Real life example
Usually a two knights ending is a draw. But in some circumstances, when the defending band have an extra pawn, this pawn will be a dead sentence.
This kind of ending has been documented in many endings books, but I've never seen a real game example.
The game included here come without comments.
Althought there are many tactical shots in the game, if you are only interested only in the ending, I suggest you to jump to move 40 an so ....
PD:.(Sorry for my poor english)
