Checkmate with two knight against king+pawn!

As an average chess player i always understand some basics endgame knowledge such as king vs king, king+bishop vs king, king+knight vs king, king+two knight vs king and etc.etc are draw because of insufficient material to checkmate but recently I’ve read one article in chesscafe and i was shock to know that King +two knight vs king+ 1 pawns can offer winning chance for the side with the knights! (maybe many of you already know but this is new knowledge for me!)

Below is the most interesting example especially when you noticed that the defending player Grand Master Anatoly Karpov-former World Champion and endgame maestro lost this fascinating endgame to future World Champion-Veselin Topalov!

After looking of this game, i search for information about this type of endgame and i found that there is a theory for it. The Russian theoretician Troitsky discovered the following rule:


The Troitsky Line

"if the pawn is securely blockaded by a knight no further then the line, then the side with pawn loses, no matter where the kings are"

Ooh...i gave up already with all this kind of theory ...but for you guys, especially who are planning to be National Master, Fide Master, International Master, Grandmaster whatsoever- you better know this!
