Is 2♠ game-forcing? an Acol 2? something else? Did you also consider the option I chose (in almost the same spot) of North bidding clubs over 2♠? That keeps 3NT in the picture at the cost of not necessarily showing both suits. It is just that the difference between our contracts looks to me less about system as about judgement and decisions. That makes it more difficult to straube to evaluate. Which route do the others prefer?

The hand is too strong to be in the 18-21 category so

1C--1S (str, No M w or GF)
2D--2S (almost GF any shape, GF values 2-5 pts)
3S--3NT (showing 6 decent spades, soff
all pass.

Molybdenum pass system:
P - 1♣ (1♥) (opening, forced bid, overcall)
3♠ - 4♠ (South has 4 losers in spades and north has no heart stopper so they are pretty much forced to bid like this after the overcall)

Unnamed Homebrew Diamond:
we do have a "spades or both minors" preempt available, but I doubt either of us would open it second in at red on this... heap. So, S opens 1♦:

1♦-1♥ 16+, excluding GF / 0-7, no 6-card suit to an honour
2♠-?? 2♠ here is "almost-GF, single-suited" - much like an Acol 2, but definitely NF. N may pass here, or may try 3♦, in which case:
-3♦ showing a suit
5♦-end Anything else is NF, and when N shows diamonds with spade shortage this hand is worth a bid.

To be honest, I think 5♦ is resulting and we're more likely to subside in 2♠. It is possible that S decides his hand is worth a GF, though 4 losers is a bit much. In that case the auction runs:
3♥-3♠ Spades, weak or GF / transfer completion
4♣-4♠ 8 or 10 CPs / I don't care, we're not playing slam

Pass 2000
(North's initial pass means 0-7 or 17+ and is forcing)
1C-1D; (0-7 / 17+ -- 0-7)
(1H)

Our agreements after disturbed bidding haven't been discussed very much, except "strong hand must act, weak hand may not act on its own". I would probably bid like this:

2S - 3D; (2S should show extras and a good suit)
3S - 4C; (I don't really like the 3S bid, but 3H should probably be asking for stoppers)
4D - 5D;

It is possible to just bid 4S by south too (after 4C), which would then be the final contract. I guess this is more of a judgement thing than a system thing, in our case.
