[D&D 3.5] Overrunning as part of a charge?

Can my trusty little dwarf do it? He has improved overrun. If he succeeds against the guy in his way, can he continue forward and get an attack at charging bonuses/penalties against the guy in the back?

Is overrun a standard action or a move action (I'm confused by the "standard action as a move action" line) i.e. can you attack or cast a standard action spell in a turn you overrun?

My friends are pretty ironclad rules lawyers that have never played overrun, so I'm sure they will be skeptical if this does work, so as complete explanations as possible would be greatly appreciated.

Thanks again!

It won't work.

First, charge is a full-round action, so you can't combine move or standard actions with it.

Second, in order to charge the second target, you have to have a clear line of movement to that target.
[...]Second, if any line from your starting space to the ending space passes through a square that blocks movement, slows movement, or contains a creature (even an ally), you can’t charge.

Regarding overrun, it's a standard action, but you use it during movement. When you're moving, you can use a standard action to initiate the overrun attempt. The overrun interrupts your movement, which continues after the overrrun is resolved. As noted above, you can't combine it with a charge though, since a charge is a full-round action that leaves you with no standard action to overrun with.

This is all correct. It would be really cool, though. If I was DMing, I'd let the player do it once, but only once.

This makes Overrun a relevant option, so I would probably homebrew this to work. It does not by RAW.
