Indian Defense West Indian Defense Interference in Chess
In the Indian Defense West Indian Defense Interference motif, one side uses a move to block or “get in the way” of a key line—often a diagonal, file, or the path of a major piece—so the opponent’s attacker can’t deliver its threat. In the West Indian structure, this commonly appears when pieces aim at the kingside or central dark squares and a tactical interruption changes what is possible next.
To spot it, look for moments when your opponent’s active piece (typically a bishop or queen) is lined up on a crucial square, but that line can be cut by a forcing move—often with tempo. To use it, choose an interference square that both blocks the line and creates an immediate follow-up (like winning a piece, stopping a mate threat, or allowing your own piece to take over the now-vulnerable target).
