Partner might hold good ♥s; even with RFR, I'm choosing a forcing sequence that lets her bid them. So some route to 2N, opening or rebid, or reversing into ♦s, then 3N if I don't hear what I'd like.

One of my partners came up with: 1♥-2♠ = GF, balanced (no good 5cd suit) with 2-3 ♥ 1♥-2N = LR+ with ♠ stiff or J2NT-style balanced 4cd raise, 3♣ asks 1♥-3m = LR+ with m stiff 1♥-3♥ = 4cd LR (she doesn't like 1M-3M = preempt or mixed; YMMV) 1♥–3♠, 4m = void splinter.

Echoing what others have said: It is clear that the D did not do her job, which would've entailed finding out what the agreement was, what followups are mandated, who misbid, who is under obligation to stay asleep, etc. But without this information, I don't see how it is possible to determine whether 4♠ is taking advantage of UI or a permissible bid within those agreements. Might it not turn out that the ruling was correct, though for wrong reasons?

There have been a bunch of threads on 1D-2C GF auctions. I prefer 3N = stiff ♣, no 4cd major, long good ♦, limited 14-15. Same hand with 16+ bids 3♦. 1♦-2♣/2N = 12-14 or 18-19, denies 5♦, does not deny 4cd M but does show stoppers in both majors.

Exactly, and generalizable. After partner's slow signoff, if I hold 3 or 4, and don't know we are slammish from the rest of the auction, we don't understand any of our slam bidding techniques. Also, kudos to Thompson, above: There is a lot of hesitation in these auctions, especially in comp and especially if the partnership plays something requiring counting steps over keycard interference.

Some time ago I found a structure for Intervenor's strong hands – for those who have made game sitting over the WNT bidder – that allegedly was played at some point by Greco-Hampson:

2NT 1. Both Minors two-suited with Opening Values 2. Invitational Jump Shift in any suit 3m Strong Brozel, Hearts and the minor 3H Strong Brozel, H & S 3S Strong Brozel, Spades & a minor

Advancer just needs a fit and a dummy entry or two. We combine these calls with Multi-Landy; Advancer's 2N is an inquiry.

DW: In fact, when I looked into it, I found that most who use the 2N SI relay in XYZ only do it with 4M and big m fit–the 5M-4+m slammish hands take care of themselves with R's 3m rebid (provided 4cd support is enough for the p'ship). And yes, in the OP layout the limited rebid takes S from behind the wheel.

SB: Using the 2♦ GF instead of the 2N SI relay, N will not show the ♣ short unless S provokes a cue bid auction. Several possible auctions, e.g.

1♦-1♠/1N-2♦ (GF)/3♦ (deny 3cd♠, 4cd♥)-3♥/3N or 1♦-1♠/1N-2♦ (GF)/3♦-3♠/4♠ or 1♦-1♠/1N-2♦ (GF)/3♦-3♥/3N-4♦/5♦ or 1♦-1♠/1N-2♦ (GF)/2N-3♦/3♠-4♠ or 1♦-1♠/1N-2♦ (GF)/2N-3♦ (helps to have agreement to ‘untangle 3♦’)/3N or 1♦-1♠/1N-2♦ (GF)/2N-3N….

depending upon style and where the air conditioning vents are aimed.

Fair point, but yes and no, I think. The question is whether and how to get started. Systems take over after that. Your answer, rebidding ♦s naturally, commits to slam exploration, so IMHO that answers the question. I agree that the continuation questions could simply have said that, whether 1♠-2♣ or 1♣-1♠/2N.

Obviously, I meant this as an evaluation problem, and I confess that it is somewhat trivial. Rule of 20ers will knee-jerk open. Rule of 22ers can't quite make it unless deciding upon some compromise valuation of two stiff Qs. Obviously, much can go wrong when choosing to open these things, but it seems to me very clear that even after P-1♣/1♠-2N, we have to look at slam. In fact, perhaps more so than after 1♠-2♣, b/c in the first sequence it is East who ought to be able to see the slammish values, both Qs should be pulling their weight, while West will be driving the auction in the second sequence. But, I should say, with some confidence.

- after 1♠ - 3N

If partner bids 4♥ – I presume this is 5+-5+? –, how strong is she?

1♥-2♠ = GF, balanced (no good 5cd suit) with 2-3 ♥

1♥-2N = LR+ with ♠ stiff or J2NT-style balanced 4cd raise, 3♣ asks

1♥-3m = LR+ with m stiff

1♥-3♥ = 4cd LR (she doesn't like 1M-3M = preempt or mixed; YMMV)

1♥–3♠, 4m = void splinter.

Parallel for ♠, but 1♠-3♣ = ♣ stiff or J2NT

1♦ (1♠) 2♥ - (p)

2♠-(P)-3♥-(P)

4N

b/c 4N would be quant.
