Rebid problem

[lamford]

You've already posted a hand in another forum where you give as a problem what responder should rebid on a 1=5=5=2 five-count with 2 queens and a jack, without any comment about the merits of a 1NT response. So I assume your simulation should include 1=3=4=5 hands such as x xxx Q10xx QJxxx as you seem to think these are a 1NT response.

I originally included only hands with 6-9 points, as you could see from the terms of that simulation. But I then changed this to 5-10 on gnasher's valid protestation that I was living in 1965. Changing the range increased the chance of success of 4H, so I do not think 2H is "obvious". The downside to it is missing a lot of games.

Its obvious that would increase it, since ten HCP is twice as common as 5 HCP roughly.

 

However, partner should basically never be passing 2h with ten HCP unless he has a 1-3 in the majors. Even then he normally has to be 13(45) since hands with a 6 card minor and 10-11 HCP normally have some sequence that shows them, either bidding 3m now or bidding 3m over 1M.

your bid

This hand has created quite a bit of interesting discussion.

 

Fortunately, I would not have to deal with it, as my 3♥ rebid shows 5-5 in the majors with invitational values (approximately 16HCP).

 

Rebid structure after 1♠-1NT:

 

2♣ - 2+ clubs, minimum opening without 6 spades, 4 hearts or 4 diamonds. (Using 2♣ as the rebid on all hands without a real second suit other than clubs allows responder to bid 2♦ BART on appropriate hands).

2♦ - 4+ diamonds, minimum hand.

2♥ - 4+ hearts, minimum hand.

2♠ - 6+ spades, minimum hand.

2NT - a good 16-18 HCP balanced (possibly a bad 19 HCP, if such a thing exists).

3♣ - Game Forcing one or two suited hand (2nd suit not specified). Over responder's 3♦ relay, opener rebids:

------3♥ - 5+ spades, 4+ hearts, game forcing, willing to play 3NT.

------3♠ - 5+ spades, 4+ clubs, game forcing, willing to play 3NT.

------3NT - 5+ spades, 4+ diamonds, game forcing, but responder can pass 3NT.

------4♣ - 5+ spades, 4+ clubs, game forcing. Not willing to play 3NT.

------4♦ - 5+ spades, 4+ diamonds, game forcing. Not willing to play 3NT.

------4♥ - 5+ spades, 5+ hearts.

------4♠ - One suited hand.

3♦ - 5+ spades, 5+ diamonds, invitational values, not forcing.

3♥ - 5+ spades, 5+ hearts, invitational values, not forcing.

3♠ - 6+ spades, invitational values, not forcing.

3NT - Solid 6+ spades.

etc.

 

The only 5-5 invitational hand that cannot be shown directly in this structure is 5-5 in the blacks.

 

So, on the original hand, opener can rebid 3♥ and turn over the final decision to responder.

Hi Art:

 

You dont seem to have a bid for 5s and 4h and around 14-15 or more but less than gf?

 

 

2h is less(10-13) and 3c or 3h is more.

No, 2♥ shows 5+ spades and 4+ hearts and less than a game force. Typically 11-16. Perhaps I should not have used the term "minimum hand" and instead stated "less than game forcing values."

 

This is a standard rebid, the same that anyone else would make. The point is that if playing that 3♥ shows 5-5 and invitational values, responder knows that opener cannot have that hand when opener rebids 2♥. Either opener will not have 5+ hearts or opener will have less values than the 3♥ rebid would show (or both).

 

The rebid scheme shown in my previous post came from an article in The Bridge World some years ago. The method includes rebids over 1♥ - 1NT as well, where a 2♠ rebid shows the strong hands (as well as invitational hands with hearts and spades). Over 1♥ - 1NT, one can show invitational 2 suiters in all combinations, as both the 3♣ rebid and the 3♦ rebids show 5-5 invitational nonforcing hands, and a two suiter with hearts and spades is one of the various types of hands shown through the 2♠ rebid.

ok I thought so, I just would not say 2h promises a minimum hand.

[aguahombre]

Partner knows the wide range of the 2H rebid. It was also explored in a recent ACBL Bulletin. Responder raises with less and a heart fit, than on other auctions. If she rebids anything else and we have this hand, we will bid again in hearts ourselves. Not really a problem.

 

With 2-3 in the majors and weakness, pard will pref to 2S and we still rebid 3H. Only with 1-3 and weakness will partner pass 2H, and that is fine as well.

What does partner do with 1-3 and reasonable strength, say 7-9?

I would still bid 2s, not perfect but the opp are silent.

 

 

Pard may have 6s\

 

pard may have big hand.

 

we will be worse off if pard is 55 and minimum.

[aguahombre]

With the 1-3 hands of concern, responder will have already decided what to do after the expected 2H rebid. Jumping to 3H by opener won't help anything in that case, and will most likey get us to a poor 4H contract when responder is on the weak side.

No, 2♥ shows 5+ spades and 4+ hearts and less than a game force. Typically 11-18.

FYP.

accurately fixed.
