Ah, I didn't see the last pattern to be able to spot Qc8+ with Rf7+ so I didn't understand why the sac worked until I saw the solution.
good & easy..
Another complicated puzzle and I needed help to get going!
Harder but still easy ;)
Helpful in forcing the g/h file mate.....
Why doesn't black Qc1+ instead of hxg6?
Good puzzle - not obvious at all!
