How to escape the Pin

Hello Everyone. A pin is a strong tactic in chess, that when used right can completely immobilize a threat. For those of you who are unaware, a Pin refers to a scenario where a piece is on the same rank or file as a more valuable piece, and so is an enemy piece capable of attacking that piece. Only Rooks, Queens, and Bishops can Pin.

In this example, the bishop is maintaining an Absolute Pin on the pawn. It cannot move because it would put their king in check. The Rook is maintaining a Relative Pin on the second pawn. If the pawn moved, the rook would be able to take the queen. Even if the king took back, A rook is worth 5 points and a Queen worth 9, so white would be up 4 points of material from that exchange
A rarer, although very deadly version of the pin is the crosspin. It occurs when a piece is both pinned to it's king and to a piece of a higher value. If it takes the piece pinning it to their king (If it's a legal move) then the other high value piece will be taken. 

However, Escaping a Pin is possible
Method A - Create a stronger pin on the pinning piece.

Both the pinned piece and piece it's pinned to can do this if it's avaliable. For example, if instead of a knight, white's Rook was pinned, they could move their rook up and pin the bishop to the queen.

Method B - Break the Pin by blocking it

NOTE: NEVER MAKE THE BLOCKING PIECE OF HIGHER VALUE THEN EITHER THE PINNED PIECE OR THE PIECE IT'S PINNED TO. If a knight was pinned to the queen by a rook, and you had the option of moving another queen or bishop to the same square to block the rook, then move the bishop. 

Method C - Make a forcing move, such as a check, with the pinned piece. This cannot be done if the pin is absolute
