My reasoning at the table was:
Universe 2:
without the alert, I know that opps have strength but not a fit. The opps likely have the balance of the points and RHO has values in my spade suit. But I have 6-5 distribution and lots of playing strength. I am surprised that some are choosing to pass. Bidding 3
♣ seems entirely obvious to me - even at the vulnerability.
Universe 1:
At the table, there was an (incorrect) alert of the 2NT bid. Now the opponents have advertised a heart fit. There seems to be even more reason to bid, but the problem with bidding the shape is that LHO will have an easy 3
♥ bid or 3
♦ game try over 3
♣. I chose instead to repeat my spades and rebid 3
♠ (4
♣, as suggested by Gordon was also considered).
Was this a reasonable tactical choice?
The full hand was:
The director rolled the contract back to 3
♠=, based on my argument that without the incorrect alert I would have bid the normal 3
♣ and we would have stopped in 3
♠. My thoughts are:
1. Partner could be argued to be naive in bidding 4
♠ - she
knows that the alert is incorrect!
2. The ruling was non-contentious (we had won on the night, whichever way the ruling went). But there is an argument that 3
♥X and 4
♥X should have been weighted into the ruling!
3. What an ugly 2
♥ vulnerable overcall!
Universe 1 2NT is not alerted and is natural.
Universe 2 2NT is alerted and on inquiry is described as showing heart support and at least invitational values.
What do you bid?
I am particularly interested in reasons for any change of bid in Universe 2

I might bid 3♣ in both universes but many players would act differently depending on context.
