Molybdenum Forcing Pass System:
S ---- N
P --- 1♣ (opening, not yet GF)
1♥ --- 2♣ (15-18 any, specifically not GF but could be invitational with clubs)
2♥ --- 2NT (4+ hearts, invite with balanced hand)
3♦ --- 3♥ (5-5 in red suits or 5-4 with accepting invite, 3 hearts)
4♥ --- P (signoff)

My system is weird...

Oh, didn't notice that east will bid one spade. Then
S ---- N
P --- 1♣ (1♠) (explained above)
dbl (2♠)--- 3♣ (4+ hearts, 4+ clubs/ 8+ points)
3♦ --- 3♥ (5-4 in red suits or better and usually 13+, 3 hearts and 8-9 points)
4♥ --- P (signoff)

Unnamed Homebrew Diamond
This South hand is an absolute minimum, but the fact we've got 6-7 CPs makes it tempting to open 1♦. I'll give both auctions:
1♦-1♠ 16+, excluding GF / 8+ almost any
2♠-2N Single-suited ♣ OR short ♠ OR both reds / relay
3♦-3♥ Both reds, ♥ not longer / suit preference
4♣-4♥ 4,6 or (since we're playing ♥) 7 CPs / signoff

If South decides to open 1♥:
1♥-1♠ 10-15, 4+ ♥, possible longer minor / forcing enquiry (typically denies 4♥)
3♦-4♥ Maximum (could be a little worse), 5+♥, 4+♦, ♦ could be longer / To play

You are South and 2nd seat. Favorable vulnerability. Scoring is imps. Dealer passes. I think South's hand qualifies in most strong club systems for a 1C opening, but make your normal opening. If possible your RHO will overcall 1S. If possible your LHO will raise to 2S unless responder establishes a game force AND the 2S bid takes up no room. For example, if the auction goes P 1C P 1D* (1S) 2H he will pass.
