Anderssen's Opening Discovered Check in Chess
Anderssen's Opening Discovered Check is a tactical motif where, after a key move in an Anderssen-style attack, one piece’s movement “uncovers” a line so another piece gives check. The defining feature is a discovered attack on the enemy king: the checking piece was blocked until the move that creates the discovery. In many Anderssen’s Opening positions, this happens when a defender’s piece or your own blocker shifts, suddenly turning a threat into a direct check.
To spot it, look for moments when a move changes the status of a line to the king—especially when a bishop/rook/queen line becomes open because a piece steps away or is forced to move. In Anderssen’s Opening, watch for tactical sequences where your attacking piece can move with tempo, and the “real” check comes from the newly opened diagonal or file rather than from the moved piece itself. To use it, calculate one move deeper: confirm that the discovered line is not blocked again and that the opponent cannot capture the uncovering piece or interpose immediately.
Frequently Asked Questions: Anderssen's Opening Discovered Check
- What exactly makes it an “Anderssen’s Opening Discovered Check” and not just any discovered check?
- It’s the same discovered-check mechanism, but it arises in the tactical spirit and typical structures of Anderssen’s Opening—where aggressive piece activity and forced lines often create the moment a blocker shifts and reveals check.
- Which pieces usually deliver the discovered check in this motif?
- Most often a bishop, rook, or queen delivers the check once a line is opened. The key is that the checking piece was previously blocked, and the Anderssen-style move uncovers it.
- How can I recognize the setup during calculation?
- Before committing, identify the king’s lines (diagonals/files/ranks) and ask: “What piece is currently blocking a direct line to the king, and can I move or force it to move?” If one candidate move opens that line and gives check next, you’ve likely found the motif.
- What’s the most common mistake when playing for this discovered check?
- Assuming the line stays open: opponents often can capture the uncovering piece, block the line immediately, or gain tempo by attacking your checking piece. Always verify the discovered check is legal and decisive after the opponent’s best defense.
