3) LAMING: To 'lame' a piece (to take - and permanently remove from play), it must be surrounded on any three of the eight squares adjacent to it (i.e. touching at the sides or corners - (see fig. 3). Accordingly, the attacking player will have fewer positional options, if laming a piece which is in a corner, or next to the edge of the board.

Light (or Dark) may remove their opponent's piece by surrounding it on ANY THREE of the eight squares adjacent to it (see example above)

Players MAY NOT 'lame' their opponent DIAGONALLY across the centre diamond, before the bladder has been picked up. (see example above)
Pieces may not be lamed diagonally (across) the centre diamond, until the bladder has been picked up (see fig. 4).
Only one piece may be lamed per move. Laming the bladder carrier, automatically transfers possession of the bladder to any of the three attacking pieces (player chooses). Once a piece has been surrounded by three attacking pieces, there is no defence - and their piece is permanently removed from the game.
3a: Players may move a piece into a position where it is surrounded by three of their opponent's pieces, without it automatically being lamed (i.e. passive laming is not allowed). To lame the piece, the opponent must move one of his three attackers (or another nearby piece) to create a new (or altered) three-on-one configuration (i.e. only aggressive laming is allowed).
