I see a strong resemblance to a young Lampropeltis getula goini though I've never seen one with that much red.. I don't really keep up with king snake morphs but I'll guess its some sort of flame/hypo type brooksi morph crossed into a high red goini line.
It's in the goini complex, but I don't know enough about them to narrow it any further than that. They are in general robust snakes with great personalities that colour up as they mature.
I may not be very smart, but what if I am?
