Fake Jump Shifts

[Gerben42]

How to avoid your fake jump shifts with a regular partner? Here's a solution.

 

Step 1: Open all balanced 18 - 19 hands with 1♣

 

Step 2: Play that 1♣ - 1M - 2♦ is a MULTI REVERSE: Either a natural reverse or 18 - 19 balanced. As this is the lowest possible reverse bid, there is room for some asking around (2 of the other major).

 

After these two steps, the 2NT rebid has become free.

 

Step 3: Play that 1m - 1M - 3m shows an INVITATIONAL 1-suiter with 3-card support for partner's major (Bridge World Death Hand)

 

Step 4: Play that 1m - 1M - 2NT shows an invitational 1-suiter without 3-card support, or any GF 1-suiter.

1♦ - 1♠

2NT* - 3♦ (Minimum with only 4-card ♠)

3♥ (values or control) - 3NT (I stop ♣)

4♣ (confirms 3♥ = control) - 4♦

4♥ - 4♠

4NT - 5♣

6♦

Why would 3D deny a 5 card spade suit? If partner has 3 spades he has a "GF 1 suiter" and if he does not have a GF hand he does not have 3 spades. I can't imagine what you are bidding with Kxxxx Qxx xx Jxx or something if it's not 3D. It seems like opener would have a 3S bid after 3D to show 3S and a GF 1 suiter in diamonds. While this seems like a good start to the auction, responder has no idea what to do. He could easily belong in 3N if his partner had a stiff club, but on this hand partner is a stiff heart. In your auction opener ended up driving past 3N himself. To me that is not good. I think 1D 1S 3C is a better start to the auction because partner will know he needs good hearts to bid 3N. We can play 3N after that start to the auction, the way your auction started things are just too cluttered to ever play 3N.

 

There are solutions to these problems but I think you are approaching it the wrong way. You are not utilizing the 2H bid at all in this auction which, since it's lower and is not a NT bid, is a more logical bid to utilize for artificial things than overloading your 2N bid.

 

You are also creating new problems by opening 1C with all 18-19 balanced hands.

How to avoid your fake jump shifts with a regular partner?

I think you are on the wrong track.

 

In theory if a bid is forcing the subsequent bid can/should be forcing since the 1st forcing bid can be used to show the subsequent non-forcing bids & that way you can get the most forcing bids possible & are able to show more hand type. In practice its a different story since you dont want to hog all the bidding space (partner need some space too) & sometimes 1 bid for all nf hand isnt enough. Also you dont want to give lead directing X for no reasons.

 

1 thing im sure is that

 

1D----1S

2H

 

to play 2H as true reverse is just plain bad. The cheapest reverse is a much too valuable bidding spot & in standard it is used less then 5% of the times. Also using 3S as INV is dubious. Why go down in 3S when you can play 2S  ??

 

An easy & effective solution is to play that 2H is a weak S raise or a GF raise (maybe 3 cards) or a 18-19 bal (dont worry if partner bid 4S expecting you have 4♠ 12-14)  your extra strenght will allow you to bid again) and that 2S is a 15-17 raise. That way you will never play 3S for no reason. You need to find other way to show the H reverse (2Nt & 3S are free now)

 

Another solution is too allow more flex for the reverses (even into a 2 card fragment).

Of course if you reverse into 2H with AQx,KQ,Axxxxxx,x then partner shouldnt go to 4H at the 4 level without a D fit. Its easy to make intelligent continuations after a semi-natural reverse.

Those who want to avoid fake-jumps shift are simply overloading 2Nt instead of using the full potential of the cheaper reverses. Even Strong jump shift are better played as fragment then "true jump shift" IMHO.

As for opening a non-forcing 1C with (43)42 shapes is something i dont recommend especially red since the chance to passed-out is fairly high.

With 1♣ openings and 1♦-1♠ sequences you can easily overload one or more reverses. However, what do you do after 1♦-1♥?? And do you use some similar tools after 1♣-1♦?

Maybe you can use 1♠ as your "fake reverse" in this auction. Responder almost never passes this bid, since even in standard it can be bid on as much as an 18 count.
