French Defense Winawer Variation Skewer in Chess

In the French Defense Winawer Variation, a “skewer” is a tactical motif where one piece attacks a second piece, forcing it to move because the attacked piece is behind it on the same line. In many Winawer positions, the defining setup comes from the queenside structure and piece placement after moves like ...Bb4 and the typical pressure on the c- and b-files. The skewer often targets a valuable piece (commonly the king or queen) by first pinning or forcing a less valuable piece to shift.
