Sorry I can't help here, but I run unix machines _only_ and don't have a way
to run and test the shredder interface, even if I had a copy of it.  But if it
does send a "new" before each move, then yes, I would call that badly broken
and would disregard _any_ games played under that circumstance.

All crafty needs is a "new" command to start a new game.  Otherwise it only
needs "moves" sent to it.  Doing more interferes with the way the engine
saves things in the hash, killer and history tables...
