73. ... Ne8+ was required. But also 77. ... Ne8+ would have saved it (it's mate in 25 after that and therefore with perfect defence the game will be drawn by the 50 move rule).

when you are rated 2000 endgames like that dont really matter you are playing the best move possible.

Originally posted by XanthosNZI saw a study on the net about this ending recently (sorry, i've long forgotten where...). The IM who did it was investigating whether it is theoretically drawn. Most end game books seem to advise the defending side, as a general plan, to keep the King centralised and use the knight as a shield. He discovered that this in fact is incorrect, as there is an algorythm (which is F***ING complicated!!!) which allows the attacker to win. He in fact discovered that a counter intuitive approach is required were you keep the knight one move away from the King (always in range to jump back into defense but not physically joined). I wish i had a link, it was a great lecture, i'll see if i can find it. 🙂
