Can the elephant at C2 capture E4 while a black soldier occupies the eye at D3?
These are local movement diagrams. A real move must also keep your own general safe.
Show answer and explanation
Answer: No, either colour blocks the eye. No. The occupied D3 eye blocks the capture regardless of colour. Removing the blocker restores only the movement condition.

A clear eye does not allow crossing the river
The river restriction is separate from the blocked-eye rule. Red elephants must remain on the red half of the board; Black elephants stay on theirs.
How elephants defend the general
Elephants and advisors protect the general. Before moving, check the eye, river boundary, destination and your general’s safety.
