Question: It’s my move, and I don’t have any possible Jumps. While Cantering one of my Knights, I’ve reached a square where it’s possible to Jump an enemy piece. Must I do so?

Answer: Yes. The Canter of your Knight has now become a Knight’s Charge, so you must make a capturing move, either immediately, or later in this move.

This is from the WCF rules. The implication seems clear, but I wonder if it could have been better explained. I am not quite clear on just why a charge suddenly becomes a mandatory move.

Camelot (Pioneer54 vs. skinny18)

This game is ongoing, but well beyond the position linked here. I tried to move 9.Ni7-i9, but the system would not allow me to stop and submit the move from that point. Why? I had no jump, so any piece could have been moved, and cantering is supposedly optional.

Is this a site bug, rule ambiguity, or something else I missed?
