I open 1♦ and next player overcall 1NT.

After the hand we discover that he had a ♦ singleton.
Is it a psychic or should he alert ?

Thank you to take time to respond.

I am very intrigued.

You need to ask the player who made the call, not us

most likely it's just a clueless player who doesn't understand what 1NT should have there.

a psyche has to be deliberate. bad players often misdescribe their hands unintentionally. as for alerting, they don't have to alert that they're bad players.

I've seen plenty of players bad enough that the bid shows pts period and nothing else. Of course they don't know what an alert is either.

If there is a director available they need to sort it out (if the stiff was smaller than a queen it should be as verboten as an opening 1nt). If there is no director you can give a free lesson, civilly of course or my tendency is to wish them luck with the rest of their game. They will need it.

I think he was referring to the 1N bidder, not the opener.

Two possibilities. The 1N bidder was a new player, or, 1N was some sort of takeout call like I play.

You kind of need to tell us the environment. I've seen a player with 5521 shape (5/5 majors), bid 1nt after their partner opened 1c to show their 6-9 pt hand. Needless to say, that was not what I would consider as a strong player. I was quietly laughing as he struggled to go down 1 when there was a 9 card spade fit.
