Forks (double attacks):
A single piece attacks two pieces simultaneously, forcing the opponent to make a difficult choice, often resulting in material loss.
Pins:
Attacking a piece that is defending another piece (like a king or a more valuable piece) and forcing it to move to defend the pinned piece.
Skewers:
Exploiting a line of pieces to attack a more valuable piece behind a less valuable piece, forcing the opponent to choose which piece to save.
Discovered attacks:
Moving a piece to reveal an attack by another piece, often resulting in a check or a double attack.
