When a king is in check, you must fix it right away by moving the king, capturing the checker, or blocking the line if that works.
Follow the lesson one board at a time. The teacher answer key includes the move list.
Solve each position on paper first. Answers live only in the separate teacher/parent key.
White to move. Find checkmate in one.
Only one rescue works here. Move the king so the check disappears.
Capture the checking rook with your bishop.
The rook's line can be blocked. Slide your bishop in the way.
White starts in check. Try legal replies only, and notice that any move which does not fix the check is rejected.
Teacher/parent key for Worksheet: Getting Out of Check and Checkmate.
Prompt: List the three main ways to get out of check.
You can move the king, capture the checking piece, or block the line when the attacker is a rook, bishop, or queen.
Prompt: How is check different from checkmate?
Check means the king is attacked but has a legal rescue. Checkmate means the king is attacked and there is no legal rescue at all.
Prompt: Look at the practice positions and name which rescue idea was used in each one.
Practice 1 uses a king move. Practice 2 captures the checking piece. Practice 3 blocks the line. The shared mate-in-one puzzle shows the checkmate idea.
White to move. Find checkmate in one.
Solution: Qa8#
The white king on g6 already covers g7 and h7, so those squares are off-limits for Black's king. Qa8 checks along the 8th rank, and with g7/h7 covered and g8 controlled by the queen's rank, the king is trapped.
Only one rescue works here. Move the king so the check disappears.
Solution: Kd1
Moving the king is one way out of check. Here, every other reply still leaves the king under attack.
Capture the checking rook with your bishop.
Solution: Bxe2
If you can safely take the checking piece, the check is gone right away.
The rook's line can be blocked. Slide your bishop in the way.
Solution: Be2
Against a rook, bishop, or queen line, sometimes you can place a piece between the king and the attacker.
