The last part brings up an interesting point. By pushing a draw, you set up the possibility of winning the pot yourself by your aggressiveness later on even if you miss. This is an easy heads up strategy. With many opponents you build up your equity in the pot. At some point your in between the two extremes (or maybe they overlap -- hope this is clear). That is, on the flop maybe you bet hoping for callers, but don't get as many as you hope, so you switch horses midstream, so to speak, and try to steal the hand by your agressiveness if you don't make your hand, even though that wasn't your original intention.
