Rook cross attack

A rook cross attack is a square from which a rook attacks enemy pieces on both a rank and a file at the same time. The king and queen always count. A knight, pawn, bishop, or rook counts only when it is undefended. The square can be empty.

Why you should notice it

Two pieces that are not on the same line can still be forked by a rook standing on the corner between them. If you only look for pieces already lined up, you miss that square.

When to check it

During threat assessment, can *their* rook attack one of your pieces along a rank and another along a file? While finding a move, can *yours*? Pieces on only one line are a rook attack, not this pattern.

Why players miss it during games

The usual rook fork is two pieces on one rank or file. The corner, with one target sideways and one target straight ahead, is easy to skip when the square is empty.

How WayChess trains it

You draw an arrow from the square to each target. A defended minor piece is not a target, and a piece of the target's color on the ray blocks what stands behind it.
