+ | Three new pieces appear. All pieces are unique.
+
+p.
+ 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.
+ 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.
