How Can You Checkmate With Two Knights VS King and Pawn?

One of the most difficult endgames is the two knights vs king and pawn. How do you do it? Is there a general way to win?

Yes. Every endgame manual explains it.  

The drills here offer you the chance to practice it. https://www.chess.com/drills/practice/two-knights-vs-pawn

I know about this drill, but I want a more detailed explanation about how to do it.

Force the king into the corner, while blockading the pawn

I'm sure there are resources out there with a general plan, but that endgame has to be one of the least common ones out there and one small error and it will become a draw. It's 38 moves to a win from that position, with only 3 options with mate under 50 moves.

I commend your effort and desire to want to master this ending; however, I really think you would be better served to focus on other areas for the reasons already alluded to above. Good luck, either way.

Thanks m_connors.

By the way, what do you think is the hardest endgame?

I don't know, but I'd have to say that one is in the top 3 . . .
