*'''Forking''' - attacking two undefended pieces simultaneously with one piece of your own.  This forces your opponent to, essentially, choose which piece to sacrifice.  Forking between rooks is a common strategy, especially with a knight.  Forking between a rook and a king is common, too, since the player obviously cannot surrender his King!

*'''Pinning'''- this strategy involves maneuvering your piece, so that there is an enemy piece in between your piece and the enemy king. This creates a situation in where the opponent cannot move the piece in question anymore, because to do so would be to place the king in check. This strategy can be used to make taking the piece in question an easy task, or by keeping the piece in question from interfering in a future attack.

*'''Sacrificing for Position'''- This involves intentionally allowing your opponent to take a piece, in order to open up for a counter attack. By offering up the piece, the opponent may weaken his defenses by attacking it, allowing for a decisive strike.

*'''The Pickle'''-This is a special gambit in chess that may work on inexperienced players. By pushing king's pawn as your opening move. If your opponent pushes kings pawn as well (the most common response to kings pawn is to push kings pawn), then move the queen to h5 on the board. If the player is ambitious, they will most likely advance the knight's pawn to g6 to attack your queen. At that point, move the queen to take the king's pawn on e6. This will place the king in check, forcing him to block the check with a piece. Then, since he moved his knight's pawn, the path will be clear for you to capture the kings rook, effectively removing one pawn and one rook from the game by turn 7 and imbedding your queen behind his front lines.
