  (1) Posted by Administrator [Saturday, Feb 25, 2012 04:49]  Help needed with Locusts! Can anybody teach me, and give the example(s), about the KnightLocust and PawnLocust (and also the related marine pieces Squid and Prawn)??
Thank you!   (2) Posted by Kevin Begley [Saturday, Feb 25, 2012 07:41]; edited by Kevin Begley [120225]  >"KnightLocust and PawnLocust (and also the related marine pieces Squid and Prawn)??"
The Fairy Kings article defines:
Squid: moves like a Knight and captures like a KnightLocust.
Prawn: moves like a Pawn and captures diagonally like a PawnLocust.
Unfortunately, it does not define a KnightLocust or PawnLocust.
My semieducated guess is:
KnightLocust is PROBABLY like a Knighthopper, except it must arrive on an empty square, and it must capture the hurdle (hurdling friendly units is illegal).
Note: a Knighthopper is like a Nightriderhopper, except it is not a rider.
Thus, a KnightLocust from a1 may hurdle (and capture the hurdle on) b3/c2, and arrive on empty square c5/e3.
But, unlike a NightriderLocust, it may not  again, from a1  hurdle something on c5/e3 (even if d7/g4 are unoccupied).
A PawnLocust might similarly move like a Pawnhopper, except, again, it must arrive on an empty square, and capture the hurdle.
A Pawnhopper moves like a pawn, but both moves (only forwards) and captures (only diagonally) by hurdling.
Thus, a white PawnLocust from f3 PROBABLY can hurdle (without capturing the hurdle) some unit on f4, arriving onto an empty f5.
Or it might hurdle (capturing the hurdle) some unit on e4/g4, arriving onto an empty d5/h5.
Even if my guesses are correct, it is highly unclear to me whether a PawnLocust can legally forward hurdle (w/o capturing the hurdle) over a friendly unit.
That's my best guess... but, I find no problems using these fairy units (even by another name).   (3) Posted by Kevin Begley [Saturday, Feb 25, 2012 08:04]; edited by Kevin Begley [120225]  I was thinking these might also refer to Knight and Pawnunits, from the marinefamily, in some specific variant chess game.
And, I managed to find a possible explanation: https://chessvariants.org/~chessvar/index/msdisplay.php?itemid=MSmanandbeast12:
It covers squids and prawns (from which you can infer the meaning of the other units, based upon the definition provided in the fairy King's article).
However, be warned: this site does not exactly provide concise definitions.
According to the site:
"Snail+Shrimp=PRAWN" and "Snail+Lobster+Shrimp=SQUID"
So, what is a Snail, Lobster, and Shrimp?
I'm glad you asked that... the simplest answer I can gather (assuming the mathematical operators function normally) would be: "Snail = Trilobite  Lobster"
And, what in the deep, deep sea is a Trilobite?
Clearly, the answer is: "...an extinct marine invertebrate whose left, right, and central lobes (hence the name) fit with 3 (in 2d) forward leaps..."
Duh. Of course! SeaCucumber takes Abalone at DaveyJones3, checkmate.   (4) Posted by Joost de Heer [Monday, Feb 27, 2012 00:42]; edited by Joost de Heer [120227]  Some examples of the marine knight and the marine pawn:

Joost's examples helped me to search the WinChloe in different way and I found a few dozens more problems quering for 'Cavalier marin' and 'Pion marin'  should have got this idea myself, but the fact that other marine pieces are there with their 'real' names (Poséidon, Sirène, Triton, Néréïde) has misled me.
So the definitions are:
Squid: moves like a Knight and captures like a KnightLocust
Prawn: moves like a Pawn and captures diagonally like a PawnLocust
Now, knowing what I should search for, I found the competent answer at Christian Poisson' site:
"Equilocusauteur(m,n)  (m,n)Equilocuhopper
Piece moving like a (m,n)Leaper until it reaches a square occupied by a unit which can be captured: the hurdle. Then, from the hurdle, without changing direction, it makes a (m,n)Leaper leap on a square which must be unoccupied. The unit on the hurdle is captured."
(http://christian.poisson.free.fr/problemesis/categories.html#Equilocusauteur)
Definitions for KnightLocust and PawnLocust can be simply deduced from this.   No more posts
