bishop and knight checkmate

does anyone know how to checkmate with knight and bishop? if you do please post and show me how with the board. thanks so much:)

You must restrict your opponent's king and direct him to the corner which your bishop can control (a1 or h8 for dark-squared bishop, a8 or h1 for light-squared one). These actions are primarily done with king and bishop

Primarily done with the bishop and knight, the king is used mainly to force the king closer to the mating square. 

bring the opponents king to a corner which has the same colour as your bishop. You get it easyly to the edge and when you have it there you have to build up a blockade with bishop and knight to prevent that the king can escape. I wont show he whole method now but just imagine a white bishop on b4 and a white knight on d4. Blacks king is on b6. This is the perfect blockade. Blacks king cant escape because of the nice piece coordination. Even when you dont know the exact method you can try to reach this blockade and win very simply.

Here's a youtube video on one technique:

Hope this helps; I learned a lot from it.

This is a fascinating mate and well worth the study, even though it very seldom comes up in practice. But watch this video of the women's World Chess Champion failing to manage it in the required 50 moves - her face (and her opponent's!) are priceless ...

There are two main methods, just enter Bishop and Knight checkmate in youtube and you'll get the material. Practise it regularly against a computer, you won't regret it should it ever come up.

I speak from experience :) I had this fantasy of playing out the mate in the final game of a Live tournament here, last game running and knowing that everyone's watching ... I actually got it a couple of weeks ago for the first time, 2nd to last game in a 10|0 tournament, I had 90 seconds left from the moment when there were only the 4 pieces left on the board, my opponent 3 minutes, and I managed it with 8 seconds left... biggest high I've ever had! Here's the game:

It is more complicate to discuss, the examples given here are not the best technique.

yuree - I edited my annotations to show the quickest mate (move 57 onwards). Sure mine wasn't the best technique, time pressure and a racing pulse are not conducive to perfect Chess! ;)

I agree. It's not just so simple as get the king in the corner. There are some very technical methods, but they are difficult to explain. Try to youtube the methods and, failing that, pay a coach 1 hr lesson to really get it down.

•  I sorry, I saw your notices and comments, I was thinking of 57.Kg3 move as being faster and your analysis holds. Had a bad connection and I was going to post analysis. 

Thanks yuree!

Thanks so much pfren, and everyone else too.

To make the procedure more simple: (Here is abroad concept to begin with.)

Overall procedure can be devided into 2 stages (each with different stratigy & handling):

1-First stage: from any given position untill the false corner (once the strong king occupied the pivotal square). despite of uncountable positional variations at start, this stage is simple & require pushing the opponent king by shouldering. any resistance of enemy king can be broken by simple zugwang with other pieces. despite wide positional variations to start with, this stage is vey simple & a beginer level.

2-Second stage: Begins when strong king at pivotal square, then knight kick from false corner, edge manouvering, till the the strong king occupy one of the two mating squares. (the finishing is simple again), this stage contains all headache, almost all mistakes occures here, but can be tought quite easily because of limited variations in positions. one thing you should keep in mind is that, this stage (the edge method) does strictly requires configuration of bishop & knight according to triangular method, although the basic idea is similar in formation of different forms of barriers. (this can eliminate confution when studying different reference materials ).

surprisingly at the first simple stage, stockfish 8 sometimes fails to calculate & find # route. (may be it is less efficient when facing longer sequence moves, despite being simple stratigy against which apparently not programmed with in this case ). but in the 2nd stage which is master challenging, it can find the # sequence at glance, because the number of moves becomes fewer.

This is a good video by agadmator:
