Looking at these N/S hands, it seems obvious to get to grand, yet they did not get there.  They were a multiple National Champion and a multiple World Champion who have partnered one another for years. 

Should they have reached grand? 

How should they have reached it? 

Where did the auction go wrong? 

Is N or S responsible for the failure to reach grand?

Or is there  no fault to be found? 

Would you and your partner have gotten there?

The other table reached the grand after the same 1♠ opening bid.

I look forward to your comments and anticipate a lively discussion.
