I can't see that Kasparov would offer "Drawer" a draw for every game.  Wouldn't
he beat it?

The likelyhood of this situation is remote.  The draw offering is hypothetical,
and the draw accepting is a bug that will serve to reduce "Drawer's" rating.
Drawers programmer needs to remove this bug before all the other programmers
catch on & instruct there programmes to offer draws in losing positions in comp
v comp games.

As in life the RUDE programme does better because of it's rudeness (offering
draw from losing position).  Being polite and standing back won't get you very
far.  Just ask the "pirates", they know who's got the most.
