-  ...Only the initial position changes, but this makes a huge difference.
-  In particular, castling would be rather pointless so it's disabled here.
-  En-passant captures are impossible because all pawns already reached 7th rank.

-h3 About the initial position
-
-p.
-  Since truly random start can allow a mate in 3 with a knight,
-  the kings have at least one knight neighbor in the initial position.
-  This allows to move free out of potential check from the very beginning.
+  There are only one rook, one bishop and one knight per side in this variant.
+  That explains the name. The king and queen are still there,
+  and the three remaining slots are taken by new pieces:
+
+ul
+  li.
+    The lancer 'L' is oriented and can only move in the direction it points,
+    by any number of squares as long as an enemy isn't met
+    (it can jump over friendly pieces). If an opponent' piece is found,
+    it can be captured. After moving you can reorient the lancer.
+  li.
+    The sentry 'S' moves like a bishop but doesn't capture directly.
+    It "pushes" enemy pieces instead, either on an empty square or on other
+    enemy pieces which are thus (self-)captured.
+  li.
+    The jailer 'J' moves like a rook but also doesn't capture.
+    It immobilizes enemy pieces which are vertically or horizontally adjacent.
 
 p.
-  A less constraining condition would be to require the two knights to stand on
-  two squares of different colors, but it's not enough as proved by the
-  following diagram.
-  White can mate in 3: 1.Nc6 followed by Nb4 threatening both a2 and d3.
+  On the following diagram the white sentry can push the black lancer to
+  capture the black pawn on b4. The lancer is then immobilized
+  by the white jailer at a4.
