Not all that new - it occurs twice in ChessBase's Mega database.

The mirror position (black queen on d1, black pawns on d4 & d5, white king on d3) also occurs twice

It might not be new (almost everything in that can happen in chess has happened at some point by now) but id certainly say it is a rare and novel way to deliver a mate which will be new to a lot of people.

Any chance of posting one the games?

Interesting because doubled pawns are rarely as useful as that. So positional weakness acting as tactical strength.

You get similar patterns if you replace the distant pawn (the one not next to the king) with the opposing king, and again if you remove the distant pawn and add a knight one square behind it.
Any chance of someone posting those mating patterns and seeing how often they are to be found in a suitable database?

Or if you replace the doubled pawns with bishops

That's a really excellent finish to that game, Geoff. If Black didn't have 30. ... Rh3+ it would have gone the other way. The game from the under 1200 tournament was interesting in its way too, but the mating pattern was just a coindidence in that one. It could have finished in a number of ways.
