I really can't complain about the result here because it was my mistake to push into a spade slam instead of the much easier club slam. Yet the play at trick 9 here is remarkable. All set up for a trump coup, but then inexplicably plays low from dummy. I'm too big to cry, but it hurts too much to laugh.

No coup available at trick 9 South has no spades at that point so West has easy exits e.g. Q and North has clubs still so no overruff possible. - you are guaranteed down but that club plays gives one more down- thanks for putting the boot in GIB.

At trick 9, just keep playing top clubs. When West ruffs, you can then ruff the next trick and draw the remaining trump. I meant 100% line at the point of finding the 4-1 break btw. Alternatively, just cash the K before running the clubs.

 

Yeah, I didn't understand the club duck...That seemed to be the "misere" bridge play.

Perhaps some use a different definition of trump coup than others. The line to make is as manudude describes, and at least by one definition constitutes a trump coup, permitting declarer to take advantage of his trump tenace over West's holding despite having no trumps to lead from dummy.
