In the auction 1♥, p, 1NT ...
Is 1NT alertable because the pair uses flannery in their bidding system
and they are could be skipping a 4 card ♠ suit?
Not that I know of, this would be something new... If asked, the pair must disclose this, but I do not think that it warrants an alert.

If the ♠ bid promises 5 ♠'s, then the 1♠ is alertable.
Correct for the time being, I'm not sure if ACBL has already changed it, but ACBL was discussing making 1 level responses that are natural and promise 5 not alertable... For the time being, I would alert anyway. I don't play the F Word so I'm not sure about 1

♠ regulations, but why bypass it, what if partner is 6-4 or something?
