Nope..  16.13 hit 3249 or whatever. the 'bug' is _very_ difficult to produce,
it requires a lot of pieces on the board, including a queen, and it requires
one king to reach the other side's first rank, and be on the side of the board
with no pawns of any kind.  I don't think there are _any_ programs running
today that have _no_ errors/bugs of any kind.  when you have 50,000 lines of
C, the probability that one line has a bug is almost 1.0....
