If we use western notation for igui, then what does Lnx!4e mean?
Does it mean capture a piece that was on 4e and go back to the previous square?
Or does it mean capture a piece and end on 4e?
Move Notation
Sort:
The square indicated in the notation "Lnx!4e" is of the piece being captured.
I have recently noticed a trend in notation provided for moves. These tendencies may cause unnecessary confusion in certain cases. As such, the following is meant to clarify the stance of the CSL when interpreting such cases.
- (Western) If erroneous letters are added to a piece abbreviation, the longest acceptable abbreviation starting from the leftmost letter (including those used for square disambiguations) shall be considered the intent. Any additional letters that cannot be accounted for shall be considered a typo, but the move remains binding if legal.
Ex: "Gd" is not a valid abbreviation for "gold". Therefore, if any gold is on the D-rank, this is treated as the intended piece to be moved, even if it cannot move to the specified square while another gold could. If no gold is on the D-rank, then only the "G" is treated as intended, and any gold may move to the specified square.
Ex2: If a piece is normally referred to by one word, and its full name consists of two words, then the first letter of that second word may be added without penalty. If "SG" or "Sg" is used to refer to a silver, there is a silver on the G-rank, but it cannot move to the specified square, and the other silver can legally move to the specified square, then the move is considered valid.
Ex3: If "rB" is typed, we consider that this as a whole is not an acceptable abbreviation. Taken from the left, "r" may refer to a rook, so "rB" shall be taken to refer to a rook. - (Western) Piece abbreviations shall primarily be considered in the uppercase.
Ex: "GB" is the standard abbreviation for a go-between. If "Gb" or "gb" or "gB" is written (any lowercase letters), this may refer either to a gold on the B-rank or a go-between, whichever can legally move to the specified square. However, if both could make the move legally, then "GB" shall explicitly refer to the go-between and "Gb" shall explicitly refer to the gold. Likewise: "WH" white horse vs "Wh" whale on H-rank / "BG" bronze general vs "Bg" bishop on G-rank / "DE" drunk elephant vs "De" dragon on E-rank / "GC" golden chariot vs "Gc" gold on C-rank / "HF" horned falcon vs "Hf" horse on F-rank / "SE" soaring eagle vs "Se" silver on E-rank, "FB" free boar vs "Fb" falcon on b-rank, "FL" ferocious leopard vs "Fl" falcon on L-rank, "FK" free king vs "Fk" falcon on k-rank
Ex2: "Ph" always refers to a phoenix, since it is never necessary to refer to the rank of a pawn.
Below are listed all piece types and all their accepted abbreviations for use in rated CSL games.
Any combination of either the Japanese or Western piece abbreviations with a named square is acceptable, in any order, with an optional hyphen "-" in between. Squares are named first by the number of their file, then either a letter or number specifying the rank.
For example, these are all acceptable ways of writing the same move...
Western Notation
When 2 pieces of the same type can reach the same square, there is a problem with ambiguity. In Western notation, this is solved as in chess, either specifying the moved piece's originating file (e.g. R8-5d), or the moved piece's originating rank if just the file would be ambiguous still (e.g. Gd-7c).
If a piece has the option to promote, use either a plus sign "+" at the very end to specify promotion (e.g. VMx10d+) or an equal sign "=" at the very end to specify non-promotion (e.g. VMx10d=).
If a lion or falcon or eagle moves twice, the second part of its move is appended (e.g. Lnx4e-4f).
If there is an igui capture, you can use a shortcut by including an exclamation point after the "x" signalling a capture (e.g. Lnx!4e).
You can simply write "pass" to specify a passing move. As far as I know, there is no convention for this.
