Mating with a Knight and Bishop

[Guitarmaster7272]

damn, I love this. And btw, knowing "how" to get to this position isn't very important... I had no idea how to do the mate, but I could put the pieces into any random spot, and with enough playing around and experimentation, I could get the pieces into this position, so it's not all that hard to figure out. Also, I thought the whole idea about the barrier at 3:00 was incredible, I never saw that comin

[bpa23]

From 4:55 and 4:56 I learned the most(!!!). Never thought that wasting tempo could mean winning the game =). Thanks now I understand the W-Manouvre better.

[07joewatson]

There is no question that this video coupled with Stars Wars styled Prequel is very informative. HOWEVER, if I may add. At 2.31 in this video You say "so he plays Kc6", BUT Kb7 is so much trickier to mate him. I don't know if you still make videos but I for one would love one more addition to see this Series complete. lol, I dont half talk some pish sometimes. but what I'm telling you is true.

[harKazoid86]

absolutely brilliant!

[irshad619re]

this one helped me but if any bad player is playing like thinking that they will loss and they will not try to escape so what we will do at 2nd position if you pleas make a video which is totally forced and mate

[irshad619re]

this video helped me now i am in school team because of this video

[DanielManahan]

Get the Bishop and Knight to the middle of the board with the Bishop protecting the Knight two squares away. This will create a protected fortress for the two pieces as your king Zugzwangs the King to the edge. You won't have to move the Knight and Bishop much and will do most of the work with your King trying to stay on oppposite color as Bishop.

[america123jeff]

The title sounds a little perverted. Lol! But great video. And also to the people who say black should just forfiet. You can only have 50 moves after there are no pawns. Then its a draw

[xnoel]

i didn't knew that you can mate with a bishop , a knight and the king. good vid

[MaryJane3974]

That's a 'V', not a 'W'

[twofaces31416]

Amazing man...!!!!

[MrDudeErNeSt]

Good job!

[skerskies]

but you got king . the king helps a lot lol

[MrDudeErNeSt]

@skerskies King is just like a pawn! except it can move backwords!

[cm3007235]

at 2:30, what do you do if black plays Kb7?

[dastrn]

@cm3007235 nothing different. I cut him off from going to a6 with Bd3

[olivercarlehed]

What would you do if the bishop was on a black square instead from the beginning?

[dastrn]

@olivercarlehed Push him to H8 instead of A8.

[olivercarlehed]

@dastrn Yeah I thought so too, but I think the king will be able to escape to the left then.

[DestinyQx]

so, i have a question, if both players are really good and know a lot about chess and one player finds himself in this bad situation, wouldn't he just forfeit, knowing that his loss is inevitable? oh i see, it's more of a learning tool, to learn basic stuff about chess

[dastrn]

@DestinyQx At any level above 1800 or so, it would be assumed that both players would know how to accomplish this mate, and a resignation is likely. Below that, I'd play it out from the losing side to make the guy prove he can do it.

But yes, the exercise of learning this mate is extremely useful in understanding how minor pieces cooperate.

[crackerjack113]

anyway, it's not really that hard to get the king to the edge of the board

anyone with a basic understanding of the dark and light squares (using the knight and bishop to control opposite colors) or anyone rated around 1600 UCSF should be able to do it easily

[crackerjack113]

I LOVE THE TITLE LOL

[crackerjack113]

pretty cool but this position NEVER happens LOL

i've seen it only once my entire life

[Antharis79]

If you want to know what a REAL PAIN IN THE A** is, try to mate Fritz 11 or Rybka with knight+bishop from a position where the black king is in the midde of the board (not that starting position in this video) on highest level... ^^ :D

And then again try it within the 50-moves rule! Good luck! ^^

[dastrn]

@Antharis79 It takes me about 20 moves, give or take a few. Not too hard when you learn the key concepts.

[Antharis79]

@dastrn

Fritz 11 - 16 ply: (w)K on b2, (b)K on e5, B on c4, N on f2:

1.Kc3 Kf6 2.Kd4 Kf5 3. Nh3 Kf6 4.Ke4 Kg7 5.Ke5 Kh7 6.Nf4 kg7 7.Bb3 Kh8 8.Ba2 Kg7 9.Bd5 Kh8 10.Kf6 Kh7 11.Bc6 Kh8 12.Ng6+ Kg8 13.Bd5+ Kh7 14.Be4 Kg8 15.Ne7+ Kh8 16.Bd5 Kh7 17.Ng6 Kh6 18.Bg8 Kh5 19.Ne5 Kh4 20.Kf5 Kg3 21.Ng4 Kf3 22.Bc4 Kg3 23.Bd5 Kh3 24.Bc6 Kh4 25.Kf4 Kh5 26.Be4 Kh4 27.Bd5 Kh5 28.Bf7+ Kh4 29.Ne3 Kh3 30.Ba2 Kh4 31.Nf5+ Kh3 32.Bd5 Kh2 33. Ne3 Kg1 34.Kf3 Kh1 35.Kf2+ Kh2 36. Be6 Kh1 37. Bc8 Kh2 38.Nf1+ Kh1 39.Bb7#

[Antharis79]

@dastrn

So there are two possibilities:

-Eather you can think EVERY move far more than 16 halfmoves ahead, or

-Fritz is a complete idiot,

I think both sides are wrong. But I admit it is always possible to mate within 50 moves, but I only want to say your "20 moves give or take a few" claim is much too optimistic. There are postions it might be possible in 20 moves, but others are much more difficult, especially if the enemy king is near a corner of the wrong bishop-colour. Greetings ^^

[Antharis79]

@dastrn

And last but not least, Wikipedia:

"The bishop and knight checkmate in chess is the checkmate of a lone king which can be forced by a bishop, knight, and king. With the stronger side to move and with perfect play, checkmate can be forced in at most thirty-three moves from any starting position"

So, in most positions it takes longer than 20 moves. Ok. Enough now! Greetings.

[dannyp136]

cool

[TheEndlessNote]

thanks! thanks! and thanks!

[frozencloud17]

This is nonsense. Of course mate is coming when the king is placed against the wall. Let's see you mate the king when it is placed at the center of the board.

[daverobmessina]

thanks, you should do the two bishop one

[irascibleculprit]

wow

I really enjoyed your vid

It helped me a great deal

[M0NKEYDLUFF]

i know (king + queen) (king + rook) king + rook + rook) (king + wbishop + bbishop) now im on this one! lol =D

[ostric84]

Thanks

[jerseyknight]

This is difficult in blitz I've only worked this out 2-3 times out of maybe 10 opportunities.

[Barretron]

This video is definitely the most informative of all the BNKvK videos. Thank you!

[ecspade]

Thanks! I'm glad to be useful in whatever way I can.

[badjaeaux]

@ecspade Thank You !!! God Bless you ecspade for your Good Work +D

[BlackCatBlackful]

I am sick and tired of these crappy videos. Anybody can do this if the king is in a corner or wall, but an explanation on how to get him there would be helpful ffs...

[ecspade]

Read the comment below yours. I've already posted on how to get this position in another video. Check my channel.

I swear, people bitch more about free information than you would ever imagine is possible.

[freaky011]

@BlackCatBlackful: isn't that what the video is about?

[ckalexan]

As you say ... I enjoyed this video but its not complete.

You see its easy to mate a king when you have a position like this.

Although its completely different when you have a random one.

Ofcourse it can still be accomplished (talking to you frozencloud17) but it would take at least a 15min video for that to cover!

[ecspade]

Check my channel. I've got a second video that starts with the black king in the center of the board and my pieces in a corner, and demonstrates how to pin the black king to the wall and then get to this position.

[ckalexan]

its all good... thank you for the answer anyway!

[BlackCatBlackful]

can't find that one..

[john17972]

Mate can ALWAYS be accomplished in the KBN vs. K endgame against any opponent, IF you make the right moves. If you are playing the lone King side you should try to stay close to a corner that is the opposite color of your opponents bishop. If your opponent is weak you can get a draw with the 50 move rule.

[frozencloud17]

I would love to see you try to checkmate me with a knight and bishop. I'll give you a hundred moves and you won't be able to do it.

[dastrn]

Are you on FICS? We can set it up anytime. It will shock you how easy it will be for me.

[byakuugan86]

@frozencloud17 LOL

[frozencloud17]

Checkmate with knight and bishop can't always be accomplished. If the opponent's king is in the center of the board, it is impossible unless the opponent willingly cooperates and makes moves intentionally to be checkmated.

[dastrn]

That is completely false, frozencloud. It's a guaranteed win from any position, in far less than 50 moves.

Don't post disinformation if you don't know what you're talking about.

[MrFedel]

Any position, correct, but extremely hard unless you know the patterns and play very accurately.

[ivahoe12345]

@dastrn from the worst position it takes 35 moves to get the black king checkmate, so you cant really waste any time

[Cafebcs]

wow, the video worths more than i expected by the leng and the graphics :o

[nojameson]

Well done, this is a good demonstration of a practical method which forces mate as quickly as possible against an optimal defence! Here's another way that may be of interest:

1. Bh7 Ke8 2. Ne5 Kd8 3. Ke6 Kc7 4. Nd7 Kb7 5. Bd3 Kc6 6. Bf1 Kc7 7. Bb5 Kd8 8. Nb6 Kc7 9. Nc4 Kc8 10. Kd6 Kd8 11. Na5 Kc8 12. Bd7+ Kb8 13. Kc6 Ka7 14. Bc8 Kb8 15. Kd7 Ka7 16. Kc7 Ka8 17. Bb7+ Ka7 18. Nc6#

[Rani9000]

great video, thanks

[NorskeDivision]

I've gotten this position twice with that dumb chess computer that comes with Vista, that thing plays SOOO defensively.

[NorskeDivision]

Great video. Thanks for posting!

[taipan342]

excellent video, I learnt alot from this...thanks!

[ecspade]

thanks!

i will be putting out another bishop and knight mate video soon. that one will explain how to get set up in this sort of position from any position. I will focus on big ideas instead of specific moves.

[ihop301]

This is an excellent tutorial. I really enjoyed watching it. Well done!

[PhillipCreeper]

This is a good video and one should practice this in case he ever is in this situation. I have never had it occur in any of my games and have only seen it once and the one with the advantage couldn't win. Still it is good to study it regularly just in case. Thanks for the video once again.

[goodnameright]

honestly, great, yet most annoying video ever. Those frantic mouse moves made me want to punch someone.

[roncpas]

Nice Job! Another note is that learning how to perform this endgame helps one understand strategies to use these pieces in other scenarios.

[gifmekatn]

thats brilliant mate i'm just figuring how to get him to the edge its not a problem when he's on the edge but in the middle.. sigh

[roger11967]

thanks

[ABCDHIV]

thank you very much sir
