French Defense Kings Indian Attack Double Check in Chess

In the French Defense Kings Indian Attack, the “double check” motif happens when one move gives check while simultaneously opening a second line for another piece to check the king. A defining feature is often a tactical setup around the kingside, where your pieces coordinate to attack the enemy king along two different rays (for example, a discovered rook/queen line plus a direct check). The result is a forcing sequence that can win the king’s defenders or even end the game quickly.
