Board Notation
aka. English Notation

Moves are recorded from the viewpoint of the player making them, so that each square has two descriptions (eg. for the Queen's Bishop's file, White's QB4 is Black's QB5). The squares are denoted only in uppercase lettering. Used in older English-language chess books and still favoured by many leading players as being less abstract than the Algebraic.

Nowadays the terms Kt, QKt, KKt are often replaced by N, QN, KN (though this guide retains KKt etc throughout all single-move pages to avoid confusion).
