Basic Moves in Reversi: (continued)
** An example at the start of play: D4 is occupied by a white piece, and it is adjacent to E4 and D5, providing a basis for Black player to make his move from both E4 and D5. Black player may "claim" the empty C4 square by "flipping" the white D4 from black E4. Alternatively, Black player may choose to "claim" D3 by "flipping" the white D4 from black D5.
"Flipping" multiple pieces: As the game progresses, it becomes necessary to flip more than 1 opponent piece in any round. For this to be possible, the following conditions apply:
* Playing pieces in the opposite color must occupy squares in a straight line starting with an adjacent square to the player's own piece.
* There must be a vacant square at the far end of the straight line formed by the opponent's pieces.
** As an example, refer to Diagram #1: it is the black player's turn to move. Notice that squares D2, D3, and D4 form a straight line occupied by white pieces. Since D1 is vacant, this makes D2, D3 and D4 vulnerable to flipping by the adjacent black D5. The result is Diagram #2-A, where the black player has just claimed D1 and flipped D2, D3 and D4 in so doing.
** As an alternative example, from Diagram #1: It is the black player's turn to move, and squares D4 and E5 are vulnerable to flipping because (a) they form a straight line, (b) are adjacent to the black C3, and (c) the square F6 is vacant. If black player chooses to claim F6 and flip D4 and E5, then the game board will look like Diagram #2-B.
Tips on Strategic Play for Reversi:
Territory Wars: As the match progresses, the game board starts to look like a land map with territories drawn in black and white on a field of green. It is important to note that there is no limit to the number of times a playing piece can be flipped. In fact, all squares on the game board are inherently flippable and re-flippable, except for the 4 corner squares.
Valuable Real Estate: For the reason that corner squares cannot be flipped, and edge squares may only be flipped by other edge squares, these therefore represent valuable real estate in Reversi matches. Smart players play towards claiming these squares, and best results are achieved when edge or corner squares are claimed towards the end of a game, thereby allowing the player to flip a great majority of his/her opponent's pieces in the process. |
Diagram #2-A:
Black player has just claimed D1 by flipping D2, D3 and D4.
It is now the white player's turn to move.
Diagram #2-B:
Black player has just claimed F6 by flipping D4 and E5.
It is now the white player's turn to move.
