What happens when a player chooses to “plunder” in PlunderChess®?

Rule #3:  Upon a capture and when plundering is elected (yes, plundering is optional, more on that later), a "color-coded vest" that corresponds to the moving capabilities being plundered from the captured piece, gets coupled to the chess piece that made the kill. This newly acquired vest, visible to both players, displays the pieces extra moving capabilities for one future move only.

NOTE: If you are playing PlunderChess® via game app on your iOS or Android mobile device, this plundering benefit is illustrated by the overlaying of a color-coded banner (called "vests") on the piece that makes the capture. The color of the vest acquired corresponds to the powers it just plundered from the captured piece.  Vest colors are; green for pawn vest, blue for bishop vest, orange for knight vest, red for rook vest and yellow for queen vest.  Each vest, in addition to being color-coded, is labeled according to its powers.

The above board shows a black Knight wearing a yellow Queen vest (KnightQueen or NQ) on c6… and… checkmate delivered by a black Bishop wearing an orange Knight vest (BishopKnight or BN) on h3.
