Ah. chessfss = require('chessfss.lua') works in context. And it
seems to work with latex too (I had somewhere in the back of my mind
the thought that the ".lua" extension breaks with latex but can't
reproduce it currently).

The chessfss.lua has a "return Table" at the end which declares the
table chessfss.
To quote from http://lua-users.org/wiki/LuaModuleFunctionCritiqued:
"The problems above can be avoided by not using the module function
but instead defining modules in the following simple way: [*1][*2]
-- hello/world.lua
local M = {}
local function test(n) print(n) end
function M.test1() test(123) end
function M.test2() M.test1(); M.test1() end
return M
and importing modules this way:
local MT = require "hello.world"
MT.test2()"
