Nimzo Indian Defense Double Check in Chess

In the Nimzo Indian Defense Double Check, a player creates a position where the opponent is checked twice at once—typically by combining a discovered/line check with a second check from another piece. In Nimzo structures, this often appears after Black’s …Bb4 pins or fixes the center, enabling tactical moves like …Nf6 and …e5 to open lines for a second checking attack. The defining feature is that the checks are coordinated so the opponent cannot simply respond to one threat.
