This template checks whether any given input strings are valid speedy deletion (CSD) criteria. If any of the input strings are valid, the template outputs "yes"; if none of them are valid, it does not output anything. Valid CSD criteria take the form of a letter plus a number, e.g. "G6" or "A7" (see the table to the right for a list). This template accepts both uppercase and lowercase letters as valid, so both "G3" and "g3" would return "yes". It accepts any number of input strings. It is also possible to compare the input strings to a custom selection of CSD criteria.
