As you say in your question, White will "lose tempo" and force Black to move his king away. Why is this endgame only a draw? Because White can not move and keep control over c2 square. This means that he can not create zugzwang , or as you say he can not "lose tempo" to force Black king away. Without the ability to create zugzwang you are just not able to corner the opposing king. Here, bishop needed 1 move to reach the mating square. Notice that the endgame would be drawn , just as the one with two knights, if bishop was not able to reach c3 in one move.
In the following diagram you will see that knight needs more moves to reach the mating square , which enables the weaker side to draw:. Remember this: Knights experience great difficulties when they need to reposition themselves between short distant squares in a short notice. This is often impossible task for them. The following example demonstrates clearly what I mean:. In this position we can see how hard it is for the knight to position himself fast to a square nearby like f3 or g4.
Again he needs 2 moves to do this and thus he fails to save the game. Knight's way of moving gives him ability to "do the impossible". He can "jump over" obstacles, his attacks can not be stopped, his line of fire can not be covered or intercepted, but all these beautiful features come with a price.
He is slow and clumsy when he needs to reposition himself to a square in its proximity, and if player can not "buy" him enough time to do that then knight fails to accomplish this task.
It is possible, but it is not forced unless the position or a mistake from the opponent allows it. There is a mating position with this but no extra tempo to do it in real game. A knight always moves to a square of the opposite color. If the knight is on a white square it moves to a black square and if it is on a black square it moves to a white square. In order to create an extra tempo, you would need the capability for a knight to move to a square of the same color twice in a row, but that is not possible.
Thus, you cannot create an extra tempo with a knight. Wikipedia has a long article on this topic. Unlike some other theoretically drawn endgames, such as a rook and bishop versus rook, the defender has an easy task in all endings with two knights versus a lone king. The player simply has to avoid moving into a position in which he or she can be checkmated on the next move, and always has another move available in such situations.
Not only it is showing a lot of explanatory examples, but also speaks about really strange paradox Troitzky line which explains how the material advantage for the weaker size can cost him a game. Having one pawn against 2 knights can give white a chance to win. Also you can read another helpful resource here. Sign up to join this community. Although there are checkmate positions with two knights against a king, they cannot be forced.
It is not possible. Checkmate can only be forced with the minimum of a King and Rook, a King and two Bishops, or a King, knight and Bishop, though that last one requires considerable skill. Checkmate could theoretically happen, but the defending player would have to make a mistake and actually step into it.
Two knights endgame. The two knights endgame is a chess endgame with a king and two knights versus a king. In contrast to a king plus two bishops on opposite-colored squares , or a bishop and a knight, a king and two knights cannot force checkmate against a lone king.
However, the superior side can force stalemate…. I've given much in my life away and you know what I learned? Someone has to work hard for what you gave away. So if someone gave something to you then appreciate what you have. I don't blame you for keeping what you have to yourself.
The diagram is illegal. White's last move was Nf7 checkmate. But before that, black's King must have moved to h8 from h7, illegal or from g7, illegal or from g8 illegal. Therefore the diagram is not valid. Of course, it qualifies as a helpmate. Where are those dancing pony animated gif thingys when you need them? Forums General Chess Discussion. May 27, 1.
