I am curious :
Can the OP tell us what whoever thought this is not a WKNT opening, considered to be the problem with 1NT?

[Ant590]

I'm not entirely sure what my friend thought the problem was with the NT opening -- it certainly wasn't of the ilk "you only have three tricks" which is a common beginner conception with this type of hand.

I'm happy to report that I won the bet. It's surprising though that you can question your own 'WTP' ideas when someone is particularly adamant...

[kenrexford]

OK.

6X3.33=20-12=8=+2

12+2=14.

Fifth diamond=15.

Diamond 109=+.25

So, arguably 15 to 15.25.

That said, ot seems really dangerous to adjust up by as much as or more than 25% of the total HCP value, until you know something. So, I'd call this a 12-14, but I'm willing to change my position during the sequence and get aggressive later, such as perhaps making a three-card super-accept of a transfer or something.

I will open this hand 1NT.
But it is possible to open 1♦ if you play openers rebid shows 12-16.Then a 2♣ relay helps to show point range and support for partner's major.After a response of 2♣ opener's rebid of 2♦ shows the given hand.

I find it curious that this hand evaluates better than KJT KJT KJT QTxx.

3X3.33=10

14-10=4 (adjust 1)

14-1=13

13+(.25X4)=14

Yep. Technically worse.

Add one more vote for 1NT.

Regarding the people who are counting it as 15 or so points because Aces are undervalued: I thought that this really only applied in suit contracts, and that for NT, something like the fifths count (A=4, K=2.8, Q=1.8, J=1, T=0.4) was more accurate.

[NickRW]

That's right.

Well, this is sort of a suit contract problem, in a sense.

I've said this before, and I believe it to be accurate. Notrump contracts some in two forms -- clouds and T's. A "cloud" notrump contract is one where you have a bunch of junk everywhere and somehow end up with some number of tricks after a long, defensive battle. The KJ10-KJ10-KJ10-Q10xx is a classic "cloud" holding.

The "T" form is one where you hope to beat the opponents to getting your tricks before them. When the 1NT opening is enhanced because of the stem of the "T," meaning a trick source, you want Aces and the hand plays more "suitlike."

The actual hand has a "T" in the diamond suit. Opposite KQx in diamonds, and the third side Ace, you are up to 8 tricks on a mere 21. Add another King, and you have 24 but 9 tricks. Hence, in a sense, the length in diamonds created two extra tricks that were pure tricks because of the purity of the T.
