Excellent, thank you! Are there any more exercises to train for smothered mate?
Smothered Mate Pattern

Hey sorry, I'm not sure if other content will be added because this isn't really a real group and I've only started it privately with a friend so she can use the puzzles as reference. It's not even supposed to be publicly view-able so I'm not sure how you were able to find these.
Anyway, some of these examples aren't really smothered mates but rather just slightly similar.
