Please Help with DH Rule

[bob jenkins]

You are correct in both situations.

I find it helpful to use phrases like "role of the DH" and "the player", as you seem to do. Or you could try having them read the case plays (3.1.4C is about the same as your first scenario).

SOmetimes though, you just need to remember that you can lead a horse to water, but you can't teach an old dog to make a silk purse out of a pig-in-a-poke.
