Pieces promote in the order of: Iron --> Copper --> Silver --> Gold --> Platinum --> Jeweled. Do you think that these problems could be solved by adding a leaper or rider? Another problem is that an iron reaching the back rank would be trapped. Currently, I solve that by saying that only the iron promotes on the back rank, and only to copper, but that seems to make the promotion optional, even though I want it to be mandatory.
