By "M/m", do you mean 5+M 4+m, or could it be 4-5?

Did they have another way to show 5+ diamonds with a 4-card major?

I duck the first diamond, and cover the 8 with the 9. What happens?
... that would still not be conclusive proof, before someone wants to explain that to me as well as if I was a 5 year-old. - gwnn

the M/m option is 5+M/4+m, on the second diamond, North covers with the T.

This is really hard to think how to play this single dummy, because you've given us so much information about the layout. At trick one, South could have been leading from J10xx in diamonds and North could be 2=5=2=4.

Now we know the diamond layout I'm going to cover the lead, win the club return in dummy and run the D9.

I probably ruined this problem by giving too much info too early, was late at night, didn't want to stay up waiting for questions.



Teammates found the heart lead and a further declarer slip led to -2. I managed to make it (on the ♦J+8 lead). Gained 11 imps.
