1C-1D// 1NT

[olien]

So, I was doing system stuff on this auction, and it seems inefficient to use 2M here as natural and GF. So I was wondering what people would recommend.

 

What I have at the moment is something like so:

2m natural NF

2H similar to stayman, but not sure about which continuations are best

2S size ask

.......2N...minimum

.............3m invitational

.............3M shortness with both minors

.......3C...maximum

............3D natural invitational

............3M shortness with both minors

2N dunno what this should be?? maybe completing some of the 2H hands which will be used for responder to pattern out.

3m natural GF

3M shortness with long diamonds

 

 

Some input would be welcome.

Thanks

Depends a bit what you respond on 4D4M GF and 4+D4M INV. I quite like being able to bid 1C:1D, 1NT:2C, 2D:2M on a 4M5D invite.

 

I quite like 2M as natural GF - it's a basic principle that unbalanced hands should describe themselves to balanced hands and not vice-versa, and you want the hand declaring 3NT to not have described itself. I guess you could invert the majors here if you want to further increase the likelihood of the relatively unknown hand declaring.

With 4M 4♦, we respond 1M. 1♦ only has 4M if 4M 5+♦ GF.

 

I was thinking something along these lines:

 

1♣-1♦; 1NT:

2m natural NF

2♥ 4M 5+♦ GF

...........2♠ relay

......................2NT 4♥ (then 3♣ relays w/o ♥ fit, and 3♦ relays with)

......................3♣ 4♠ 5♦ (then 3♦/♥ relay w/o and w/ fit for M)

......................3♦ 4♠ 6+♦ (then 3♥/♠ relay w/o and w/ fit for M)

2♠ 4+♦ 4+♣ GF

...........2N relay

..................3♣ 5+♦ 4+♣ GF (then 3♦ relay for short, 3M=values)

..................3♦ 6+♦ no M short (3♥ relay)

..................3M shortness, 6+♦, slam interest

2N Natural INV

3m Natural INV

3M shortness, 6+♦, game only

 

 

so after 2♥-2♠:

2N 4♥ 5+♦

.......3♣ relay without ♥ fit

..................3♦ 4♥ 6+♦ (then 3♥ relays for short)

..................3M 4♥ 5♦ showing short

..................3N no short (or stiff H, and just looking for ♥ fit)

..................4♣ 2452, slam interest

.......3♦ relay with ♥ fit (then same steps, just up one, and resp can bid 4M to play)

 

3♣ 4♠ 5♦

.........3♦ relay without ♠ fit

..................3M showing shortness

..................3N no short (or stiff H and just looking for ♠ fit)

..................4♣ 4252, slam interest

.........3♥ relay with ♠ fit (then same steps, just up one, and resp can bid 4M to play)

 

3♦ 4♠ 6+♦

..........3♥ relay for short without ♠ fit (4♣=high short, slam interest)

..........3♠ relay with ♠ fit (then same steps, 4♠=to play)

 

 

and after 2♠-2N:

3♣ 4+♣ 5+♦

..........3♦ relay for short (then 3M=short, 3N=2254 mild SI, 4♣=2254 str SI)

3♦ 6+♦ no short M

..........3♥ relay

...................3♠ ♣ short

...................3N no short, mild SI

...................4♣ no short, strong SI

 

 

I dunno if this has much merit, but input would be welcome.

 

Thanks

How do you play 1♣ - 2♦?

[olien]

We play that as an invite ♣ raise.

 

The other responses to 1♣ are:

2♣ GF raise

2♦ as mentioned

2♥ 5♠ 4/5♥ 4-9ish pts

2♠ mixed raise

2NT natural INV

3♣ weak
