Indian Defense West Indian Defense Double Check in Chess

In the Indian Defense West Indian Defense, the “Double Check” motif is a tactical sequence where one move gives check to the enemy king twice at once—typically by combining a discovered line with a second checking piece. For this opening family, it often arises from the West Indian setup (…Bb4 or …Ba5 ideas, plus central/diagonal pressure) where your pieces can coordinate to attack the king from two directions. The defining feature is that the checking move is not just a single threat: it simultaneously attacks the king with two lines (e.g., rook/bishop/queen plus a second piece).
