1D (1H)

[straube]

We're playing that 1D=0+ diamonds and 10-15. It can be balanced or be 3-suited or 2-suited with both minors or 6D/4M

 

After 1H is overcalled, thinking....

 

dbl-4+ spades

.....1S-3 spades

..........1N-nf

..........2m-nf

..........2H-invitational+

.....1N-bal

..........2m-nf

1S-bal

.....1N-to play

.....2C-5 clubs, doesn't promise diamonds

.....2D-5 diamonds

1N-minors or six diamonds, less than GI and technically nf

2C-9-13 with 5+ clubs.

2D-diamonds, GI+

2H-clubs, GF

2S-9-11, six spades

2N-GI

 

Remember that we need to give some thought to finding minor suit fits when the auction gets competitive because opener's minor suit holding is very unclear.

 

Any suggestions?

One option might be play straight up transfers over 1♥, i.e.:

 

X: 4+ ♠

1♠: Balanced hands

1N: Transfer to ♣

2C: Transfer to ♦

2D: Transfer to ♥

2♥+: TDB

 

One can extend this idea to 1♦ - (1♠) as well:

 

X: 4+ hearts

1N: Balanced hands

2C: Transfer to ♦, TP or GF

2D: Transfer to ♥, TP or GF

2♥+: TBD

 

As I recall hanp and other play transfer advances even after 2♣ overcall as well...

It might be nice to be able to show both minors. Say I have 3-1-4-5 and don't want to commit to clubs.

 

What does TBD mean?

I think "To Be Determined"

1D (1H)

 

X handles most spade hands

 

1S needs to be more than balanced. It could (for example) handle both minors

because opener can then have the freedom to rebid a 5 cd minor suit and then win either way. So opening 4-3-1-5 opposite 1-4-4-4 and now we find clubs.

 

1N shows clubs, but what's the point range? The bid needs to empower opener to do something. A contract of 2C may be acceptable but we need keep our constructive auction. I think 9+ with a 6 cd suit or 12+ with a 5 cd suit is ok. Opener can raise clubs with a fit either way. Without a fit, he can accept the transfer with a minimum non-fitting hand and play 2C opposite the first. The second hand has to bid again opposite a simple acceptance of the transfer.

 

2C same reasoning for diamonds

 

2D-balanced GF?

 

.....2H-denies a heart stopper?

 

2H-shows 6 spades? maybe 9-11 or 14+ If the hand can be too light, opener

.....will never contribute useful information (like bidding 3S). If the ranges are

....not split, we risk director calls after opener hesitates before signing off in 2S

.....and responder makes one more try.

 

2S-values for 2N with a heart stop?

 

2N-weak, more minors than 1S?

 

3m-preempt?
