Can the King Capture the Piece Checking It?

Yes, the king may capture the checking piece if it can reach that square, the capture removes every check, and the destination is not attacked by any enemy piece. Play Kxe5 in the Undefended Rook card.

The checker must be on a square the king can capture, and the resulting king square must be safe from every enemy attack. The move must also resolve the current check completely. Use the Three-Part Safety Test before answering each card.

Yes, if the queen is adjacent, undefended, and no other attack covers its square. A protected checking queen cannot be taken by the king. Compare the Undefended Rook pattern with the Bishop-Protected Queen card.

Yes, an adjacent checking rook may be captured when its square is safe. If the rook is protected by another piece or king, KxR is illegal. Compare the Undefended Rook and King-Protected Rook cards.

Yes, if the bishop is within one king move and its square is not attacked. The king must remain safe after the bishop is removed. Play Kxd5 in the Undefended Bishop card.

Only if the knight is on an adjacent square the king can reach and that destination is safe. Many knight checks come from two squares away and therefore cannot be answered by a king capture. Apply the reachability step in the Three-Part Safety Test.

No, the enemy king attacks every adjacent square, so the capture would move the king into check. Reject Kxe5 in the King-Protected Rook card.

No, if the bishop attacks the destination square after the capture, the king would still be in check. Reject Kxe5 in the Bishop-Protected Queen card.

No, a knight's attack on the destination makes the king capture illegal even though the knight is not on a straight line. Reject Kxe5 in the Knight-Protected Rook card.

No, a pawn attack on the destination square prevents the king from moving there. Remember that pawn attack direction differs for White and Black. Use the destination-square scan in the Three-Part Safety Test.

Yes, removing the checking piece may open a line from a rook or queen behind it. The king would land in the newly revealed attack. Reject Kxe5 in the X-Ray Queen card.

It is a sliding piece whose attack is initially blocked by the checker but opens when the king captures that checker. The resulting line makes the capture illegal. Trace e8-e5 in the X-Ray Queen card.

No, a king moves only one square at a time. A distant rook, bishop, or queen check must be answered by moving, blocking, or using another legal capture. Reject Kxe8 in the Distant Rook card.

The king answers check by moving to a safe square rather than by blocking with itself on an attacked line. Another piece may sometimes block a sliding check. Use Kd3 in the Distant Rook card as the safe king-move response.

Yes, moving to any legal unattacked square that removes the check is a valid response. The king does not have to capture the checker. Use the Kd3 alternatives across the protected-checker cards.

Yes, another piece may capture the checking piece if that move removes the check and leaves the king safe. The exact options depend on the position. Use the Check Response Choices section to compare capture, move, and block.

Yes, a rook, bishop, or queen line check may sometimes be blocked on a square between the checker and king. Knight, pawn, and adjacent attacks cannot be blocked in the same way. Review the Check Response Choices section.

Only if the king move captures a checker and lands on a square safe from every remaining attack. Capturing one piece is not enough if another checker still attacks the destination. Use the every-attack requirement in the Three-Part Safety Test.

Yes, a legal king capture may also create a discovered or king-supported check in the resulting position, but the capturing king's safety is tested first. Use the Direct King Check route for check-source examples.

Yes, Black may capture an undefended checking piece when the destination is safe. Colour does not change the three-part test. Play Kxe4 in the Black Captures Queen card.

A standard chess interface should reject the king capture if the destination remains attacked. It should allow the move when the checker is safely capturable. Compare the legal and protected-rook cards before relying on interface feedback.

Use normal king-capture notation, such as Kxe5 or Kxd5, with check or mate suffixes only when the resulting position requires them. The notation does not override king safety. Compare the two legal capture buttons in the trainer.

The move is illegal because the king remains in check on the destination square. In formal play, use the applicable illegal-move procedure and summon the arbiter. Replay the King-Protected Rook card to identify the attacked square.

In touch-move play, touching pieces can have consequences, so calculate the destination attacks before acting. Confirm king, pawn, knight, and sliding-piece protection first. Use the Scan Every Defender checklist.

A king protects only its adjacent squares. If one whole square separates the enemy king from the checker, it does not protect that checker by king movement alone. Use the King-Protected Rook card to see true one-square protection.

No, the capture may reveal an x-ray attack or fail to remove another simultaneous check. Evaluate the complete resulting position rather than only removing the visible checker. Use the X-Ray Queen card.

Scan the destination for long-range bishops, rooks, and queens as well as pawns, knights, and the enemy king. A hidden defender can make the capture illegal. Work through the Bishop, Knight, and X-Ray protection cards.

Pinned-piece attacks require careful treatment under the formal attacked-square definition, so do not assume a visible pin automatically makes the king capture safe. Use the dedicated King Captures a Pinned Piece route for that separate rule.

Ask three questions: can the king reach it, is the destination attacked, and does the capture remove every check? If any answer fails, Kxchecker is illegal. Replay cards one, two, and five as the core sequence.

Next study moving into check, pinned-piece captures, adjacent kings, and direct king checks. Those pages extend the same destination-safety test into related king decisions. Follow the Continue the King Route cards after completing the trainer.
