That very close to the final position in Spielmann -- Rubinstein that I went through with one of my students yesterday.
probally forgot to castle and white snuk in with the queen capshuring a piece real cute.

Sorry guys, hadn't seen your replies. Here's the game in full if anyone's still interested in how the position was arrived at!
That is very Interesting

That's like gossiping behind someone's back instead of saying it to their face. In soccer that would be called offside and illegal. Definitely a unique mate !!!

I've seen that kind of mate before. It's a variation of a corridor mate. A corridor mate is essentially a backrank mate that can also be delivered along a file as well as a rank. I've found two variations of it and given them my own names: "glassy corridor mate" and "piecy corridor mate." A glassy corridor mate is where there is an opening in the corridor but that escape square is covered by an opponent's unit, so it's like a corridor with a glass wall. A piecy corridor mate is where the walls of the corridor are partly from pieces rather than pawns. Mostly commonly it happens on the back rank with rooks forming the corridor walls, as in your example. The two types can be mixed. I would therefore categorize the above mate as a piecy corridor mate. If anybody's particularly interested I'll look up and post some examples of what I mean. Thanks for bringing up this topic, though: it's a useful one for players who solve a lot of chess puzzles and need some more general mating patterns to watch for.
Thought I'd share this from a recent blitz game. The mate with the queen and rook isn't unusual, but I thought the end position looked kind of funky with the King trapped behind his big guns all completely helpless as the queen sneaks in!
