I believe (1N)-2D-(P)-2S is usually played as, "to play opposite spades, invite+ opposite hearts" or "to play opposite spades, at least a preemptive raise of hearts". Wouldn't it be better to play it as "invite opposite either major"?

The losses would come when we wanted to be in game opposite hearts but not spades, and partner actually has hearts. This seems exceedingly rare, as the opponents will nearly always compete to 2S on such hands. The advantage, of letting responder invite then stop in 2S, is surely much larger.

Am I missing anything?

Yes - the ox gets to play the dummy.

You have to be able to find a fit quickly regardless of partner's major. With your suggestion, you have to bid 2♥ with hearts which doesn't promise anything. You'll rarely have an invite for either major in the above sequence, but you'll often want to be able to preempt them if you have a fit and 2♠ showing hearts helps.

If you are playing this method, then I think you need to have a separate bid, perhaps 3♦ as invitation in both. I would say the risk of going one off when you have a rare double invitation is less than the loss of being able to invite in the more common hearts alone.

Perhaps 2NT or 3♣,with transfer replies so that the 1NT opener is on lead.

2nt is used as "invite opposite either major"... Yes, it would be nice to invite and still play on the 2-level when declined, but most of the time you cannot. I don't think making an exception here is worth the memory strain.

Nice idea, I'm going to suggest this to my one partner that I play 2D multi over their NT with... most likely he will think I'm nuts but it seems good to me.

[MickyB]

Great, let me know whether it works

I know some play -

X = pens
2C = majors
2D = good 2M overcall
2M = bad 2M overcall

With this refinement, that could become -

2D = good 2H overcall or any 2S overcall
2H = bad 2H overcall
2S = 4S,5+m
2N = 4H,6+m
