I think the unique six is very neat. I'll look for it in future.

Keith, following your clues, one finned x-wing on 3 and another on 4 eliminated both from R2C5 and the puzzle collapsed.

After you have entered all of the "obvious " numbers, you deduce, by eliminat ...

Done it! The 2/4/5 xy-wing eliminates 4 in r1c3, which makes it a 9. The rest is straightforward.

Thanks for your response, Keith. I'll have to work on this as I've never used xy-wings.
