Sleight of Hand / SLAM-SEEKING after STAYMAN
« on: May 21, 2020, 05:02:09 PM »
Playing IMPs. Vulnerable vs Not-vulnerable.

You pick up the following hand:
!S AT — !H KQT9 — !D KJ4 — !C K752

Your partner, dealer, opens with 1NT (15-17). What’s your plan?

I think it will be a consensus 2 !C response, looking for a heart fit. So let’s begin with 2 !C.

1NT – 2 !C – 2 !S - ??

Oops! Wrong major. Still, with a relatively balanced 16 HCP, if partner has a max we want to be in slam. So we simply invite with 4NT, which should be a quantitative raise asking partner to bid 6NT if he is max for his 1NT opening. BUT WAIT! That’s Blackwood, right? Asking for keycards?

NO!

•   It is not Blackwood.
•   It is not RKCB.
•   It is not asking for Aces.
It is a quantitative raise asking partner to bid slam with a max. THIS HAND is the poster child example for why 4NT is NOT RKCB. To initiate RKCB you need suit agreement.

Think of a related auction: 1NT – 2 !D – 2 !H – 4NT

•   What is 4NT?

Let us, for the sake of argument, assume a certain degree of bridge knowledge in a standard 2/1 structure. Let us also assume Texas is on the CC. With those caveats, it’s clear that 4NT is NOT RKCB. Why? Because there has been no suit agreement. The transfer promises only five-plus in the major and opener may only have two, therefore, we have not yet identified a fit and—there is no suit agreement.

So how do we agree to a suit after a positive Stayman response?

There are multiple methods. Baze, Modified-Baze, Goldway slam try, and others.

The Baze Convention is what is currently used if playing BWS2017. It is so prevalent that I would call it “standard.” Although I slightly prefer Modified-Baze, if I sat down opposite a random expert, I would play Baze undiscussed and would expect my Baze bids to be understood.

In a nutshell:
1.   Three of the other major shows unspecified shortness. (Yes there is a method to determine where.)
2.   4 !C is RKCB for opener’s major.
3.   4 !D is a balanced (no shortness) slam try agreeing to partner’s major.
4.   4NT is a balanced slam invite with four of the other major.

There is more to it than that, and I have attached a more in-depth summary of Baze (it also includes Modified-Baze). It is not a difficult gadget to learn.

Try it. I think it will improve your bidding in Slam-Seeking auctions after Stayman!

Sleight of Hand / Your Move!
« on: April 12, 2020, 02:10:56 PM »
Prior to your first morning coffee, you sit for a couple of hands and see this:

!S KQ6 !H AJT73 !D AJT86 !C --

LHO is dealer and passes. Your partner OPENS 2 !C!

WoWWWW! This has possibilities!

Your RHO overcalls 3 !C. No worries, you have support for any suit partner bids. With this powerhouse, opposite a 2 !C opener just pass to show values (double would be a double negative) and see what develops. You pass (alerting it as "values"), and wait . . .

What will partner do?

Your partner trots out 4 !C.

WoWWWW! So far the auction has been:

(P) - 2 !C - (3 !C) - P
(P) - 4 !C - ( P )  - ??

Do you use science? Jump? You're already at the 4-level . . .

Your call.
