blue group · The short answer
CHESS VERBS
Each puzzle word passes the same exact test. The four mappings show how the answer works.
To CAPTURE is to remove an opposing piece through a legal move that takes it.
To CASTLE is to perform the special move that repositions the king and one rook together.
To CHECK the king is to make a move that places it under immediate attack.
To MATE the opponent is to place the king in check with no legal escape available.
Why this group was difficult
- The noun readings are highly visible
CASTLE suggests a fortified building, CHECK suggests an inspection, and MATE commonly means a friend or partner. - Chess uses the four verbs differently
CAPTURE and CASTLE describe moves, CHECK describes a threat to the king, and MATE describes the decisive position.
How to spot this pattern next time
After noticing a game theme, place each candidate into a natural sentence such as 'to castle' or 'to check the king' to verify its grammatical role.
Do not stop at words associated with chess; confirm that every entry functions specifically as a verb in standard descriptions of play.
