    Transfer Methods after a Takeout Double of 1 of a Major

    Transfers on the sequence (1 of suit)-X-? make a lot of sense. With weak hands, responder will both conceal the declarer’s stronger hand and put the strong defender on opening lead. (Point ranges given assume a precision style system with 8-15 limited openers, and methods don’t apply

    over the strong 1C)

Transfers over 1M:

    Major suits are treated differently than minors since space is more at a premium.

1M - X - ?:

    P weak without support or a long suit, or various inv+ without support

    XX a transfer to 1NT showing the usual 1NT bid and decent but limited

    values (~8-11), similar values but a 2 suiter, an inv+ hand with 3 card support, or

    some GF hands without support

     1S natural but NF, 4+ cards and constructive or invitational values (over 1H)

     1N transfer to clubs or lead directing raise

     2C transfer to diamonds or lead directing raise

     2D transfer to hearts or lead directing raise (over 1S)

    2M-1 constructive raise (7-10), 3+ cards

     2M preemptive raise (0-6), usually 3 cards

     2N Jordan (4+ card raise, limit+ values)

     3M preemptive raise (0-6), 4 cards

Jump new suit bids are weak natural preempts.

Discussion and continuations:

Suit Transfers

    When weak, transfers to the 2 level usually show a 6+ suit (like a weak 2 bid). Weak hands with support may use a transfer to make a lead directing bid instead of the normal 2M or 3M preemptive raise, correcting back to partners suit if given the opportunity. No hands with 3+ support start with a transfer, so this correction should not be construed as forward going.

    Stronger hands may transfer to a 5+ suit, and then bid again to show invitational or better values. 2NT, new suits, and a raise of the transfer suit are all natural and invitational. Responder may jump in his second suit to force to game.

    Suit transfers should generally be accepted by opener, even with only singleton in the transfer suit. With a very good holding, opener may super-accept the transfer. With a void, a rebiddable major, or a good 5 card second suit, opener may refuse the transfer and bid (or rebid) his suit. Neither accepting nor refusing the transfer show extra values. Maximum and distributional opening hands may jump in their own or secondary suit (as over 1M-1NT forcing) showing 6/5+ or shapely 7+.

NT Transfer using XX

    XX is nominally a transfer to 1NT, and while not always balanced, promises constructive or better values. These XX hands will often have 2-3 card support for partner’s major given X’s shortness

    especially over 1H when partner will deny 4 spades for the 1NT hand (over 1H, 31(45) might have only 1 card, and rarely over 1S 0(544) might have none). If the advancer passes, opener with a good suit and a good hand is invited to pass, expecting to make 1M-XX. Opener’s with weaker

    hands/suits must take the transfer and bid 1NT.

    Balanced or semi-balanced hands will happily pass 1NT. Bidding a new suit shows the cheapest of suit a constructive two-suiter (DONT), usually at least 5/5. If instead responder later supports opener’s suit with 2M or artificially with 2M-1 (not needed for DONT), he shows the 3 card GF or

    invitational hand respectively. Game forcing single suiters jump in their suit after 1NT.

To summarize, after 1M-X-XX-P;1NT-P-?, bids are:

     P constructive, balanced or semi-balanced

     2C constructive C+D (over 1H) or C+? (over 1S)

     2D constructive D+H (over 1S)

     2M-1 invitational 3 card M raise (then 2M response shows a weak opener)

     2M GF 3 card M raise

     2S GF single suiter (over 1H)

     3m GF single suiter

     3H GF single suiter (over 1S)

Meanings for 2NT or 3M+ undefined for now...

    As with suit transfers, opener with a distributional hand and a second 5+ card suit may bid his second suit, refusing the transfer to 1NT and being unwilling to sit for the XX. Responder should now treat the auction as similar to the uncontested 1M-1N*-2Y. Constructive hands must take a preference between opener’s suits. Hands with support will bid 3M or 4M, and new suits are GF (note that invitational single-suited hands can transfer initially).

Pass Weak or Trap

    The trap pass by a ~12+ balanced hand without support is based on the very likely assumption that the weak advancer will be forced to takeout his partner’s double (or that doubled overtricks will be sufficient compensation). If responder initially passes the double but subsequently doubles the opponents, this if for penalty. If responder bids instead, it shows this strong hand but with a poor holding in the opponents suit unable to double (a new suit shows a two suiter short in opener and opponent’s suit, while a cue bid is more balanced and asks for a stopper).

    After 1M-X-P-P, opener’s XX is for rescue opposite the weak hand but business opposite the various strong ones. After opener’s XX, 1NT by responder shows 2+ places to play whereas a

    direct suit bid shows a single suit.

    Thoughts for further improvements:

    - modifications for responder a passed hand

    - XX followed by raising 1NT to 2NT

    - a way to show doubleton M support vs not with the inv+ 1 or 2 suiters?

    - competitive agreements over 4 seat’s bids (doubles, completing transfers at higher levels, etc)
