"Well to be perfectly honest, in my humble opinion, of course without offending anyone who thinks differently from my point of view, but also by looking into this matter in a different perspective and without being condemning of one's view's and by trying to make it objectified, and by considering each and every one's valid opinion, I honestly believe that I completely forgot what I was going to say."

spade, spade, spade. It's matchpoints. Let's not give anything away.

awn poses "An opening lead problem; matchpoint pairs:"

I rank
If LHO promises 4s, then , , . .
if LHO might have 4s, then , , , .
If LHO denies 4 M, then , , , .

For many partnerships this sequence would deny 4s with LHO (whether or not opponents remember their agreement), so a lead seems safe and normal except when this sequence explicitly promises 4s.

I'd lead J on the first, which feels about as likely to give a trick away as a club and marginally more likely to hit an establishable five-card suit (given P couldn't double Stayman, which he might have scraped with Axxxx and something outside). Other than that, spade.

At the end of the auction, North mentioned that there had been a failure to alert, and that 2NT did not guarantee a four-card major. After this, West lead K face down on the table. East then asked if 2NT could ever include a four-card major, and North said that it could not. Of course, the club king lead was not a success.

It seems that there was some amount of misinformation here (there's a difference between 2NT "may or may not have four spades" vs. 2NT "denies four spades") but according to the poll here it does not much effect people's leads. The director was not called at the table; I'm curious what the ruling would've been.
