I see plenty of information stating that a Knight and King vs a King is a Draw because a mating position is not possible. I also see that it IS possible, no matter how unlikely, to acquire a mating position with 2 Knights, therefore that would technically NOT be a Draw. I would "assume" a Knight vs a Knight (no pawns) is also a Draw, but I don't see that stated anywhere. Does the extra Knight on the board allow for the possibility of a mating position? For example, somehow blocking it's own King in. If so, does anyone have an example?
Yes, it is indeed possible :) I'll give you the coordinates for the pieces in a possible mating position, and you can set it up on your chessboard.
Place the White King on g6.
Place a White Knight on f7.
Place the Black King on h8.
Place a Black Knight on g8.
6nk/5N2/6K1/8/8/8/8/8 w - - 1 1
In that position, Black's King is checkmated. Although, I doubt even the biggest beginner would ever let that happen to them :) You would only be able to checkmate in that endgame if your opponent literally played the worst moves multiple times in a row.
