Complicated Nakhmanson Game Confuses Engines

[@jarirepo1172]

Laughing at the evaluation: Stockfish:"Black is up lots of material!" Leela:"But overally it's nearly equal!". Few moves later, Stockfish:"Oh, black is getting checkmated in few moves..." Leela:"But overally, it's nearly equal!"

[@marekrapavy]

🤣So true

[@tashikrtv6878]

I hope so

[@inszense9848]

Stockfish: What are you doing? You're completely losing. Leela: I'll just play h4 and I'll be fine.

[@illusion6559]

This is the amazing part about chess nowadays. Even though engines can perfectly evaluate 99% of positions, there are still these positions which engines on decent computers can't understand at all. It's such a deep opening that we'd need likely depth 40-50 to analyze this correctly. Other than that it comes down to intuition and maybe a bit of luck to play these positions with correct play.

[@lizardi1037]

I LOVE the nahkmanson cause it's so mysterious. It's so fun to see positions where even engines are puzzled. Most chess positions are completely understood by engines, and that makes the nahkmanson so exciting

[@TheFlux7]

I really liked the video, would love to see more in the future, especially on the Nakhmanson. Thanks for sharing your analysis!

[@JonathanSchrantz]

Glad you liked it! I'll do more if this content in the future.

[@AnandSivaram22]

What if, just what if Nakhmanson is the way chess is solved, that white is definitely winning in depth 100? Jonathan schrantz would be the God of chess, we'll have temples and churches and whatever erected in his name with Jamie as the "guardian God" or whatever to Jonathan's shrine... I merely want to get an honorable plaque in my name on the gates of Schrantz temple...

[@hideehere]

He'll be made a villain/killer of chess

[@simohayha6031]

But that assumes black plays the right opening to even allow a Nakhmanson to be possible. One opening can't solve chess. Black can go caro kann or Berlin or Sicilian whatsoever.

I am a big go fan and player, I saw your video on it a few weeks ago. Because of it I have also watched all your Nakhmanson videos, even though I wouldn't call myself a chess player at all. I am looking forward to seeing more go videos and Nakhmanson videos in the future! :D

[@JonathanSchrantz]

Thanks, Derek! Glad you've been enjoying the channel. I'm very excited about go so there will definitely be some go videos here and there.

[@zenondecitio8539]

Great video! Really interesting the difference between machines. It would be great to show the way you use the engines (which positions, how much time, etc) in your analysis

[@Chris-cs7nv]

Recent stockfish dev version sees it immediately...

[@TymexComputing]

Leela is showing the winning chances instead of points, at least its counting the winning chances not the position+material :) - if all the possible lines are winning for white (a mating option) it will show 128 or 1024 something like that so it is better as it counts the possible players moves that the player might blunder into them :)

[@a.tuannguyen8275]

[@SnoopA5]

would love to see how a gm without prep could handle this in a BO10 or something, wonder if he could get in contact with hikaru or whoever else. Maybe they wouldnt want to get embarassed like that :D

[@Chris-cs7nv]

It also seems to understand the position much better than stockfish 11(or that version of lc0) so you might want to try it but I there should be some lines that it doesn't see the correct moves or it takes a while for it to find it.

[@jtmv8915]

10:34 rook takes e7 would have been sweet. Pinning the queen to the king and the knight to the queen. Also taking with check thwarts bishop discovery on white queen. Edit: turns out it's not that great since it's not winning back enough material. Although chess.com says it's roughly even.

[@DavideMartiniCommentatore]

Maybe, after the black N lands on d6, you can consider g4, threatening mate in one with Qf5...

[@jasongent4088]

Schrantz: Most people would move their knight in this position, I'm sure of it. Me: Yeah, but you're not most people. Schrantz: I think I might be one of those people. Me: Ah, hell. Another brilliant game, Jonathan. Very impressive.

[@josephchiu2403]

You miss taking the knight with rook at 9:56 or is that bad

[@stuartpenwarden253]

Can you set up a custom position of the gambit and play stockfish?

[@matijaslat2100]

do you feel lucky, knight?

[@abdallahguid147]

Plz do a video how to install leela on chessbase

[@wt_wt0]

My brain hurts every time I enter these variations, extremely beautiful!

[@chiwai1986nl]

Black could have played Bishop to D6, so he can play Queen to E7, to provoke white playing Rook to E1. He then doubles up with Rook to E8. I check some scenarios, black should be good.

[@flaydner]

b5 isn’t a question if you don’t take it

13. Be5+ wins one of the pieces back after 13. ... Nxe5 14. Qxe5+ Kg6 15. Qxe7 Kh7 but I'd still be a piece down so I'd prefer to keep as many pieces on the board over winning a little material in the short run. Thanks for the great question!
