Playing MP in an instant tournament, I was hunting a top and found it with this deal. I believe the lead of any other card by East would have defeated the slam. How did I get here? Although I correctly assumed North's Blackwood response (which shows an even number of keycards and a void) meant he was void in clubs. I failed to think long enough about the possibility of 'zero' being an even number.
