Benefits of Transfer and Retransfer Bids

Lets see how it works over 1M opening –

1S – DBL – 1NT ( shows C – may or may not bid again , with or without FIT , may have good 6-

                               card good C suit and invite in NT later or support the M at 2-3-4 level )

                                   2C ( shows D suit – may or may not bid again like above )

                                    2D ( shows H suit – may or may not bid again )

                                    2H ( Good raise / 7-10 points OR even more when responder will most likely bid 

                                     Game or double opponents for Penalty )

                                    2S  ( POOR Raise = 3/6 points )

                                     2NT  ( Balanced Limit raise or better with 4+ trumps and NO other feature

                                                like a good side suit or a splinter to highlight.

                                      3C/3D/3H  = MINI/MIDI splinter

                                       3S = Preemptive

                                       3NT = ( can be played as Game force hand with BAD trumps and stoppers outside )

                                       4C/4D/4H = ( Good 5-4 / 6- 4 in the bid suit and trump fit , may make a slam at

                                                              most on a finesse               

                                         4S = ( distributional /anti slammish with at most 2 controls outside , K=1/ A=2 )

                   Similarly after 1H opening –

                  1H – DBL –   1NT ( shows C , may or may not bid again)

                                          2C  ( Shows D suit )

                                           2D  ( Good Raise with 3-4 trumps )

                                            2H  ( Poor raise )

                                            2NT ( Limit raise or better )

                                            2S/3C/3D = MINI/MIDI splinter

                                            3H = Prremptive

                                            3S/4C/4D = Good 5-4/6-4 fit in the bid suit and 4+trumps

                                            3NT  = Game forcing values with 4 poor trumps

                                             4H = Preemptive type / distributional / anti slammish
