Fifty turns is not always enough. I have played matches where one player clearly would have won after turn 50, but instead the game was declared a draw.
In tournaments, a draw is treated as a non-event. If nothing else, they should be half a win and half a loss. Something, anything, to indicate a match was played and drawn.
Ties are in general distasteful. Maybe I only think that because I am American. Nearly any way of resolving ties would be nice.
