automatic draw
King and Knight vs King

I'm in a game now where this is a possibility against a higher rated player so a draw is a gain for me. :)

A checkmate position is possible, so maybe not automatic according to the new rule. White: Kb3, Nc2; Black Ka1, Nb1.

For sure. A pawn ending where one side also has a piece is normally a routine win for the stronger side: In a King and Pawn ending it's often useful to be able to waste a move in order to make the other side move when they would rather not. Obviously, with a spare minor piece you can do this as often as you like (a spare Rook or Queen is, of course, a still greater advantage).
A point of clarification: there is no such thing as an "automatic" draw. Draws have to be claimed by a player, then verified by a tourney director. In the case of chess.com, the TD is a computer program that acts very quickly indeed.
And yes, K+N v. K+N is a draw condition.
There ARE positions that are drawn automatically. If you end up in a position where it is not possible for either player to perform a checkmate with any series of legal moves, then the game is drawn right away. This is clearly stated in the FIDE Laws of Chess.

The game is drawn when a position has arisen in which neither player can checkmate the opponent’s king with any series of legal moves. The game is said to
end in a ‘dead position’. This immediately ends the game, provided that the move producing the position was legal. (See Article 9.6)

The game is drawn when a position is reached from which a checkmate cannot occur by any possible series of legal moves. This immediately ends the game , provided that the move producing this position was legal.

I've been working on the technique to win with two knights when my opponent has a single pawn. The pawn can never be captured as that would be a drawn position. I know the method begins by blockading the pawn with one of the knights. That knight cannot move unless it's maneuvering to deliver checkmate. That usually only happens after the opposing king has been cornered by the king and the other knight.
That's my difficulty! I have trouble corralling the opposing with my king and other knight. So, here's my question: Is a king and one knight enough to force the opposing king to the edge of the board? It appears not; or, at least, I haven't figured it out.
Is this winnable or an automatic draw?
