Seems like a good opportunity for Quackle to go beyond
just making the right play and actually TEACH the user
WHY certain plays were considered or discarded. 

Let's assume that the 5 tiles left in the bag cannot be
any combination of letters that produce 64-point QI or
ZA plays, or other high-scoring prospects.  Then, the
60-point bingo would almost certainly lose the game
(still trailing by 30, no way to catch up).  An expert
player knows that cultivating the rack with an eye
toward bingo-ing OUT is the only way to win;  Quackle
should understand that, too.

It would be nice to have an option (maybe a checkbox) to
always include the highest-scoring play, even if it's not
a candidate that Generate Choices would select.  Thinking
back to Maven, there was a 'Compare Moves' feature that
offered an opinion (sometimes useful, sometimes not) on
how one move stacked up against another.  Not that Maven
was perfect;  the very first time I ever saw it, it failed
spectacularly to find a winning move at the end of a game.
More on that in a footnote.

For Quackle in the here-and-now, including the highest-
scoring play, even when it doesn't meet the criteria for
a "best" play, could be very instructive, especially when
doing post-mortem.  If the game-losing 60-point bingo is
included in the Choices list, and ends up dead last in the
Sim, with a win %-age of 0, sobeit.

When Maven failed to find a winning endgame play:  Circa
1994, a friend bought Mac-Maven and we used it to do a
post-mortem on a game we played.  We wrote down all our
racks, recorded all moves played, and set about reviewing
the game.  I was behind by about 25 points with X, blank,
and 5 vowels on my rack;  opp had just emptied the bag.
All the vowels were of the A-E-O type;  no I or U.  There
was a place to play either Xi or Xu (X on TLS) for 50, 
winning the game, which was exactly what I had done. 
Maven listed a slew of 17- and 18-point plays, all of
which were AX, EX, or OX, all keeping the blank on the 
rack.  All of those plays would have lost, because my 
opponent was going to go out on her next turn.

I still remember being shocked that an easy 50-point
play like Xi was not listed.  "Isn't there a way to tell
it to list the highest-scoring play?" I asked.  There was
not.  No way to override the program's opinion about rack
leave, etc.  That was a serious flaw, which I assume has 
been fixed in the intervening years (someone who saw Maven
play in Toronto, please fill me in).
