♠ Q
♥ AKQ85
♦ J87643
♣ 10

1♦ 1♠
1NT???

Looks like a glitch between rebidding 1NT and 2♦.

It will be investigated for fix.

Would you want to open ♥ then rebid ♦ (maybe a couple of times)?

Having 6th minor GIB will ignore 5th major in opening and will open 1♣/♦.

Just longer suit wins when selecting.

Yes, clearly that is what GIB does. My question was to ask whether folks think this is a good idea.

If we do that, we need to come up with a precise specification of when it's appropriate. Should we base it on the quality of the suits (so that ♥Jxxxx ♦AKQxxx is opened 1♦), or do it any time we're not strong enough to reverse (keeping in mind that you don't need as strong a hand to reverse with 6-5)?

[Bbradley62]

I'd prefer the latter, but I deliberately made my posts as questions because I certainly don't know whether that would be a majority opinion.

[barmar]

When I pick up a hand like that, I'm certainly tempted to open 1♥. I'm not sure whether I'd do it, though. It might also depend on whether partner is a passed hand; if I'm in 3rd seat it's more likely we'll end up on defense, and if he's on lead I'd certainly prefer a ♥ lead than ♦.

Either would be a clear improvement. To help your staff pick one: http://www.bridgebas...age__mode__show

BTW, GIB doesn't always rebid 1NT with this shape. It will rebid 2D if the suit quality is better (twice rebiddable).

I think suit quality is not as important as shape. Therefore, if a bid shows the right shape but wrong suit quality, the other bid shows a right suit quality but wrong shape, one should choose the right shape.

My suspicion is that the rule was matchpoint-oriented. It will rebid a rebiddable major, but requires twice rebiddable minor.

I don't think it's possible to make rules take form of scoring into consideration explicitly in the bidding rules, but simulations do. However, I believe the rule being used for this bidding sequence disables simulations.

[Bbradley62]

There should almost never be simulations at the 1- or 2-level. At that stage of the auction we should still be trying to have an honest exchange of information with partner, which generally means following rules.

[barmar]

And in fact, I believe most of the early rules have simulations disallowed.
