Over the nose or under the chin would be harsher due to the leverage being used.

When leading, a good bump is all that would be needed. But you don't lunge a horse with a chain on/under its nose or in it's mouth.
And I don't find anything with chain links to be "kind" and can only imagine the amount of pinching it would present. I'd be livid if I had a horse on training board and found out some girl lunged my horse with a chain (I'm jumping to conclusions and saying the chain from the leadrope) in its mouth.

Success is not final, failure is not fatal: it is the courage to continue that counts.
