My friend moved his King into a position in which by my king taking his, would put my king in check.  He says this is not allowed, because my king will be in check.  I think that because when I take his king the game is over, my king would not be in check?  Please help us with this dispute.

He can't make that move. You are not allowed to move your king to a place where it may be taken, no matter what your next move would be. Tell him that the rules say that he must make a different move.
