The old beached whale technique, eh? : ) Did you find the elusive "chipped hold"?

Hi Pete, Yes, I spotted it just as I was pressing out the top. So, for some unknown reason, I decided to drop back down, onto the chip, and quickly discovered that it wasn't the best way to go; as this picture illustrates quite nicely.
Hope you're going well; give us a shout if you're over this way :)

That's how I finished it. Grovelling over thre top!
