Patience in attacking
Often when an attack is being mounted there is a tendency to look for decisive moves. And for good reason, forcing moves -- checks, captures, threats of checkmate -- are often the most effective. But sometimes there is no overpowering blow and the right idea requires a little more time, or a little more subtlety.
Below is a game where after opposite side castling I sensed that I had enough attacking force headed toward the enemy king and that the defense was lacking. At one key moment the opponent's queen was defending a few key squares and I had to pause the attack and push the queen to the other side of the board before resuming a successful attack.
