-h3 Basics
+p.boxed.
+ Each capture results in an "explosion" through which all surrounding
+ pieces other than pawns are removed from the board.
p.
- When a piece captures an opponent figure on some square S, all pieces sitting
- on a square reachable by a king move from S are removed.
+ When a piece P captures an opponent figure on some square S, all pieces
+ sitting on a square reachable by a king move from S are removed, including P
+ itself.
The pawns, however, remain: they have to be taken directly to disappear.
+p.
+ Suicide is forbidden. Thus a king can touch the opponent king and become
+ immune to checks, like on the following diagrams: 1.Rxf5 is impossible.
