2.45% of my blitz games end in draws.
Playing a weak, non-standard opening is surely not the only way to get interesting games, but it's reliable and easy for someone of my skill level (around 1850 on blitz.chessbase.com). It's much more reliable than playing any well-known gambit, for example.

Chess is unfortunately a game that rewards people who play to avoid losing rather than play to win.
