We use our own notation, which coincides with FIDE notation KDTLSP for orthodox pieces, and with popeye English notation for fairy pieces, when it doesn’t confict with FIDE. In rare cases when it does (notable “L” for locust) we use alternative piece designation, always two letters. The current list is viewable on site.
A handle is a short identifier for a person. Handles are given to people automatically when they register on site, or may be already there for those mentioned as authors in the existing problems.
It has the format “LLxF”, where “LL” is two first romanized letters of last name, “F” is romanized first initial (normally, first name). “x” is a random number, for vast majority of people it’s a single digit. For example, handle for Imants Dulbergs is “DU2I”. Letters in handles are always in upper case.
Handles were introduced to circumvent constant confusion with different spelling of the same name, and are used pervasively around the site for identification. Handles are designed to be human usable and easy to remember. Yours, KE2I.
You might have heard of FEN, used for a long time as a compact way to record a position. In problem “show” page you see FEN and FEF strings. FEF is an in-house format, developed to be compact enough to be used in URLs, and differing from FEN in one detail: it can record fairy pieces, all of them. Why should you care? You shouldn’t, unless you have a need to reference a diagram with fairy pieces elsewhere, in which case you may write something like http://www.ankona.ch/*FEFstring. This functionality is disabled, unless someone asks for it.
It probably is! Send me e-mail to the address at the page footer.
