Begging never works,,I suggest you just write an acceptance speech as if you are the winner..then Publish it here over and over and with luck (Sumi) will "assume" she picked you to win and forget...then announce (again) you as the winner...
Using this technique is foolproof,
@Blooie taught me it... I won an all expense paid trip to Australia with first class airfare and everything. I am expecting the tickets in the mail any day now along with $50,000 in spending cash for the trip...
Thank you all for picking me to win the trip, btw...
Good luck on your win..
