2 — Transfer to Hearts

WestNorthEastSouth  
  1NT Pass 2 Transfer to hearts
Pass ?      
2 2 or 3 hearts, any strength
3 4 hearts, any hand except a very minimum 3=4=3=3 (pretend you have 3 hearts)

If 2 is doubled, bidding 2 shows 3-card support; otherwise, you should pass. Redouble also denies 3-card support and shows good enough diamonds (good five-card suit) to suggest playing here. If the next player bids over 2, opener needs 4 trumps to compete to the 3-level. The Law of Total Tricks (LOTT) suggests that there is some safety at the 3-level with a 9-card fit, even when responder is very weak.

In general, you should choose to show a second suit before shortness (by a splinter bid), unless the second suit is of poor quality. If we have a 5-4 or 6-4 fit, and a 4-4 fit, the 4-4 will produce more tricks because we will be able to take discards on the five- or six-card suit. Even if you don’t have a secondary fit, partner will be able to get a better feeling for how the hands fit. If you have QJx in partner’s second suit and Axx in an unbid suit this is much better than vice-versa.

  1NT Pass 2 Transfer to hearts
Pass 2 Pass 2♠ 5+ hearts, 4+ spades, slam-try
Pass ?      
2NT Denies a fit in either suit
3♣ Cue bid in support of spades
3 Cue bid in support of spades
3 3-card heart support (or a minimum 3=4=3=3 — opener “Super Accepts’ with 4-card heart support), agrees hearts as trumps
3♠ ?

Note

This is consistent with other two-suited auctions. It is better to return to the first suit with support and cuebid for the second as sometimes raising the second suit puts us above 3NT, for example:

WestNorthEastSouth  
  1NT Pass 2 Transfer to hearts
Pass 2 Pass 3♣ 5+ hearts, 4+ clubs, slam-try
Pass ?      
3 Cue bid in support of hearts
3 3-card heart support
3♠ Cue bid in support of hearts
3NT Denies a fit in either suit
4♣ The only way to agree clubs as trump
WestNorthEastSouth  
  1NT Pass 2 Transfer to hearts
Pass 3 Pass ? 4 hearts, not a minimum 3=4=3=3
Pass Not enough for game
3♠ 5+ hearts, 4+ spades, slam-try
3NT No second suit, slam-try
4♣, 4 5+ hearts, 4+ in the minor, slam-try
4 To play
4♠ Unused
4NT RKCB (normally doesn’t occur after a transfer, but the super-accept set hearts as trumps)

This is consistent with the theme of showing your second suit as a priority on all slam-going hands.

Don’t confuse 1NT - 2; 3 - 3NT with “Serious 3NT”. On this auction we are primarily concerned with shape. If 3NT was “Serious” it would, for example deny a spade control, whereas on this auction 3♠ shows a spade suit, not a control. Another clue to avoid the confusion is that “Serious 3NT” only applies when both hands are relatively unlimited, whereas on this auction opener has a strict range, so there is no need for a “non-serious” cue bid.

2 — Transfer to Spades

WestNorthEastSouth  
  1NT Pass 2 Transfer to spades showing 5+
Pass 2♠ Pass ?  
Pass Not enough for game
3♣ 5+ Spades, 4+ clubs, slam-try
3 5+ Spades, 4+ diamonds, slam-try
3 5+ Spades, 4+ hearts, slam-try
3♠ 6+ Spades, invitational to game
3NT 5 Spades, choice of games
4♣ 6+ Spades, singleton club, slam try
4 6+ Spades, singleton diamond, slam try
4 6+ Spades, singleton heart, slam try
4♠ 6+ Spades, mild slam try, probably 6-3-3-2 or 7-2-2-2
4NT invitational to 6♠ or 6NT, probably 5-3-3-2. 5♠ by opener is to play. (To bid RKCB, use a Texas Transfer.)
5♣ - 5♠ Unused
5NT Choice of slams between 6♠ and 6NT

Continuations follow the same principles as a transfer to hearts, except to note that if the majors are of equal length (5-5 or 6-6), we always transfer to spades first.
