Old Indian Defense Skewer in Chess

In the Old Indian Defense, an “old indian defense skewer” is a tactical motif where one piece is forced to move because it lies on the same line as a more valuable target behind it. A defining feature is the pressure along a diagonal or file created by the Old Indian setup, often involving the dark-squared bishop and a long-range piece that can line up with the king or queen. The skewer differs from a pin because the front piece is attacked and the back piece is the real prize.
