think you are in the situation below . what will be your moves ? can you mate or no ? or is checkmate possible or no . thanks

w: Kc7

B: Ka8

W:Nb6 #

IS IT FINE?

after Nb6+ the next move is Ka7 . OK ? and the game has not finished .

Checkmating with a king and 2 knights is impossible if the other player makes the optimal move every turn

mate with 2 night and 1 pown belong to other side is possible  the pown in h7

and with just two night impossible

You can only mate if your opponent lets you. Most people just agree to a draw because they don't feel like sitting there for 50 moves watching this simple draw played out on the board...
