Vigorito: The King's Indian Vol.1'The King\''s Indian remains a hugely popular opening at all levels of chess unsurprising given the attacking opportunities it offers. In many of the ultra sharp main lines, both sides can fight for the initiative. White frequently wins the queenside battle but this often turns out to be a Pyrrhic victory as Black wins the war by checkmating on the kingside! Black is hunting the enemy king and this gives him a psychological edge in practical play.
