North should've bid 4 and then 5 and then 6, south can go after that, but as it is he wasn't given that option since north could very easily be off a spade trick.

So 100% north.

He wasn't given that option? Of course south has this option, north has just shown a hand that wants to play slam by itself and south has Q10xx of diamonds plus a singleton heart.
and the result can be plotted on a graph.

I agree with Han. North has shown a red twosuiter that wants to play a small slam in a red suit, regardless of what South holds. If South trusts North, he has an easy 7 bid.

How sure are we that 4N wasn't blackwood (and 5 zero)?

Aside from this hand, what's the expert treatment of the balancing jump to 4N here? Natural slam invite or minors (with cue being OM+minor)?

I can't believe people think everything is obvious on auctions like this. No one has any good idea what anyone needs for anything. North doesn't promise 12 rock solid tricks to bid slam on his own, to some extent he has to take a chance (like he did on the actual hand!) so it's silly to say if south has some sort of sure trick he should raise to a grand (granted he does have more than that.) Whose fault would it be if south raised to a grand and north had - KQJxxx AKJxxx A? Whose fault would it be if north cuebid twice and south thought Kxxx x Qxx Qxxxx was (more than) enough to bid a grand? When they preempt you should tend to shoot low, and sometimes you will underbid like this time. It happens.
Please let me know about any questions or interest or bug reports about GIB.

agree with josh, you shouldn't be blamed for this.

But also think South is closer to bid 7 than to pass 6. Not an easy decision, but having KQ partially wasted and still making 7 sounds like he underbid a bit.

I'd rather bid 7 on 5 than 6.

All partner needs is to four small in a red suit and four spades, for a grand to be reasonable.

When I have a fair shot of making a grand facing a true Yearl, I bid it.

Of course if I have a sequence available to show such a powerhouse, I'd use it.

The question is, what does the 4 bid signify? If this is Michaels based and following Rogers auction, the 5 bid forces the contract to the 6 level with no help from South. What would a bid of 6 from South now define?

North has 3 options of moving the contract on assuming a solid suit, 5, 5NT or 6. Which ever way you chose, one of these should enable the partnership to get to 7? Would this be reaching too far for a decent partnership?
bridge is never always a game of exact, for those times it's all about percentages, partner and the opponents.

I don't bid grand slams on speculation.

While South's hand is quite good on the auction, he cannot guarantee that his hand provides the 13th trick and that North has no quick losers. So, while South may be understandably worried that his hand is going to produce a grand, he has no way of knowing it with certainly.

Preempts do work.

Agree that North has a 4 call. 6 would then describe the hand perfectly. I don't like 5 because that implies club support and might cause South to misevaluate if South has a clubs-only hand.

South still has a guess over 6 but sometimes will guess right and bid 7.

How about 3 pass pass 5 ?

If North had overcalled 6, everyone would agree that south should bid 7. This is essentially what happened so south should still bid 7. Easy
