With the 1 opening and 1 overcall how would you get to the grandslam? I doubt I can bid 7 over partners 5 bid (I was thinking he had more like 7 solid trump). I was hoping my 3 bid was something like "tell me more partner", 3NT being a stopper of some kind (not expected with e's holding) or maybe 4 with honour doubleton, is this correct?? Anyway I wasn't quite expecting 13 tricks off the top (more like 7 trump and 5 outside), what do you think? Also what would be the difference in meaning between a 4 bid and partner's 5 bid?

To me, 5 is a lot of clubs, 4 isn't quite so many.

From E's point of view, partner must have a side card outside the club suit or he'd have opened 3/4/5 (would an opening 4 have been natural or NAMYATS style ?) and it could easily be a 3 card major suit holding (wouldn't you preempt 1138 say). A singleton heart could easily be all you need to ruff out the suit.

From W's PoV, I'd read 3 as either "I stop the spades but not the diamonds and am looking for 3N" or a club raise. I would have bid 4 over 3 saying "I don't stop the diamonds but do control them, and have enough clubs to be confident here", now it continues 4(cue)-5(void, no spade control)-5(spade control no K)-5N(which in style for us says "I have something I haven't yet been able to show" which will be K or Q which should be enough for the grand to be bid.

Would not open 1

I would start with a high level preempt and would not get to the grand because we wouldn't be able to place the Queen of Spades

If you open 5 partner won't bid 7 as you could easily have xx, xx, x, AKJ10xxxx where it's no play.

1 followed by 5 and partner will assume something outside and probably bid it.

I fully grant bidding 7c is a bit of a guess, I like that long h suit and lots of entries.

PRefer 1c then 5c to be more outside but that may be old fashion. Sort of a 3 loser hand with few hcp.

I would 100% bid 7c after 1c then 5c :)

I would not have followed the same bidding pattern, but why not 4 after partner's 3? There's no way he will pass, and in this situation it communicates what partner needed to know.

Hi,

the problem with 3S is, that there is not much room between 3S and 3NT, but
given that 3C does not necesarrily show 6+, it is hard to come up with a good
alternative to 3S.
Seeing both hands a neg. X may have worked better, but having a forcing 2H bid
av. and a 6 card suit, 2H is obvious.

The way the auction went, you did well to reach 6C.

You may reach 7C, after a 5C opening bid, but a 1C opening bid is not wrong.

With kind regards
Marlowe

I was wondering about this too - what would everyone think Responder was showing if they used a double-cue-heart sequence? For example 1 - (1) - X; 2 - 2; 3 - 3.

Aside from the theoretical, I think worrying about system for hands with an 8PT opener that is being shown as a minimum opposite a SJS Responder should probably not be a high priority - I am fairly sure the OP's system has more important system holes. As a further aside, I am not fond of the 1 overcall - 2 or some 2-suited jump seem to make life much more interesting for E-W.

I prefer a 5 opening preempt.
But whether it starts with a preempt or the way the auction presented started, I think getting to a Grand is tough.

On the given auction, after 5, E will be counting tricks. A reasonable assumption is that W has AKxxxxx and an outside high card. But that's only 12 tricks. A 13th could come from finding Kxx in diamonds or setting up the H suit. But you could just as easily have an unavoidable H loser, like xx xx Kx AKJxxxx. Too much of a guess to bid the Grand. And if you back up the auction more, second guessing E's reasonable 3 bid seems like "resulting" it to me.

I think west is too good for 3, whether you play it as forcing or not (I think non-forcing is standard). I would rebid 4. East could essentially raise that directly to 7 with his monster, with whatever science along the way you feel like.
Please let me know about any questions or interest or bug reports about GIB.

1C is clear for me at these colours.

I'm also happy with 3C. The 8c suit is huge, but holding minimum high cards and Qxx I'm happy to take a conservative position. 3C also leaves the most room for partner to describe their hand.

5C is a reasonable choice if it shows extra distribution and club length - basically a 5C opening with a bit outside. I'm also assuming that 4C would've been N/F.

Over 5C East, can tell that grand-slam must be a huge chance. Even a sub-minimum hand with a singleton heart such as [xx x xxx AKJxxxx] makes the grand 80%+. Almost any full strength hand should make it lay down.

If I wasn't confident with my agreements at that point i'd be happy to just blast 7C. Not investigating grand-slam at all is definitely a mistake.

I too think 4 should be a better bidding partner following with 4NT(=RKCB 3014-club trump), 5NT(=2 keys+void). It has to consider that with 5 (presumibly) entries in dummy we can get grand easyly.(Lovera)

Seems like once we learned Opener has all those clubs and didn't open 5C, we should just bid the darn grand.

..It are examples that justify this opening : - 2 KJ98 KQJ98742 , Q83 4 - AK10987654 , - - KQJ87542 QJ1032 , Q763 - 2 AQJ108642.. [9 or 10 tricks principally from longness] (From "Il libro completo del bridge di gara by Guido Barbone pagg. 53-54 Open bidding of five in a minor suit).
