Interference
Interference plants a piece between two enemy pieces on a line, cutting the connection: a defender loses touch with what it was guarding, or two pieces stop protecting each other. Often the interposing piece is sacrificed for the disruption.
How to spot it: find two enemy pieces linked along a rank, file, or diagonal (a rook defending a mate square, say). Ask whether you can jam a piece onto the square between them, severing the defence for one crucial move.
