How is this tactic called?

Hello!

I was solving this puzzle (here's a link) and I'm not sure what's the name of this tactic:

It's black turn and the bishop moves to c6, to the same diagonal of the two queens.

Now if the white queen takes any of the two pieces, she is captured back by the other one.

Does this combination have a name?

Thank you!

It's this more or less:

Thank you! Does that tactic fall into the x-ray type because the attacked rook is the piece targeted "through" the others?

The main tactic here is the subsequent win of white's rook.  The queens are just an equal exchange.  I guess the applicable term here is simply that the rook is trapped.  I suppose you could also call it an x-ray defense of the queen.  Bc6 was a very nice move, by the way.

It defends the queen, but you could say that because of x - ray there are 2 attackers of the rook, and only one defender. But of course - trapped piece also fits the bill nicely along with x ray.

Onbviously we have what appears to be a triple corkscrew flip 180 by the white pieces here. Sheeeesh!

@Knights_of_Doom : yes, it's a nice tactic when you spot it!

That's an additional way to see it that didn't occur to me.

@Sock_Guy : I'll call it "triple corkscrew" from now on!
