Chess Endgame: Queen vs. Knight

[mokubunshinnojutsu]

i find it very easy to understand, thank you sir

[fiddlercrab3]

5:43 "He has two knight checks, but they're both covered by my queen." I assume, of course, you mean because the knight is *pinned* by the queen, right? :-P

[christinelindauer]

Thanks for the video, I found your approach of focusing on the geometry of the knight to be very useful. As a minor point, I believe the pronunciation is or-THAW-guh-nuhl, with the emphasis on the 2nd syllable just as in di-AH-guh-nuhl. Separately, I don't think it means what you think it means, but your message comes across anyways, and what are words for after all?

Thanks.

[bEEny44]

thank you very much

Orthodontics is about repairing teeth. The closest word I know to what you are saying in the video is "orthogonally" which is a mathematical term with a meaning related to axes at right angles. Also, you often refer to pieces being 2 squares apart when the distance from one square to another is actually three and there are two empty squares between the pieces. Sorry if I am sounding pedantic and unappreciative. I have enjoyed your videos and they are far better than I could do.

@protheric I guess the phrase is "orthogonally adjacent" but gets abbreviated "orthogonally" sometimes, so I never learned the correct phrase. boardgamegeek (dot) com (slash) thread (slash) 401731 (slash) ok-ill-ask-orthogonally-adjace­nt

[aeiou99999]

Thanks. I think you may not be giving black his very best defense, but I nonetheless got something valuable out of this and appreciate your effort.

[GreenCastleBlock]

@aeiou99999 Blame the computer I was playing :p

[GusCollias]

I. Q forks n and k...II.  Qd7, defended by k mates.....but liked vid.

[leoholsbach]

GreenCastle is pretty cool guy, he ain't afraid of checks nor anything.

[sycilmathai]

thanks for posting

[ourtortsystem]

at 3:45 the best way it to play queen e5+ - wins the knight right off

=)

[KeepitRealisrael]

Great vid... I was stuck with this for 2days... but as soon as I watched this video I am not able to tackle this issue... Thanx

[bernthalcraig]

Thanks Matt. I just lost this endgame to WIMP B. Will try to remember the geometry next time.!

[aquarian817]

i was wondering what will happen in case of rook vs the night.

[fredb1978]

The queen could have also forked the king and knight (which is a check move) and the queen will win the knight that way also. I am referring to the example in this video when the king is not close to the knight so he is not protecting it.

[GreenCastleBlock]

@fredb1978 That is supposed to be an abstract example. Ignore the kings.

[benbisley]

Thank you. Good teaching.

[nomindchess]

great job. very helpful especially how you showed it in the beginning. silmans book doesnt talk about this but just says watch out for forks, take it slow, etc. thanks matt

[pikuelo]

thanks, mate

[geekorthodox9]

If I might ask a question, what software are you running to pull up these endgame puzzles?

[rocco133]

thx greencastleblock ^^

[xxxxDre4mxxxx]

didnt really explain the proccess at all . . . thus not really learnt anything.

[GreenCastleBlock]

different people learn differently I guess, sorry you didn't learn anything

[fezzjr]

umm you play it like a k queen vs k but you watch for knight forks and slowly back him down as shown above... the knight stuff at the beginning BTW has helped me more than the main topic tho lol

[xxxxDre4mxxxx]

but black was agasint the wall . . . if he is not surley its impossible?

[GreenCastleBlock]

It's always possible

[Jessekein]

You 're expecting a lot of checks from a pinned knight.

[GreenCastleBlock]

confusing comment

[MrPropapanda]

@GreenCastleBlock You always say the computer will check you with his knight, but your queen is pinning the knight. how can the knight even move to check?

[scotland7yard]

brilliant video!

i was wondering, has black got a threat of fooling you onto stalemate if you're not careful at some point?

[pinkyfrogs23]

I like your videos. They are pretty cool!

[rhcbearsfan]

couldnt you play queen b7 at 10:22 is checkmate

[GreenCastleBlock]

No, White was in check.

[dgrakovsky]

very instructive and interesting video. thanks Matt ;-)

[gunplay596]

great video!! thanks. now how about queen vs rook?

[andrewzot]

its hard to see knight patterns. this helps a lot. five stars, thanks

[AsterisKSC]

7:06 why couldn't the knight go to f6? o-o;

[GreenCastleBlock]

..Nf6 Qf7 is mate in 1 (..Kc8 Qc7#, any N move Qd7#). Black, the computer Crafty, will delay mate as long as possible by ditching the knight.

[srn347]

Actually, 1 square from the knight (orthogonally) for the king isn't that bad. The knight has no immediate checks, the king forces the knight to move right away unless guarded (essential in certain positions), and if the knight moves to be 2 orthogonal squares away, the king can either go to the 3 orthogonal square position or repeat the process (forcing either a draw or a retreat of the knight).

[AsterisKSC]

3:40 you could've just played the queen to e5, forking the knight and the king d:

Not really relevant to anything, just pointing it out.

[GreenCastleBlock]

zomg, clicking that link brings me to the time in question. When did they add THAT?

Okay, I was illustrating a concept, not a position from a game, but I had to have kings on the board somewhere.

[AsterisKSC]

I wasn't flaming or criticizing or anything, sorry if I offended you or something. Just pointing something out o-o

[GreenCastleBlock]

That is ok, I was not offended, probably 2-3 more people will "point this out" before all is said and done :-p

[tuberunner101]

Excellent description. You do a fantastic job of clarifying what is happening. I was using the King clumsily, and your explanation of the best squares for the king was tremendously usefull. Thanks for helping me with this!

[familyguy1231]

nice job matt!

[dogma1316]

nicely done once again Matt

[MoonchildMindaugasRo]

Same here :)
