• The purpose of transfers after an opening 2NT is to find a trump fit on hands that don't know where they want to play. There isn't room to use them for delicate investigation on hands that know what trumps will be, but want to know more about partner's hand anyway.
  • System remains on after a double, but is turned off after an overcall.

    any slamTo play, showing a no-loser trump suit at the six level. Not a transfer.
    Cue-bid after overcallTake-out, game-forcing, likely to have slam interest.
    New suit after overcallNatural, at least a five-card suit, game-forcing. Makes no promise as to suit quality.
    Jump shift after overcallIf four of a minor or 4NT, it's ace-asking. Otherwise it's to play and possibly pre-emptive.
    DoubleTake-out if below 4S. To make a takeout double and then keep bidding even when partner pulls it is game-forcing and natural (showing only a four-card suit) up to 3NT or else above that a slam try, agreeing partner's suit. If you want to play in a part-score, all you can do is pass and hope partner finds a reopening double, then make your non-forcing bid.
    RedoubleWants to double the opponents for penalties.


  • All such bids are to be assumed to be weak and pre-emptive, so a reply from partner is non-forcing.
