Miles Responses To Two No Trump Opening Bids

The origin of this conventional method is credited to Mr. Marshall Miles, of Sun City, California, United States, and who married Betty Miles, also a distinguished bridge player. The idea behind the concept is for the responder to be able to show a variety of holdings with artificial bids at the three level and at the four level with natural bids.

 

The following schematic should clarify and illustrate the application of this conventional method. The reader should be mindful of the nature of the presentation on this web page, in that the continuances with possible rebids by opener are ended and separated by line-spacing, whereafter the normal line of responses are re-continued.

Opener   Responder   Meaning
2 NT   3   This first response is Stayman, asking for a 4-card Major suit.
3 Diamonds       If the opener has no 4-card Major suit, then the opener denies by bidding Diamonds.
    4 Diamonds   Following a denial bid by the No Trump bidder, then a bid of 4 Diamonds shows a distribution of exactly 4-4-4-1 with a singleton Club.
3 Hearts       If the opener has both 4-card Major suits, then the opener bids 3 Hearts.
3 Spades       If the opener has a 4-card Spade suit, but not a 4-card Heart suit, then the opener bids 3 Spades.
         
    4 Clubs   Following any positive reply of the No Trump bidder, a rebid by the responder of 4 Clubs is Gerber, asking for Aces or Keycards (Roman Keycard Gerber).
    4 Diamonds   Artificial and establishes the Major suit of partner as the trump suit. This artificial bid is a slam try.

When the responder holds slam values the concept of Miles Responses only allows the responder to first employ the Stayman convention by bidding 3 Clubs and then asking for Aces or Keycards by bidding 4 Clubs as Gerber. This means that the partnership may not bid 4 Clubs directly as Ace-asking or Keycard-asking. As a consequence the first response of 3 Clubs does not guarantee the holding of a 4-card Major suit.

Following a positive rebid of 3 Hearts or 3 Spades by the No Trump bidder, the responder can then bid 4 Diamonds as a slam try. The partnership can agree on several forms for responding and showing controls, Aces, and/or Keycards.

 

Continuances:

Following are other continuances by the responder immediately following a 2 No Trump opening bid by partner.

Opener   Responder   Meaning
2 NT   3 Diamonds   This is a transfer bid to Hearts.
3 Hearts       Partner should accept the transfer.
    3 Spades   The responder is showing a 5-card Heart suit and a 4-card Spade suit.
    4   The responder is showing a 5-card Heart suit and a 5-card Club suit. The stipulation is that if the second bid suit is a Minor suit, then the Minor suit is as long as the Major suit, to which responder transferred the No Trump bidder.
    4 Diamonds   The responder is showing a 5-card Heart suit and a 5-card Diamond suit. The stipulation is that if the second bid suit is a Minor suit, then the Minor suit is as long as the Major suit, to which responder transferred the No Trump bidder.
         
    3 Hearts   This is a transfer bid to Spades.
3 Spades       Partner should accept the transfer. The responder can, as a continuance, bid a second suit showing a two-suited holding. This strongly shows slam interest.
         
    3 Spades   Following the opening by partner of 2 No Trump the responder can bid 3 Spades. Although this bid is considered to be an artificial bid by the responder this first response is a transfer to 3 No Trump, which the No Trump bidder should accept. The responder then passes if a No Trump game contract is the optimal contract.
3 NT       The No Trump bidder accepts the transfer.
    4   If the responder considers worth a slam try, then a continuance bid of 4 Clubs signifies this slam interest. The No Trump bidder must puppet to 4 Diamonds, and the responder then clarifies his holding.
4 Diamonds       The No Trump bidder accepts the puppet.
    4 Hearts   The responder promises a two-suited holding with length in Diamonds and a 4-card Major suit.
    4 NT   The responder promises a one-suited holding with long Diamonds.
         
    4 Diamonds   Following a puppet to 3 No Trump the responder can continue to show slam interest and clarify his holding. With a 4 Diamonds rebid the responder promises a holding with a distribution of 4-4-4-1 with a singleton in Diamonds.
    4 Hearts   With a 4 Diamonds rebid the responder promises a holding with a distribution of 4-4-4-1 with a singleton in Hearts.
    4 Spades   With a 4 Diamonds rebid the responder promises a holding with a distribution of 4-4-4-1 with a singleton in Spades.
    4 NT   This rebid promises a two-suited holding with length in both Minor suits.
         
    3 NT   Following the opening by partner of 2 No Trump the responder can bid 3 No Trump. This first response is artificial and is forcing to 4 No Trump. The No Trump bidder may not pass. The response is a puppet to 4 Clubs. Once the No Trump bidder bids 4 Clubs, then the responder continues to clarify his holding.
4       The No Trump bidder accepts the puppet.
    4 Diamonds   This continuance shows long Diamonds and Clubs of equal or longer length.
    4 Hearts   This continuance shows long Hearts and Clubs of equal or longer length.
    4 Spades   This continuance shows long Spades and Clubs of equal or longer length.
    4 NT   This continuance is not Ace-asking but rather promises a long Club suit of at least 6 cards.
         
    4   Following a 2 No Trump opening by partner a 4 Clubs first response is natural and promises a long, but broken Club suit. The Club suit is not solid.
    4 Diamonds   Following a 2 No Trump opening by partner a 4 Diamonds first response is natural and promises a long, but broken Diamond suit. The Diamond suit is not solid.
    4 Hearts   Following a 2 No Trump opening by partner a 4 Hearts first response is natural and promises a long, but broken Heart suit. The Heart suit is not solid.
    4 Spades   Following a 2 No Trump opening by partner a 4 Spades first response is natural and promises a long, but broken Spade suit. The Spade suit is not solid.
