The magic layout didn't come up in my 6C (a contract which certainly didn't deserve to make) but some got saved on this hand. Without making excuses for not winning the event by playing better ourselves I do notice that this hand, from the 2nd last match, spelled m-a-g-i-c for the other medal winners.
At our table West opened 1NT and I overcalled 2C for majors. Freddan jumped to 4H and made +650 on a club lead and cross-ruff. Our opponents got to 3NT against teammates which of course made on a club lead when the diamond suit was running.
Sjöberg-Axelsson, for the event winners (one VP ahead of us in final standings), won 11 imps for +660 (vs +150) and the 3rd placers (whom we beat on imp quotient) won 10 imps for +690 (vs +200).
Changing the diamond layout would've made at least a 5 VP difference in our favor (each table going several down in 3NT vulnerable for sizeable swings in all matches; number of VP's depending how many down).
And I would have one less story to tell.
