A contradictory view on heads up strategy

[J_V]

Everytime you ask for general advice about heads up play, someone comes running in suggesting the aggressive/maniacal play is the way to go.

They suggest that most of their profit comes from them running over other players, or profiting because their opponents fold to much.

However, I have played all levels of competition (exclusively online) from world class players to total fish and I find that my profit does not come from this area.
In fact, I feel that when I win (which I don't always do) its because my opponents pays off too many hands too hard. Essentially, I could talk out a strategy very quickly in words as to how to beat a player. If I can't talk out a winning strategy verbally to myself, I usually stop playing.

In general though, I have never met a player that played me head up that plays so weak tight that he folded the flop everytime without a pair or draw. And, if they start off this way they are not dumb enough to not realize they are being robbed blind.

So, I would like those of you that play heads up online (5-10 and up) to comment on this.

Thank you.
