With just N+N v K, mate can't be forced, but if your opponent willingly goes into the corner you can win. With best play from both sides all you can get is a stalemate. If the opponent has a pawn on the board you actually can mate because the pawn's move prevents stalemate and mate can be achieved
Is it possible to force checkmate, with two knighto and a king, vs a king. If so, can someone say what the strategy is.
