The Ramones were famous because like me, not only could they not sing well, but they also couldn't play well. Here's the Blitzkrieg Bop.
I started practising tonight and got up to board 7. After surreptitiously seducing East to bid 4♥,
my colleague the North robot slides out the ♦J
and West covers with the ♦Q, and I slip out the ♦K.
What must West do to snatch victory from the jaws of defeat?

Here's what happened when I played it.

I'd be grateful for expert comment, I think I found the answer on page 351 of The Rodwell Files.

What is required is not going to happen very often. Because drawing the trumps removes the side late entry from dummy you have to play the diamonds in weird but not unreasonable fashion.

J-Q-K-8 if you don't unblock, N covers the second one and you can't get back to dummy to cash the 4th one if you draw trumps, if you don't, if you play a diamond, S can ruff, a spade can be played across and another diamond led and ruffed for a trump promotion.

Win the second diamond with the 7, and play 3 rounds of trumps endplaying S.

S now has to give you a trick in one of the blacks, in due course you will pitch a loser in the other black suit by hooking the diamond.
