Namyats Convention: 4C and 4D Transfer Openings Explained

By Nir KhutorskyIsrael Open8 min readUpdated 2026-11-01

Namyats is a pair of transfer openings at the four level: 4♣ shows a strong preempt in hearts, and 4♦ shows a strong preempt in spades. Opener holds a long, nearly solid major and about eight to nine playing tricks; a direct 4♥ or 4♠ opening then shows a weaker, purely preemptive hand.

Partner either signs off in the major or bids the step in between (4♦ over 4♣, 4♥ over 4♦) to show slam interest. The convention was devised by Victor Mitchell, and the name is his partner Sam Stayman's surname spelled backwards. It is also called Mitchell transfers, and in Britain the same 4♣ and 4♦ transfer openings are often called South African Texas.

What a Namyats Opening Shows

OpeningMeaning
4♣Seven or more strong hearts, about 8-9 playing tricks
4♦Seven or more strong spades, about 8-9 playing tricks
4♥Seven or more hearts, about 7-8 playing tricks: a normal preempt
4♠Seven or more spades, about 7-8 playing tricks: a normal preempt

A typical 4♣ opening: ♠7 ♥AKQJ10643 ♦A5 ♣92. That is eight heart tricks and the ♦A: nine tricks. It is too strong for a plain 4♥, because partner would pass with two aces and miss a slam. It is not a hand for 1♥ either: you have little defense and want to take away the opponents' bidding room.

The rule of thumb: the suit should be solid or nearly so (one loser at most), and the hand should have no more than about one or two losers outside. A Namyats opening is a game you expect to make on your own, with a hint of slam if partner has the right cards.

Rule of Thumb

Namyats: 4♣ = strong hearts, 4♦ = strong spades, both about eight to nine tricks. Direct 4♥ and 4♠ are the weaker preempts.

You are the dealer and your partnership plays Namyats. What do you open?

Namyats, 4 of a Major or 2 Clubs? Three Hands

The hardest part of Namyats is choosing between it and its neighbors. Count playing tricks, not points:

HandPlaying tricksOpening
♠KQJ108752 ♥6 ♦Q5 ♣84About 7 (the ♠A is missing)4♠, a normal preempt
♠AKQJ10652 ♥A4 ♦83 ♣79: eight spades and the ♥A4♦, Namyats
♠AKQJ1065 ♥AK4 ♦A3 ♣7About 10, with 21 HCP2♣, strong and artificial

The first hand has no defense and no slam potential unless partner has a lot, so it preempts. The second hand needs only the right ace or a fitting king from partner to make slam, so it shows its strength with 4♦. The third hand is too strong for any preempt: it can make game opposite almost nothing and slam opposite very little, and its three top cards outside the trump suit are exactly what partner needs to know about.

Seat and vulnerability matter less for Namyats than for weak preempts, because the hand is built on tricks rather than on the hope of a cheap sacrifice.

Common Namyats Mistakes

  1. Passing the opening. 4♣ and 4♦ are artificial. Responder always bids.
  2. Opening Namyats on a broken suit. With two or more trump losers, slam is unlikely and partner cannot judge. Open a normal preempt.
  3. Relaying with the wrong values. The relay asks for slam. Responder needs aces or key kings, not a pile of queens and jacks.
  4. Forgetting the direct 4♥ and 4♠ are now weaker. Partner should be slower to bid slam over them than before.
  5. Not agreeing on the continuations. Decide what opener does after the relay and whether a direct 4NT is key-card Blackwood before you play it.

Responding to Namyats

After 4♣ (hearts):

ResponseMeaning
4♦Artificial relay: slam interest in hearts
4♥Sign-off, no interest in slam
4♠Natural, a big one-suited spade hand (rare)
6♥To play

After 4♦ (spades):

ResponseMeaning
4♥Artificial relay: slam interest in spades
4♠Sign-off, no interest in slam
6♠To play

Responder needs very little to bid game: opener has promised eight or nine tricks on his own. The question is only whether slam is possible, so responder counts aces and other controls, not points.

After the relay, the simplest agreement is that opener bids his major, and responder takes over with Roman Key Card Blackwood or a cue bid. More detailed versions let opener show a side ace or a shortness instead of bidding the major. Many pairs also play a direct 4NT over the Namyats opening as key-card Blackwood for opener's major. Agree both.

Tip

Never pass a Namyats 4♣ or 4♦. It is artificial, and opener may have a void in the suit you leave him in.

4♦ (strong spades) - 4♥ (relay) - 4♠ - 4NT (key cards) - 5♠ (two key cards with the queen) - 6♠.

North has ♠AKQJ9752 with the ♦KQ outside: eight spade tricks and one more from diamonds, a perfect 4♦ opening. A plain 4♠ would hide the strength.

South has the ♥AK and ♣AK. That is a lot of help for a partner who already has eight tricks, so South makes the slam-try relay, 4♥. North bids 4♠, the simplest reply. South now asks for key cards with 4NT. North answers 5♠: two key cards (the ♠A and ♠K) plus the trump queen. South holds the other two aces, so only one key card is missing: the ♦A. South bids 6♠.

Double dummy, 6♠ makes twelve tricks: eight spades, two hearts and two clubs, losing only the ♦A. Without Namyats, a 4♠ opening would usually end the auction, because South cannot tell a weak preempt from this hand.

Note who declares. North named spades first (at 4♠), so North plays the slam. If South had signed off with 4♠ directly over 4♦, South would have been declarer.

Why Play Namyats?

  1. It separates two kinds of four-level openings. Partner knows whether you have a weak preempt or a near-game hand, and judges slam and sacrifice decisions better.
  2. It leaves a step for a slam try. The relay sits below game, so responder can show interest without going past four of the major.
  3. It keeps one-level openings cleaner. Strong one-suiters that would otherwise open 1♥ or 1♠ and jump later have their own bid, so the one-level openings cover a narrower range.
  4. It still preempts. The opponents must start at the four level, often without room to find their own fit or a cheap sacrifice.

The cost: you lose natural 4♣ and 4♦ preempts. With a long minor and a preemptive hand, you open three or five of the minor instead. Many players accept that trade: a missed major-suit slam costs far more than a lost minor-suit preempt.

Namyats in Competition

If the next player doubles 4♣ or 4♦ (often to show the suit or ask for its lead), responder's calls keep their meaning: the relay still shows slam interest, and the major is still the sign-off. A redouble shows general strength. If they overcall, double is usually for penalty, because your side has a known long major and limited defense outside.

Namyats vs Other Ways to Show a Strong Preempt

  • Plain 4♥ / 4♠. Simple, but one bid covers both weak and strong hands.
  • Strong 2♣. Works for big hands with high cards, but a one-suiter with 14 points and nine tricks is awkward to describe after 2♣, and the opponents get room to compete.
  • Texas-style transfer after 1NT. A different idea: Texas transfers are responses to 1NT, not openings. The British name South African Texas comes from a variant of Texas, but the openings are the same as Namyats.

Frequently Asked Questions

What is the Namyats convention?

Namyats uses 4 club and 4 diamond openings as transfers to strong preempts: 4 clubs shows strong hearts and 4 diamonds strong spades, with about eight to nine playing tricks. Direct 4 heart and 4 spade openings show weaker preempts.

Why is it called Namyats?

It is Stayman spelled backwards. Victor Mitchell devised it and named it after his partner Sam Stayman, who gave his name to the Stayman convention.

How do you respond to a Namyats opening?

Bid opener's major to sign off. Bid the step in between (4 diamonds over 4 clubs, 4 hearts over 4 diamonds) to show slam interest. Never pass, because the opening is artificial.

What is South African Texas?

It is the British name for the same 4 club and 4 diamond transfer openings. Pairs differ on what strength the transfer and the direct major opening show, so ask.

Who declares after a Namyats opening?

The player who first names the major. If responder signs off in 4 of the major, responder declares. If responder relays and opener bids the major, opener declares.
