Modified Chapman:  In the Chapman System, both players on a side tee off, then they switch balls.  Player A plays Player B's  drive, and vice-versa.  Each player hits his or her second shot.  They then select the best of the second shots, and from that point until the ball is holed they play only one ball in an alternate shot format.  Switch balls after the drive, select the one best ball after the second shot, play alternate shot until the ball is holed.  The player whose second ball was not chosen gets to play the third shot.
