I agree that draws aren't a problem. They aren't that frequent at
subgrandmaster level and grandmasters can decide for themselves what suits
them best. But for the record, I would suggest the following solution to
this non-problem.
In the Yugoslav Soccer Championship, draws led to overtime and penalties,
but the penalties were shot before the overtime. Hence, the players knew
whose interest it was to attack. Following that idea, how about a blitz
with inverted colors giving half a point to the winner and a third of a
point to the loser should the real game end in a draw?
