bishop&knight vs. lonely king The technique for mating the lonely king with bishop and knight is easy once you have the king in the corner with opposite color of the bishop. However i find it rather difficult driving the king to that corner by force from an arbitrary start position. Is there a general technique for accomplishing that ?
thanks for your help

yes Practise it.

There is some technique regarding triangle thinking...

however just imagine red squares where the other king can't go and force him to the last rank. afterthat remember that it is possible to checkmate anywhere on the last rank if the king won't move to the corner where the bishop can mate it.

No! it's possible only if he plays bad moves; you can force mate ONLY on the Bishop's color (not the opposite, John) corner.

brunetti i've seen some GM (i think, they were at least IM's-one was played in 1995, in budapest, Enders (2480-Muir (2340))games where there has been a winner. also, the knight should move little, and should be on the same colour of squares as the bishop as to attack the opposite colour.
i quote "the ending is a win but even with perfect play it can take up to 33 moves if the superior side's pieces start off badly placed...". it is very hard. i have played this ending, and drawn, on a few occasions, twice playing myself...

brunetti I think you misunderstood. I meant forcing the king to the other corner it is necessary to know that mate can arise if opponent's king do not comply.

I misunderstood. What do you understand from "remember that it is possible to checkmate anywhere on the last rank if the king won't move to the corner where the bishop can mate it"? :)

to all Absolutegenius is quoting from the book "Essential Chess Endings" by James Howell (you might have mentionded that) which presents the example that you are talking about. That was not the question. The question is " Is there a general technique for driving the king into the opposite colored corner, (or lets say to the edge of the board)". I know the mate should be in the same colored corner as the bishop. Once you have him in the other corner, you can drive him there by forced moves.

jh This was discussed quite a while back and as I said I read something about a triangle thinking technique, I think mentioned from tonlesu or calmrolfe (the two undiputed masters of chess history here).

Myself I think in redsquares (squares that opp. king cannot step on).

For a short explanation of checkmate techniques using Bishop and Knight you could try here....

Oscar I seem to remember keying in the full technique for achieving this checkmate starting right from the worst possible position, maybe round about September 2001 ? Unfortunately I didn't save it on my wordprocessor and sadly I don't have time to key it all in again. :(

Kind regards,

Cal No worries I use to practise in my head ;).

However I'm very scared by this Oscar guy because he has stolen my first name AND he seems to play english. Being very paranoid I don't like this ;).

johnholland Once you understand the technique of this basic endgame, practice it in the following way: Put the pieces in one difficult position, and practice it against a friend. In a first stage take your time. When you get more skillful, do the same but with clocks. One of my friends and rutinary adversaries in my city is FM Carlos Garméndez. He loves to set the clocks: 1 minute for him, whatever for his opponent. He always wins with ease.

Best wishes.
