I don't know if it works with the Diagram package; I use Plain TeX (and with DVI output format) and not LaTeX, but I did write a chess macro package (with many options that may be suitable for use with some chess variants too) for Plain TeX which uses my font by default.
I do not know which fonts are used and how much, nor do I know how to contact Marroquin.
