradox))
... - 3♣/3M = nat GF
... - 3♦ = pick a major
2♦ = heart void
... - 2♥ = GF relay
... - 2♠ = to play
... - 2N = puppet to 3♣, minor sign off or invite in spades
... - 3m = nat invite
... - 3♥ = GF in unknown minor
... - 3♠ = nat GF
2♥ = spade void
... - 2♠ = GF relay
... - 2N = puppet to 3♣, for sign off in any suit
... - 3m/3♥ = nat invite
... - 3♠ = GF in unknown minor
2♠ = club void
... - 2N = GF relay
... - 3♣ = puppet to 3♦, for sign off in any suit
... - 3♦/3M = nat invite

If you do not like the idea of a GF relay then you can rearrange to cover the different hand types more naturally, for example

2♠ = club void
... - 2N = puppet to 3♣, for invite in any suit
... - 3♣ = puppet to 3♦, for sign off in any suit
... - 3♦/3M = nat GF

As long as you make the 2♠ "rebid" show a club void, rather than 2♣, you have the necessary space.

quoting a long post is not a desirable thing in forums.

That looks very interesting and probably will fix my problem. Thanks very much.

You are most welcome.

What do you mean by "50-50 at best"? It is usually not a good idea to bid a slam that is at best a 50% chance.

Yes, an error, 50-50 at worst. I try not to bid slams that are only 50-50, trust the system.
