The Double-Corner Trap

The two rightmost/leftmost back-rank squares are the weakest squares on the board.

Because corner squares have only one diagonal, a piece trapped there is nearly immobile and easy to win.

Force trades so your opponent's pawns pile into the double corner; then a single well-timed jump clears them.

Conversely, never let your own pawns drift into the corner unless they are about to promote.

Principle: Herd enemy pieces into the corner, then capture.

Practice this principle
