I admit to being somewhat dyslexic and occasionally GUI challenged -- and I
couldn't find anything like this. Could you please give me a more direct
link.

I went in PS and looked one of the actions makes only grids not checks
The other one required a lot of tweaking
BUT
here is the simplest way to do what you want:

FILE new
use the resolution you need for the final finished piece
for size of checks (for 200x200 size pixel checks) I used image size 400x400px
make sure snap to guides is on
set rulers to your choice pixels or inches
set one guide at the half in both directions
get the marquee tool
make a selection on the upper right
EDIT>FILL with black
shift (or is it contrl?) click then drag a duplicate shape to the bottom right
then make a new layer fill with white drag under black check layers
EDIT define pattern

whatever document or shape you want to fill with the checks
select all or select what you want to checker
edit>fill>pattern>choose it




this will let you create a pixel-perfect grid that you can style however you need, and resize the grid without quality loss:

1 create a new image, any size (I used 12x12 pixels)
2 set grid to be 1 every pixel, activate it (CTRL + ")
3 toggle snap on as said previously (VIEW > Snap all)
4 select rectangle tool (U)
5 drag a box to fill square (A black shape now fills the image— but you may have to adjust the shape with the transform tool (CTRL + T) until the canvas is filled with solid black, leaving no fuzzy areas, and the rectangle's lines aren't off of the image area. You'll feel the cursor snag when it snaps to the document's bounds)
6 resize canvas
A: check relative and enter the current dimensions of the image (effectively quadrupling the size)
B: set the anchor to be in the bottom left corner
7 duplicate the rectangle by alt-dragging to the upper-right corner (again the rectangle will snag when it snaps into place in the upper right corner)
8 link the two rectangle shapes in the layer palette
9 create a set from the two rectangles.
10 duplicate the rectangles' layer set
11 with the second set selected, Edit > Transform > Flip horizontal
12 Select colors to fill in your grid (the current screen will be filled with black, just click on the layer palette preview icons of each rectangle, and experiment)
13 delete the background layer, and check for transparency "bleeding through"

sorry about the long post, but it really doesn't take long to do.

p.s. Keeping SNAP set to track document bounds is rarely useful, IMHO. But having SNAP on for document bounds is crucial for this piece.
