help play3 (continued from `help play2')

On a typical turn, you will 'place' a word on the board.  You can `undo'
this action until you `commit' to the turn.  Committing also draws new
tiles for you and starts your opponent's clock.  If you want to challenge
the move that was just made, 'pause' the clock and 'ospd word1 word2...'.
If your challenge succeeds, your opponent must 'withdraw'; if it fails, you
must 'pass'.  Instead of placing a word, you can also `exchange' tiles, or
`pass'.  The clock can be `pause'd and `resume'd at any time by either player.

When one player plays out and commits, or when six successive scoreless plays
have been made, the clock is paused.  At this point, the last player to play
can optionally `extend' the game if players want to continue play, or the
next player can either accept the final play with `end' or challenge the play
and request a `withdraw'.
