Kaplan Style Inversion over 1H Opening


Kaplan Style Inversion Over 1


This could be used in 1st and 2nd seat inverting the forcing NT and 1♠ response to 1 when midchart conventions are in effect.

1♠: 0-4 Spades acts like a forcing NT
            1NT: (11)12-14(15) HCP balanced or 4+ Diamonds
                        2♣: ask
                                    2: 10-13 HCP 4+ Diamonds
                                    2: (11)(12)-13 HCP balanced
                                    2♠: 14-(15) HCP 4 Diamonds
                                    2NT: 14-(15) HCP balanced
                                    3: 12-13 HCP 5+ Diamonds
            2♣: 4+ Clubs 10-14(15) HCP
            2: NF 5+ Hearts 4 Spades 10-14(15) HCP

essentially Flannery and can play same responses at this point

            2: 6+ Hearts 10-13 HCP
            2♠: 5+ Spades and Lebenshol is in effect after this
            other bids retain their normal meaning

1NT: 5+ Spades
            2♣: (11)12-14(15) HCP balanced 2533 or 4+ Clubs
            2♠: 3+ Spades non-forcing
              2NT: 4+ Spades good fit and extremely good distribution
              3♠: 4 Spades good fit and good distribution (encouraging) Other bids similar to responding to over a 1♠ bid

Optional Treatment - 2NT as Puppet Stayman


1.1.       Use of 2NT as Puppet Stayman over 1NT


Have come up with a way to use regular Stayman to ask for 5-card majors in some case to view this method click: http://transferprecision.blogspot.ca/2012/06/using-regular-stayman-as-puppet-stayman.html

We want to use Puppet Stayman over 1NT and open 1NT with a 5-card major more freely, I propose you use 2NT. The 2NT bid will not be of much use, as now you will want to check for a 5-card major on a lot of hands. So with hands you still want to invite with 2NT, either pass or blast to 3NT. I have taken advantage of the fact that 2NT is one step lower than the traditional 3 puppet Stayman to mask which suit opener has a 4-card major in. It is only shown if responder asks for the suit. The use of 2NT avoids a lead directional double of 3♣.  Responses are simple

With a 5-card major bid 3©/3♠.

With a 4-card major bid 3♣. Then 3¨ asks for 4-card major 3NT is bid with both majors, 3/3♠ shows a 5 card suit with 3 cards in other major, 4♣, 4¨ is a natural slam try probably with a 5 card suit this bid also has same meaning after asking opener to show 4-card major.





With no 4 or 5 card major bid 3¨.

Other bids over 1NT retain their meaning.
