Indians Rule Everywhere - II

Another King's Indian Defense played by me and a rare game where black equalised in move 17 and went on to play equal position until move 32 where white did the obvious looking penultimate mistake to lose the game. Thats why I said in part - I King's Indian Defense is prone to mistakes.
