I don't like back to front.  It requires that stuff from the end of the
game be back-filled through the hash table.  Here are the two arguments:

1.  back to front is better... because you can use stuff happening at the end
of the game to influence scores and moves earlier in the game.

2.  front to back is better because it gives a true reflection of what the
computer would have seen had _it_ been playing that game directly.

I go along with 2.  1 means you see some bad things quicker than if you use
2.  But it also means that when the critical hash entries get overwritten,
the scores jump up significantly, which is also misleading.
