What is it called when a bishop attacks two pieces at the same time?

I mean like this:

That is a skewer.
If the a8 rook was on h1 it would be a fork.

It could be called a pin or a skewer depending on whether the most valuable piece was in front (skewer) or behind (pin).

Or, it could be a bishop fork.

I dunno what the position you've posted would be called.

Is it still a skewer if the pieces are of equal value?

Besides if black to move it was a pointless skewer

If you mean because black can mate in two anyway, that was just unfortunate placement of the kings in my example. 😳

According to this page it's a simple skewer....

I quite like it - I used to have a book on chess tactics where there was a chapter on each type of tactical method (pins, skewers, deflection, etc.) and at the end of the chapter there were positions where you'd have to work out how to exploit the manouvre, they also had questions where you'd get a position not unlike the one you've given and have to find the way out.
