For example, "VII" and "V" is forced by Roman Numerals needing to multiply to 35. Then, my chess puzzle was "Rf7+"
The atomic numbers - V: 23, I: 53, Rf: 104
2×23+2×53+104 adds to a number over 200, which is frustrating because it seems like there should be a trick, or it should at least be solvable
