Who cares how to play 51 here? Right? He needs 33 crossovers to bear off all his checkers. If I play 3/0ff 3/2, I am left with 21 pips, that's at most 7 rolls. Assuming he rolls nothing but 66 from now on and I roll nothing but 21 from now on he will still lose. So why is XG shows my play to be an error?
