Obviously the topic description is an exaggeration

I was South in this game. The question is, do you think you could have reached 7♦? If so, how?

---

I deliberately didn't include North's response, because it was a CPU in my game. Suffice to say that the final contract was 5♦, which I thought was an aggressive gamble, but in retrospect was actually too conservative!

I can't imagine being allowed to play in 7♦; surely opponents will sacrifice in 7♥!

Actually, I can't imagine being allowed to play any contract at any level here. The question is how high you figure you can safely push the opponents.

Who was playing a CPU - your side?

Only North was a CPU I believe, so my side.

Hmm, I hadn't thought about the possibility of a sacrifice, but it didn't happen in my game. 7♥ doubled -3 is 600 points, which is substantially less than what a grand slam makes. Still, one can hope

Oh, you mean CPU, a bot, not CPU, a concealed partnership understanding. Sorry.

Wow, I wasn't even aware that acronym existed. Thanks for letting me know!

Well, it's 800, but still a good sac.

Although NS could bid the perfectly reasonable but doomed 7♠ over 7♥.

1♦-(4♥)-5♥- seems the obvious start, but it's then more judgment rather than system.

Well, the preempt worked enough to probably stop you from reaching 7. There's just no way to identify that all the cards are present for 13 tricks to be made.

Nonetheless, the North hand has a 1st round ♥ control and fits for whatever South bids next. Even better, North has controls and honor combinations in every suit beside ♥s. So, the hand is well worth a 5 ♥ bid. 5 ♥ should show the 1st round ♥ control, imply a fit in ♦, and show a really good hand because the bid is driving the partnership to slam.

After 5 ♥, South should bid 6 ♦, if possible.

I don't know - can't South try 6C? Duplicate shortage is bad, yes, but South's hand is otherwise good; someone has to have the spades, and it's likely to be North holding the KQ if he bids 5H. After 6C, North very well might bid the grand next. And if he does it by jumping up direct to 7D, West might not take the sac, on the off chance that opps have guessed wrong.

Then 5♠-5NT-7♦ seems possible if the opps don't bid any more.

Yes, I suppose it is an exaggeration - the evidence linking preemptive bidding and global warming is controversial, even if the others are not....
