This video is superb! The study itself is magnificent, but all credits to GM Kaidanov who really made a spectacular presentation of it.

the strange thing is, its possible to watch this more than once and still enjoy it, even when you know   whats coming.

This study beautifully shows how surprising and amazing chess can be! And wonderfully told by GM Kaidanov. Very thought provoking. Thank you, GM Kaidanov and Chess.com!

this is the best video i have ever saw! Thanks! -Derrick

sorry  my question regarding beuty and entertainment lesson 4. very nice and exiting studio.whith a lot of phatos.but if the position is winning after the cover of the queen in f6....is winning the same whithout the bishop sacrifice....so the rook sacrifice should be done at the first move...the white mantein the bishop for a more sure final.can change the queen and make a new queen...so 2 knight 1 bishop and one pawn against 1 queen and1 bishop and one pawn near to be promote...seems to me more easy tocontrol the game..........there is something illogical inthe bishop sacrifice.maybe i am wrong .some body can answer to me?

Oh nevermind lol Bf7++ this is really beautiful

Naw greg what about Nb7 on 10:36 white loses

wow beauty and entrtainment, simply amazing, the best non instructive video i have seen

when composing one of these  brilliant studys you really have to be confidant that you have everything covered  or  you could end up looking pretty  silly lol.

After 10 Bb5, Houdini finds a way to prolong the mate for another move, but White gets the satisfaction of capturing another one of those "annoying" knights. 

very nice.....but why not the castle sacrifice at the first move?sorry anyway nice koan

Very interesting and what a great story that follows this study.

Awesome video. In my opinion, though, the bishop still isn't overall better than the knight. The bishop is known to be more useful in open games and this study proves it having a single bishop checkmate a king against 4 knights. But had this been a closed game, the bishop's movement would've been a lot more restricted which gives the knight the advantage. Of course, that is only my respectful opinion and I am nowhere near the level of a grandmaster. 

The best video i ever saw!!!!!!!!!!!!!!!!!!!!!!!
