Attacking is Not Always the Best Option

When I was younger, I only knew of one kind of style: attack! Now older and wiser, I've come to realize that attacking is not always the best solution to every position.

Here's an example of how an attack goes awry. My opponent decided to attack in the late opening, neglecting to fully develop his queenside pieces. All the while, I was quietly developing and waiting for him was the full force of my pieces.

(By the way, I've noticed that this sort of tendency- to attack regardless of the position- seems to be a problem of younger players.)
