MP, best hand south, Instant, pro GIB 30.

5H is a good sac v 4D, provided that they don't double and find the Spade ruff.

4H makes provided that they don't find the Spade ruff at trick 1 or 2.

In an earlier version of GIB when the original tourney was played, most of the room was in 4H by North, who responded 4H to South's Double. The Spade ruff was not found, and 4H rolled in.

To be fair to my North, I was v. min for my X, and yet 5H had chances. Not great chances, but chances.

So, in upgrading GIB, is it right that North should value the hand as worth pushing to 5?

I really don't know the answer to this. Not a bug report, therefore, just asking for opinion.


Incidentally, I think that failure to find the Spade ruff is a serious misdefence. On the bidding, West should expect a spade to be ruffed. About the only time that it costs is if declarer has AQ tight, and that is not going to be.


As an aside, if South passes 4D, should North bid 4H?

Minor quibble, a spade lead also costs if South changes a spade for one of East's clubs (East becoming endplayed when thrown in with the third club). As for whether North is worth forcing to the 5 level, I think it's close, but would settle for 4H. I don't want to hang partner for making a double under pressure.

Out of interest, would you read DK at trick 1 a signal for Spade, or just indicating a sequence? Obv would need to be human.

I prefer to play the DJ to signal spades, while the DK would be sequence showing. I prefer the K and Q to show sequences since it helps place the points better, but I'm very rarely going to be jack high in an auction like that.

A similar hand with cuebid 5 for passed player:



According to both of my hand and your hand,we can draw a conclusion:
This cue depends on GCC
- For unpassed hand,cuebid at five level,it shows 11+ total points,merely.
- For passed hand,it shows 3-12 total points.obviously it is unreasonable sometimes --- it let partner guess randomly at a too wide range.

Gib has 8 loser hand with clear preference for . Partner is allowed to assume you have about 8 pts when competing over pre-empts. So, no I would not cuebid not even close imo. If I were to make a strong bid (with a better hand but same shape it would be 5.

One of the cuebids was opposite a 2 opener and the other was opposite a takeout double (albeit at a high level). You cannot compare the strength requirements of the two simply based on whether or not the cuebidder was a passed hand.

I would not cue bid. You expect to make 4H but this is not a slam try hand.

On Lycier's hand I disagree with the double of 4D. Pass shows this hand. Of course, I don't believe that GIB has been programmed to play that partner's 2C opener creates a forcing situation - a major flaw. Still the cuebid is a bit much, and the follow-up pass of 5H is utterly abysmal.
