Chris,
From what I understand Motley, Stripe, and Bloodred do NOT have checkering on their bellies. They can, and will, develop color or peppering. Checkering of course would consist of significant black/gray/colored squares like a checker board. Coloring of the belly will consist of a colored wash (usually orange, yellow or red in my limited experience) that slowly seeps into the belly area as the snake ages. It usually comes from the tail upwards, and sides 'downwards', from what I have seen. Peppering means exactly what it's named after, as I'm sure you're aware, just shake some pepper down on the counter and that's what the coloring will develop into over time. Someone can correct me if I'm wrong, but I also believe that as hatchlings, the belly is typically pristine white and the peppering and/or coloration develops over time. Checkering is there from the beginning.
Now, if you want to talk about hets, that's where you'll find some partial checkering some of the time with some hets . . . and non-hets as well! Usually a 'clear' stripe down the center of the checkers. Seen most often with bloodred hets.
As to the original posters snake, dorsally it looks as if it could be a motley. I've seen less motley-ed motleys pictured before! Ventrally, checkers can be difficult to see in snows and blizzards. :shrugs:
Hope that helps . . .? I'll see if I have some decent belly pics on my computer . . .
