In my club my opponents opened 2D with 6 poor spades and only 1 point. Alerted as a weak bid. I Overcalled 2 S with all the royals. Went down 1 in 4 S.
Is it legal to open weak with 1 point?

Where in the world are you playing?

Also

Was it explained as "a weak two in an undisclosed major" or similar, or just as "weak" without any mention of a major (or Multi)?
What is their real agreement about 2D?

Why does this matter? The problem is that you overcalled in the same suit they had. Would you have done any better if they had the expected 5-10 HCP?

The ACBL convention charts mention minimum HCP for normal weak 2 bids (4 in Basic chart, 3 in Basic+). They don't specify a minimum for Multi 2, but maybe we're supposed to presume the same as a natural weak 2.

4 in basic, 3 in basic+. really? who knows this, who violates the minimum and how do they enforce the restrictions in these charts?

The question of OP matters because rules are rules. How does his overcall influence the answer to his question about 1 HCP being legal?

Not sure why you assume he even knew that Opener might have spades rather than diamonds. His post does not mention them explaining it. He certainly should clarify this and where he plays.

The IP address from which the OP was posted is in Ireland. It would appear only Irish regulations are relevant. A quick look at Irish regulations doesn't show any minimum point count for a weak two opening. So the answer to the OP question appears to be "yes, it's legal."

No minimum for the agreement about a preempt here in Italy either.
But the minimum be able to Announce a weak two as "weak" is 6 HCP (too high, IMO). So if the minimum is 0 HCP it is correct to alert, but I would not retain an explanation of "weak" without a minimum as sufficient disclosure (in theory it begs further questioning, but the most likely explanation is that they have a normal agreement but do not know to announce).

Even if it's illegal, there has to be damage in order for the TD to award an adjusted score for the NOS, although they could issue a PP against the offenders.

If the explanation didn't make it clear that Multi shows an unspecified long major, that could indeed have caused this damage. But the question was specifically about the point count, I assumed the rest was made clear.

The OP does not make it clear if the explanation made it clear that it was Multi, rather than diamonds. He might have deduced it was intended as Multi only later.
The only clear question it asked was about the points count.
I agree it's a pretty poor post and the author should pay more attention and clarify when requested.
