Checkmate with Bishop & Knight - Chess Network

[MrEmil20]

How do you examine like that? I'm very irriated because it only let me examine in atomic chess.

[america123jeff]

If black king moves to a3 at 5:32, move white knight to b5. Then king has to move to a4. Then move bishop to c2. Agian black king must go up. Then king to c4 and so on

[ghfreakwierdo123]

hey! greetings from pennsylvania!

[erwinicole]

Not possible if Black's King won't allow itself to be cornered.

[Zingerflugunn]

This mate isonly doable if the king allows himself to be cornered.

[MattSVK1]

thanks, helped a lot

[willlky85]

There is nothing preventing the black king's return to A3 from A4 at 05:34. With this black can force threefold repetition for stalemate.

[jherold68]

i learn something ever time i watch. thanks. 

[tailspike1]

isnt the black king already in stalemate?

[TheCapediamond]

TY FOR VIDEO...FROM BALTIMORE, MD.

[wdbiii]

I really wish I had watched your video because I just lost a game to a draw 5 mins ago b/c i had no idea how to checkmate with a knight and bishop!!! wow!! excellent!!

[xLucidDre4mx]

What is the software used in this video?

[AlDumbrava]

@xLucidDre4mx "I use CamStudio to record the Blitzin interface." Guess he uses Blitzin

[Calisme37]

At 6:38 you say you don't need the King on the board, but c5 is guarded by your King.

[okionada]

Hi from AR. Well done. Helpful. Especially liked the two-bishop mate. Clear as a bell. I embarrassed myself trying to explain that mate to my son in law the other night. Think I could handle the task now.

[TheXanthosis]

thank you for this video

[hackman1911]

This is a hard lesson. I've watched a couple vids on this and I still can't get checkmate with bishop and knight.

[Zingerflugunn]

@hackman1911 It all depends on if the king allows itself to be cornered.

[mikeusat]

That's an error at 6:40, right? The king is blocking C5, not the knight or bishop.

[Hopewellsmash]

at 6:48 you need the white king so blacks king cannot go to the c5 black square.

[nblfyb]

Wow. Thanks for this. Knight on dark square controls light squares. :D Good exercises. I'm gonna master them.

[michaeljimpogi23]

this is very hard!

[GenericPurpleTurtle]

at 5:32 why doesn't the black king move back to a3?

[ChessNetwork]

I should have included this particular 'what if' as it's become a popular question. What would ensue if K-a3 is the following: N-b5+ K-a4 K-c4 K-a5 K-c5 and if the black king tries to head towards the a1 square with K-a4, then B-c2+ forcing him back up. Hope this has helped.

[GenericPurpleTurtle]

It has, shame you didn't do so vocally :(

[KaTieZCrAZyCasTZ]

@ChessNetwork Hello, one question. Instead of moving your knight to d4 which was a great move, why wouldn't you move your king to that c4 square instead?

[ChessNetwork]

@KaTieZCrAZyCasTZ The king has a role to guard b2. If Kc4 then Ka3 and the black king is getting ready to run to b2 c1 etc...

[KaTieZCrAZyCasTZ]

@ChessNetwork Okay thank you.=]

[alex49carson]

at 6:40 the king is in fact important controlling c5 right?

[theaphotic]

true

[ChessNetwork]

@sxs0nar ur welcome. =)

[elsalfo]

If at 4:20 you moved your king to c2 wouldn't that be checkmate?

[Zapetroid]

@elsalfo No, it wouldn't. A checkmate can only occur if there are no legal moves left while the king is currently in check. Moving the king to c2 would deplete the opposing king's legal moves, yes, but it wouldn't put him in check. This would be a stalemate; the king is not in check but can no longer move, and the match is a draw--no one wins.

[alex49carson]

stale mate

[IHATENEDAH]

what do you do when on 5:23 the king goes to a3.. i know its pretty sure something verry ovious but still can someone help me please

[ChessNetwork]

Youtube user lucywierdo911 asked a similar question. I posted the answer as a comment. View the comments for that. =)

[MrLdh77]

@IHATENEDAH Nb5+ and you have another critical position



[JeremyNasmith]

This is NOT a mate you want to have to do when under time pressure! But having the knowhow at least makes it a possibility, because there's no way that it'd happen accidentally! The key for me was that although I knew it was possible to force mate with a bishop and a knight, I didn't know which corner it had to be in (one of the same color as the squares controlled by the bishop). Although I don't think I've ever reached this endgame, now if I do, I'll be prepared!  Thanks!

[ChessNetwork]

Yes. Keep the bishop's color in mind for this ending. =)

[fogfrogblog]

wow, if you can do this alone you'll be a master of manipulating an opponents movements and how to capitalize on the squares of the board!

[ChessNetwork]

Maybe so... =)

[alphalafa]

I see it is very frustrating to checkmate with knight and bishop, but it is do able!

Thank you master.

[ChessNetwork]

Yes, it may very well be the most difficult checkmate to force on an opponent.

Thanks for the comment. =)

[jezzzz1979]

thanks a million. you explain it in terms that are easy to understand... after watching your video I can complete this checkmate on chessmaster with 100% frequency... cheers. appreciate the instruction

[ChessNetwork]

Great! Glad to hear of it. Hopefully you can apply it to one of your own games in the future. I appreciate the compliment. =)

[DionMarinos]

I think its mate in 33 from the longest position.

[ChessNetwork]

I didn't know this. Thanks for the info. =)

[NUFC251081]

Well played!

[ChessNetwork]

Thank you. =)

[slashusaslash67]

Thanks for the video. I thought that it was impossible to checkmate with knight and bishop but this video has obviously proven me wrong.

Thanks!

[ChessNetwork]

You're welcome! Yes, it is possible. =)

[jhb1232]

I recently started to study this ending and have been trieing it for a few days. I recently played a game online and was confronted with this ending. I thought I had it down, but I was clearly mistaken. The knight to me is the hardest to figure out wher to place it but hopefully this video will clear things up. It seemed easy when you did it.

[ChessNetwork]

Great! Keep at it. Thanks for the feedback.

[mahanhen]

i will continue to watch your videos in hopes it magically makes me better. lol. nice vid

[ChessNetwork]

Thanks for the compliment. Do keep in mind that I am not a David Blaine. =)

[llEricBananamanll]

Thanks for the video.

Not sure if this is a short or long answered question, but why were you trying to get the black king into a8 or h1 rather than a1 or h8?

Is it generally better or just something in this case?

[ChessNetwork]

The corners h1 and a8 are the only squares that checkmate can be forced on the black king since the bishop travels on light squares. If there were to be a dark-squared bishop, the only corner squares that checkmate can be forced on the black king would be on squares a1 and h8. In summary, checkmate is dependent upon what color squared bishop one has.

[HappyHungYO]

This is amazing, but will take practice to memorize and execute.

[ChessNetwork]

Thanks. Yes, practice makes "almost" perfect. =)

[bobbereight]

Have you ever used this in a rated game? ( or threatened it, but your opponent resigned )

[ChessNetwork]

It's a rare ending. I have never used this or threatened to use this in a rated game.

[LonelyBoy15145]

At 5:15 couldn't the black king stay on a3?

[ChessNetwork]

I should have included this particular 'what if' as it's become a popular question. What would ensue if K-a3 is the following: N-b5+ K-a4 K-c4 K-a5 K-c5 and if the black king tries to head towards the a1 square with K-a4, then B-c2+ forcing him back up. Hope this has helped.

[amosobadja]

In this line, after ...K-a5, it's also possible for White to go straight for the quadrant trap (B in d7, N in d5) by B-f5. Then a)...K-a4 B-d7 K-a5 N-c3->d5; b)...K-b6 B-d7 returns to main line; c)...K-a6 K-c5 K-a5(...K-b7 B-d7 Ka8/b8 [...Ka6 N-c3->d5] Kb6)N-c3 K-a6 N-d5 & Bd7. This is what I like in the Quadrant Trap method: you can go for the trap whatever Black plays, and when the trap has been established, it's practically(!) impossible to blow it...except that in chess all is possible : )

[borhan21]

Great lesson but Majnu method much more easy to understand.

[ChessNetwork]

Thank you for the compliment and feedback! =)

[mercscout]

yep ^_^ and i don't mind, i'd do a lot of these mistakes if i were to make the vids so im not too critical of this stuff, since i'd mess up bad. what program is this!?!??!?!?

[ChessNetwork]

I use CamStudio to record the Blitzin interface.

[mercscout]

at 6:55 or around that, the king has c5 that he blocks ^_^

u claimed that even without the king the squares are blocked

u probably noticed but just in case :)

[ChessNetwork]

You're right! A mistake by me. :(

Another viewer pointed this out as well.

Practice makes perfect?! =)

[jujitsu100000]

oh ya.. one question.. why must the black king move from c2 to b1 (4.12 minutes) y don't it move from c2 to d2.. to get out of your wall..

[ChessNetwork]

He doesn't have to. Keep in mind that I can't cover all variations. I just tried my best to cover the meat and potatoes of this type of checkmate. Moving from c2-d2 would have put up more resistance. Good point! =)

[cilraycil]

good.thanks!

[furrer08]

Nice!

Just one thing at 6.40 you say you dont need the king on the board, but what about c5?

[ChessNetwork]

Hi and thanks. Yes, that was an error on my part. =(

Not the first to notice, but good eye nevertheless. =)

[edmalikin]

It is important to get the black king to the corner and it takes time.

[ChessNetwork]

I agree. It does take time.

[betryke2]

how come you speak so intelectually

[ChessNetwork]

Ummm. I don't know. What words did I speak which gave you that impression?

[dronai]

That was not easy !!!

[ChessNetwork]

I agree. This type of checkmate is likely one of the most, if not thee most, difficult checkmates to figure out.

[MAfr3ak]

what is the most diffucult?

[ChessNetwork]

Probably this one.

[MAfr3ak]

i agree, unless 2 knights vs king, but the other person has to have a pawn the the king blocks, which is only forced if the pawn is in a certain position

[ChessNetwork]

Very true! =)

[pte61kelly]

After 19.Nd4 the king can go back again with 19...a3!

[ChessNetwork]

I should have included this particular 'what if' as it's become a popular question. What would ensue if K-a3 is the following: N-b5+ K-a4 K-c4 K-a5 K-c5 and if the black king tries to head towards the a1 square with K-a4, then B-c2+ forcing him back up. Hope this has helped.

[SivakD]

This is one mate that I'd hate to try to force in a real match. It's neat to see how it's done, but it looks so tricky.

[ChessNetwork]

Yeah. I've never had to do it in a game either, but you just never know! =)

[SkyDimples]

dude your godly..

[ChessNetwork]

Haha. Not quite, but thanks for the compliment.=)

[sallom899]

man thats awesome to find a video like that ,ill be waiting for more ! >:)

[ChessNetwork]

Great! Glad you liked it! =)

[000warts]

You are super. Are you a chess grandmaster?

[ChessNetwork]

Just a National Master. Thanks! =)

[000warts]

Hey thx for teaching us newbies how to play chess. Any other form of checkmate videos?? You explain everything better than a book. :)

[Shmako1]

Thanks for the great video, you are helping people every where with your knowledge :)

[ChessNetwork]

It's that very notion which motivates me to continue making more videos. Thanks! =)

[fredengh]

WRONG! Look at move 19 for black. Why did the king just move down to A3. The problem with this scenario is that implies a mistake is made by black. But, I like the commentary.

[ChessNetwork]

What is wrong? I did receive a comment which I address concerning the Ka3 move. Check the list of comments to this video if you're interested in my reply. Thanks for the feedback!

[mv5207360]

Hi im very interested in chess playing, i understand it is very difficult, now i know the basic moves but do not know how to improve. what do you recomend for my improvment, how do i advance in my chess playing thanks by the way great videos keep up the good work

[ChessNetwork]

Great! My suggestion on how to improve is to play those better than yourself! =)

[gmesncomps]

one noob question

is it really possible to mate with just b/n within 50 moves if the opponent plays perfectly?

[ChessNetwork]

Yes! Checkmate can be FORCED!

[Capachm]

what is your rating?

[ChessNetwork]

Currently around 2250 USCF

[MediumKuriboh]

thanks, that was good.

[ChessNetwork]

I appreciate the feedback! =)

[ChessNetwork]

Thanks! =)

[medra1980]

(and i'm not saying you can't)

[medra1980]

Thanks anyway, i have to say i can't mate with N/B, only with B/B but you're a master so you should be able too !

[medra1980]

Yeah im not saying you suck but the educational value of this video raises questions. I mean your a national master for cryin out loud. The black king is making it pretty easy for white to mate him, f.e. what if 9. - Ke2 , 13. - Kd2, 14. - Kc1, 20. - Ka4, 21. - Ka5. If you add all the extra moves it takes to get the king where you want him too i think 50 is pretty close by if not passed.

[ChessNetwork]

Thanks! I tried to cover what I felt was most important. Youtube permits only a 10-minute video. I couldn't even cover all the possibilites in 10 hours. In other words, I had to be selective. You should post a video addendum to my video with answers to your "what if's". That would be great! I appreciate the comments!

[medra1980]

pretty good thinking but what if the black king goes back to a3 on 05:29. I find it strange that you mate him going from a black square on the board straight across to a white square.

[ChessNetwork]

Thanks. I already addressed this comment.

lucywierdo911 had asked similar 4 months back. =)

[medra1980]

ow ok then ill check it out

[medra1980]

yeah it's true but there is a faster way to mate the king. In theory it doesnt take mùore than 33 moves to mate him that is if the opponent's king is in the middle of the board and your pieces are on the side.

[ChessNetwork]

Can't argue that. I didn't consult with a computer to provide this video. I'm sure there is a faster way.

[Dracanic]

cool thank you...

[ChessNetwork]

Glad you liked and thanks!

[petisnnake]

isnt knight + bishop + kings vs king mate only possible if the lonely king makes a wrong move?

[ChessNetwork]

Hi and no. Mate is forced in K+B+N vs K, however K+N+N vs K is only possible if the lone king makes a mistake.

[ShredderLinlin]

he say wrong at 6:50, he say he dont need the king to guard the squares he have highlighted, but the king guard the c4 square

[ChessNetwork]

You're right. I was mistaken about placing a circle there. But I believe you meant to say the c5 square. Thanks for the comment!

[thewalkthrough]

My you tell me how to checkmate with a night and a king. My dad used to know how to do it. ooo, I want to know please.

[ChessNetwork]

Sorry but King and Knight vs. King is a draw. No checkmate is possible.

[jackfruit22]

I was once in a game with just knight and bishop - I knew it was a theorticall win! but couldn't mate the king! was rather embrassing..and frustrating too!- This video clears that up..Excellent! 5 stars for this one.

[ChessNetwork]

Great! Glad this video could be of assitance to you. :)

[fieryhydra]

This is really good stuff! I needed this for a long time.

[ChessNetwork]

Thank you kindly! Glad you could benefit!

[Nathan411466]

Awesome endgame analysis. Can you please do a video

on avoiding opening traps?

[ChessNetwork]

Thanks for the feedback. I'll consider doing such a video! Thanks for the suggestion!

[Ivanilos]

I thought this wasn't possible...

Thanks, nice video 5 stars

[ChessNetwork]

Thank you! It is impossible to 'force' checkmate with 2 Knights vs a Lone King...but knight/bishop vs. king is possible.

[peboguxX]

thx! That's a really tuff endgame

[ChessNetwork]

You're welcome. I hope you benefited from it!

[ChessNetwork]

I should have included this particular 'what if' as it's become a popular question. What would ensue if K-a3 is the following: N-b5+ K-a4 K-c4 K-a5 K-c5 and if the black king tries to head towards the a1 square with K-a4, then B-c2+ forcing him back up. Hope this has helped.

[lucywierdo911]

wow you've taught me much on this video. what i don't get however is why not 19. ...Ka3 ? he wasn't forced up on move 19 and if the knight was going to check the king with 20 Nc2, wouldn't that be a draw eventually because of the 50 move rule?

[Afaceinthematrix]

Wow! Thanks, this helped me out... this rarely comes up but it makes a big difference when this type of endgame does come up.

[ChessNetwork]

Glad to know I've helped ~!

[JajaJibbidyJa]

thank you for posting this man

[ChessNetwork]

You're welcome!
