Is this a Pin? or a Skewer? What is this called really?

What is this position called? It isn't a pin or a skewer because the Knight is equal in value to the Bishop, so what is this? Thanks

I'd say neither.  Just a couple of hanging pieces.

So...I'm still confused. I know it isn't a pin or a skewer, but I'm not sure what it is called.

It's definitely not a pin, because either the knight or the bishop can move freely.  It's not a skewer either, since a bishop and a knight are of equal value. 

It is exactly that

That doesn't mean it's not a pin. A pin can be absolute, a piece pinned to the king, or relative, pinned to another piece, or I guess potentially a square. In a relative pin, the pinned piece is usually considered the less valuable one.

Post 9 has it right. Both pieces can save themselves in this position with black to move. Bc3+ or Bg3+ and then save the knight.

A pin is when a low valued piece is under attack but will expose a higher valued piece if moved.

A skewer is when a high valued piece is under attack but will expose a lower valued piece if moved.

This position is just two pieces being attacked. Maybe it could be called an x-ray attack but it isn't properly a pin or skewer.

I agree with Gomer, if anything, it's an x-ray attack on the knight. Tactically, as others have noted, the attack is defeated by checking with the bishop.

We will call it a kebab.

Maybe a cannonade. It's a brand of lemonade. In a tin, of course.

So it's a x-ray attack?

Give up on Chess

Is this a name all the tactical motifs challenge or something?

Interesting comments. Does anyone have an opinion on whether this is a win, loss or draw for white. Also everyone seems to assume it is black to move. If it is white to move then it is a straight taking of an unprotected piece where white takes the bishop (maybe called miss-coordinated pieces), then a double attack on the knight and king, then when the knight interposes, it is a pin. 

It looks like it is both a pin and a skewer.

For white to move then it is just a free piece 

This.

It is an ineffective skewer, also known as a kebab. You can look it up in Gioachino Greco's Glossary of Chess Terms (1626). Unfortunately, all copies of this classic text have disappeared. Consequently, chess masters have spent centuries trying to relearn what Greco once knew. Happily, Greco has been reincarnated with the name of Hikaru Nakamura.
