Right from when we first start to play chess, we are taught quick knock-out ways of checkmating our opponent's king. We quickly learn Scholar's mate and other speedy methods of scoring an easy win. At that point, the more difficult and sophisticated job of trying to break down a castled king is only a vague outline in our mind. Eventually we develop various slapdash methods of attacking the king that has fled to safety. However, it seems to me that the topic of attacking the castled king is poorly represented in chess literature, and as a consequence, very few of us are true masters of this tricky subject.
