When I tried the Intersect (Boolean) to make the notch for the Bishop it didn’t cut through the Bishop instead it made a face.

Is there any question there?
General Q&A note
Help us all to help you.
Please give full screenshots with any questions. With the relevant panels open.
Also, include the lecture time and name/number that is relevant to the problem/issue.
This can be done by Blender itself, via the ‘Window’ menu bar top left hand side.
On that menu drop down is ‘save screenshot’.
Close ups additionally where they help.

Did you made a special notch?
I followed lecture 78. Boolean Modifier and 79. Boolean In Edit Mode and did every step but instead of cutting through it made a face. I also did the modifier but it also didn’t work and cant figure out how to make the notch.

See note NP5, screen dumps.
Oh I figured it out for the Modifier I forgot to add the notch

This is something that happens to me quite often. There are several reasons this may happen. See the list below:
It could be that the normals are facing the wrong direction. To check this, go the overlays tab at the top right corner. If either object is red, the normals are facing the wrong way (see below).
To fix this, go to edit mode, select all, then press “shift + n.” Sometimes, at least for me, it still won’t change the direction of the normals, so if it doesn’t work press “ctrl + shift + n” and it will recalculate the normals. The normals will should always be blue.
Another reason the booleans may not be working is that you may have duplicate vertices occupying the same space. To check for this, go to edit mode, select your object with vertices (not faces or edges), and press “m” on the keyboard. This will show a menu that will allow you to merge vertices. Select “By Distance” and it will merge any vertices in the same place. Near the bottom of the screen it will tell you how many vertices were merged (see below).
Yet another reason booleans may error is if two edges are aligned together in the same spot. It doesn’t always error, but sometimes it will (see below).
The same goes for faces. Notice in the picture above the faces on the side are intersecting as well. Using booleans in these cases will make both objects disappear. To fix this, move the edge or the object away from these spots.
Lastly, make sure to apply the scale. This can also affect the results.
I hope this helps. If the problems persists or if you have anymore questions let me know, I’d be happy to answer them as soon as I can.

Thank you for the help the Intersect Boolean worked. It was because my normals were facing the wrong way.
