Other mating patterns are possible, but in general this is the mating pattern that you should try to accomplish. The diagram on the left illustrates the most typical mating pattern. It is not too difficult to force checkmate with a King and two Bishops against a lone King, but it is certainly more difficult than checkmating with a single Queen or with a single rook. In addition stalemate has to be avoided and we have to accomplish the mate within 50 moves, but after this lesson this should not be a problem. Therefor it is very important to assure that the King doesn’t capture one of the Bishops during the mating attempt. If you have further questions leave a comment.A King and Bishop alone cannot mate the lone King, but a King and two Bishops can. Hopefully this post answers your question. 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. 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.
Knight's way of moving gives him ability to "do the impossible". Again he needs 2 moves to do this and thus he fails to save the game. 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.
The following example demonstrates clearly what I mean: Remember this: Knights experience great difficulties when they need to reposition themselves between short distant squares in a short notice. In the following diagram you will see that knight needs more moves to reach the mating square, which enables the weaker side to draw: Īnd here Ne2 needs 2 moves to reach c2 and deliver checkmate. 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. Here, bishop needed 1 move to reach the mating square. Without the ability to create zugzwang you are just not able to corner the opposing king.ĭEMONSTRATING KNIGHT'S INABILITY TO POSITION ITSELF PROPERLY :Īs for the positioning problem, we shall take a look at the below diagrams: This means that he can not create zugzwang, or as you say he can not "lose tempo" to force Black king away. Why is this endgame only a draw? Because White can not move and keep control over c2 square. Now analyze this position with a knight instead of a bishop: As you say in your question, White will "lose tempo" and force Black to move his king away.
This position is won for White because he can play with bishop and retain control over c2 square ( 1.Bh7for example ), which will create zugzwang. Take the following position as an example: They can not do it because they can not move to another square while keeping the previous one in control ( like bishop and many other pieces can ) and because they need too much time to position themselves properly.ĭEMONSTRATING KNIGHT'S INABILITY TO "LOSE TEMPO" : What are the explanations, why knights cannot create an extra tempo There is a mating position with this but no extra tempo to do it in This is related to a drawback in the way knight moves. Theoretically, the checkmate is possible, but you can not do it in practice unless the weaker side allows you to. Is it really possible to checkmate with two knights and king against a
