NAMYATS is a convention where 4img_site/clubs.gif opening means solid 7img_site/hearts.gif+ cards and 4img_site/diamonds.gif opening means solid 7img_site/spades.gif+ cards - solid suit means 7+ cards ahead by AKQ. This convention was used by the 1951 world champion Samuel Stayman and his partner Victor Mitchell in the years of 60 - Namyats is Stayman inverted.

Today Namyats is used in international competitions by many advanced partnerships, but each one has specifics rules for this convention, so here we also established restrictions to
strengthen the convention.

Playing Namyats partnership knows that an opening in 4
img_site/hearts.gif/4img_site/spades.gif denies a solid suit like AKQxxxx and this may be important to avoid search the hand with 4nt asking for aces considering that the open of 4img_site/hearts.gif/4img_site/spades.gif could even be opening with a suit like QJ986532!

Rule#0: The open of 4img_site/clubs.gif promise 7+ cards AKQxxxx in Hearts and the open of 4img_site/diamonds.gif promises 7+ cards AKQxxxx in Spades. In both cases this open denies additional Ace or 2+ Kings or a void. So the hands below are all valid for Namyats:
a)
img_site/spades.gifimg_site/hearts.gifAKQxxxxx img_site/diamonds.gifJx img_site/clubs.gifKx => opening in 4img_site/clubs.gif;
b)
img_site/spades.gifAKQ8654 img_site/hearts.gifimg_site/diamonds.gifJxx img_site/clubs.gifxx => opening in 4img_site/diamonds.gif;
c) img_site/spades.gifimg_site/hearts.gifAKQxxxxx img_site/diamonds.gifJx img_site/clubs.gifKx => opening in 4img_site/clubs.gif;
d)
img_site/spades.gifAKQ8654 img_site/hearts.gifimg_site/diamonds.gifKQx img_site/clubs.gifxx => opening in 4img_site/diamonds.gif;
e) img_site/spades.gifimg_site/hearts.gifAKQ987xx img_site/diamonds.gifimg_site/clubs.gifKJx => opening in 4img_site/clubs.gif;
f)
img_site/spades.gifAKQ8654 img_site/hearts.gifimg_site/diamonds.gifKxxx img_site/clubs.gifx => opening in 4img_site/diamonds.gif;

Rule#1: the opening of 4img_site/hearts.gif or 4img_site/spades.gif doesn't need A or K at top if
the suit has 8 cards like QJ987654, but can't have 2 aces and
must obey the "Rule of 3 and 2" to be
more safety bid.

Rule#2: 
After the opening of 4img_site/clubs.gif or 4img_site/diamonds.gif (in any position) the
Responder makes the transfer 4
img_site/clubs.gif => 4img_site/hearts.gif or 4img_site/diamonds.gif => 4img_site/spades.gif to
sign-off the auction.
If Responder bids  4
img_site/diamonds.gif (not 4img_site/hearts.gif) after the opening of 4img_site/clubs.gif
or Responder bids 4
img_site/hearts.gif (not 4img_site/spades.gif) after the opening of 4img_site/diamonds.gif
he
is searching for singleton in Opener's hand and then Opener bids his major suit if he has 7222, denying singleton.
opener with singleton in Clubs bids 5
img_site/clubs.gif,
opener with singleton in Diamonds bids 5
img_site/diamonds.gif,
opener with singleton in the other major bids 4nt.

Rule#3: If Responder's first bid is 4nt then this is asking for
the only one king that Opener can have and Opener bids:
- 5img_site/clubs.gif <= no king;

- 5img_site/diamonds.gif <= 1 king;
- 5 on his suit <= KQ (king with Quees of same suit)
Then Responder sign-off the auction in level 5, 6 or 7.

Rule#4: After Responder asking for singleton the 4nt
bid by Responder is still asking for king and Rule#3 is on.

Defenae against Namyats
When opponents open Namyats against our partnership we can use the follow strategic:
1- the double of
4img_site/clubs.gif/4img_site/diamonds.gif is not for penalty is this suit, but is a take out double for the other major, showing been shorter in their major and have support for the other suits.
Opponent      we
    4
img_site/diamonds.gif           double  =>  img_site/spades.gifimg_site/hearts.gifAQJ9 img_site/diamonds.gifK10xx img_site/clubs.gifAQ10x
    4
img_site/clubs.gif           double  =>  img_site/spades.gifQJ10x img_site/hearts.gifimg_site/diamonds.gifK10xx img_site/clubs.gifAQ10

2- If we pass and they stop in their major
now the double is penalty showing we have 3 loser in that major suit but have 4+ sure tricks in others suits without support for the other major (honor second).
