The King's Indian is a hugely popular opening at all levels of chess. Rather than attempting to secure early equality, Black is fighting for the initiative from the very first moves. White is allowed to build up an early central advantage but Black relies on the middlegame, hoping that the central installations that White has constructed will become unwieldy and vulnerable to a devastating counterattack. In many variations, White pursues material or strategic gains but in return Black has tactical and attacking opportunities. The King's Indian Defence appeals to players who arrive at the board prepared for a fight.
