I am trying to define a capture-only move. I am writing:
(define capture-move ($1 (verify empty?) add) )
When I run it I received the error:
Missing "(" at capture-move
What I am doing wrong? |

If you are using the default chess.zrf file, "capture-move" is already defined as a move type and you will get that error message. Rename your move (or that move type) and you should have no issue. |

Missing parentheses can be one of the more annoying errors to fix. You seem to have the right number of parentheses in the line you wrote, but there may be other missing parentheses in the lines above or below which are generating this message.
Incidentally if you want a capture-only move it should be (verify enemy?), not (verify empty?). |
