(ETA, in case it wasn't clear before - 1♠'s minimum value is a king stronger than normal - it's unlimited upwards. So in Fantunes terms, on HCP he's a sub-minimum)
Poll 1:
So matchpoints. We play a form of Gazz, so with the same shape but slightly more strength/solidarity, N would have rebid 3H (eg on AKJxx KQJTx xx x - it's nominally '16-18' , but, while we're still calibrating, it seems like most 5-5s with most values in the long suits should upgrade frequently).
Forgot to alert it in the description, but since we play Gazz, N is also capped at 17 points.
Should N or S be more optimistic, or are we just missing game along with the rest of the room?
Poll 2:
We might also have had a very different auction, if N hadn't upgraded initially:
W can open 2N, showing nominally 5+ spades + (5+ hearts or 5+ clubs) and 10-13 points (that is, the same playing strength as a normal Fantunes 2-bid), so again, upgrading into and out of the range is common). If he does so, S bids 3♣: pass or pull-to-3♦, and N with hearts does the latter (perforce, except on highly distributional hands)
Should N have opened this, or do you agree with his upgrade? Either way, supposing he did, is S now worth a punt at 4H (given that the opps know relatively little about his hand)?
On both poll questions, do your decisions change at IMPs?
