The benefit of NAMYATS is to differentiate between a strong distributional hand, which may provide a slam opportunity with less opponent interference, and a preemptive bid which has no slam opportunity.
An artificial opening bid of 4 or 4 used to signify a good hand with 7+ card length in Hearts or Spades, respectively. Opener’s hand should hold 8 or 8 1/2 playing tricks with good honors in the major suit, usually accompanied by an outside Ace or King. Conversely, an opening bid of 4 or 4 shows a weak preemptive hand not meeting that criteria.
NAMYATS was created by Sam Stayman who, after creating the Stayman 2 response to partner’s Notrump opener, coined the NAMYATS convention using his name in reverse order (Sam originally suggested the opposite meaning to friends who told him it was backwards; he agreed to their suggestion, saying he would give it his name, albeit with backward spelling of his name!

4 – P; 4 – P; |
