Polish Opening Other Variations Skewer in Chess

In the Polish Opening “other variations,” the key idea behind a skewer is that White can line up a piece so the opponent’s more valuable piece is forced to move, revealing an attack on something behind it. A typical defining feature is a tactical alignment after early development—often involving pressure along a diagonal or file—so one target is “pushed” out of the way while the second is hit. The result is a skewer motif: the front piece moves (or is compelled to), and the back piece takes the brunt of the attack.
