Rook attack
The rook-attack habit (rook fork) is two opponent pieces on the same rank or file such that a rook could attack both from a square on that line. Kings and queens always count; knights, bishops, rooks and pawns only if they are undefended.
Why you should notice it
Ranks and files open when pieces slide or pawns trade. Two pieces that were not “on a rook” last move suddenly are. If you only look at knights or flashy bishop mates, you miss the quiet recapture that creates the fork.
When to check it
During threat assessment, can *their* rook fork two of yours? While finding a move, can *yours*? The blunder-check version is walking into a rook attack.
Why players miss it during games
You look at knights because knight forks are famous, or at diagonals because they look flashy. A recapture on a file can create the alignment you will only see after the rook lands.
How WayChess trains it
You identify valid rook-fork pairs and the fork square, with feedback when the line is blocked or the square is unsafe when it needs to be.

Bishop diagonal and knight fork are the same idea on other geometries. Vertical fork focuses on files. Walking into a rook attack trains the candidate that creates the pair.
