What do you call this mate with bishop and knight?


Not sure that one has an individual name. It's not one of the usual Model Mate patterns (Damiano, Lolli, Anderssen, Morphy, Paulsen, Epaulettte, etc).

There are quite a few of those Knight-and-Bishop mates that lack a specific name. Here's another... carried out in this case by Knight and Queen, but only the Queen's diagonal ability is used in the mating pattern, so it might as well be a Knight-and-Bishop mate.

I believe I'm familiar with all the mates that have names, and more that I've given names, and I've never seen a name for this type. How about inventing a name for us? (I'm serious.)

Anastasia mate, death cage mate, chili potato mate, check in your face mate, ziggy zug mate, bump mate.
There are a lot, this is different tho, just anme it however your interior poopfeels like.

"The Horse Whip"?

It looks like a name for this type of mate already exists, per a thread on this site just one day later: semi-smothered mate. Sorry, I'd never heard of that one before!

BTW, that position I gave above (post #3 ITT) is a rare example of a Pawn being pinned against an empty square instead of the more common pin against a major piece. White's Queen on h6 pins the Black g-Pawn against the (empty) mating square f6... which allows White's Rh5 move, forcing mate.

Thanks Sqod... I still prefer "The Horse Whip" though :-) Blueemu, your comment confirms my earlier feeling that your example was a rather more sophisticated trap than the one in my game. My opponent ought to have seen it coming...

Nice trap, though. As Black I wouldn't have played ...Nxd4 in the Scotch anyway, but this line punishes it severely and it's far from obvious that Nd5! is going to cause Black so many problems (and that therefore ...h6 was basically unplayable). Well done!
