[@EiQ200]

Never have seen such a brilliant ending.

[@plasmaastronaut]

Uve forgotten engines play 0.1sec per move these days reducing them to around 2500 elo. If SF17 had half a second to think about the position it would have seen this obvious stalemate.

[@EiQ200]

Thought it was a 10min game.

[@andream171]

Really immortal stealmate! 😳🤩

[@simonkotchou9644]

Incredible tactic wow. Ive seen people sac 1 piece for stalemate, but 4 in a row... what a treat

[@blijebij]

Wow The Fish is being played here, I wonder if version 17 is balanced in relation for the progress it made?! Leela lol was genious here!

[@chrisdavis2161]

it is a rapid game after all, stockfish was winning until move 38. Nxb5?? That was a huge blunder. I'm pretty sure time trouble had a lot to do with it

[@blijebij]

@@chrisdavis2161 yes true, as fan of the Fish I realized that to late, its indeed rapid game! Thx :)

[@azharzaman]

If i play against Stockfish : Me:First move... Stockfish : hahha...u are lost, going to get destroyed within 20 moves😄

[@FloydMaxwell]

4 brilliant moves in a row. Not sure I've ever seen that before.

[@soitra]

Interesting...Stockfish intially thinks that 38. Nxb5 is a winning move, but after a while the positive evaluation reduces until it finally selects c7 instead.

[@kamogelomgibe3769]

Incredible

[@mirzahadzic8666]

Stockfish's algorithm probably discarded possibility of 3 pieces sacrifice in a row, so didn't investigate what comes after that. Big mistake, Leela looked also what happens in that branch.

[@gheffz]

It was a fantastic game to cover, great suggestion by your subscriber! Well done to them! I loved it! Incredible incredible amazing escape draw route Leela found!!! Wow! Thanks for you extremely details analysis that went into this coverage, as well!

[@joseraulcapablanca8564]

Again a struggle in a blockaded position for the fish. Brilliant desperadoes from Leela, There is a game from the 1980’s where the English Grandmaster Dr. John Nunn sacrificed several pieces in a row for stalemate. Thanks Josip.

[@michaelmassaro4375]

Wow that was an incredible Self stalemate idea from LC0 I guess Leela must’ve felt Stockfish was closing in with a checkmate with some kind of discovered check and attack with Stockfish Queen on f7 and Bg7 ? Incredible giving up 3 major pieces to gain stalemate maybe it’s good that other engines can compete well vs the fish I guess it remains to be seen if Stockfish will eventually prevail and be the dominant engine overall Thanks Josip

[@mrsommer84]

16:46 "and it's really an incredible and immortal stalemate." Doesn't happen often.

[@torstencuber9114]

My Crystal 5 Engine shows 38.c7! within a few seconds with a clear advantage for White, evaluates the position with + 3! But not on a very strong PC, but on my smartphone!

[@Knigh3001]

This is the best and most interesting game I ever seen. Leela zero is just incredible.

[@remzibayer1387]

The best game of all times

[@coxscorner]

Wow that was crazy.

[@uthoshantm]

The mother of all stalemates

[@skl5532]

this is real chess!! not human mortals plodding along waiting for "mistakes" by other humans who dont have lesions on the brain like they do that

[@youuuuuuuuuuutube]

Crazy thing is that both engines probably saw it was a draw 20 moves ahead.

[@-zelda-]

No, Stockfish missed the stalemate tactic

[@MarcoMate87]

How can you even think this? If Stockfish had seen the stalemate sequence 20 moves ahead, it wouldn't have blundered.

[@Figgy20000]

@@MarcoMate87 Objectively it also thinks c7 is also a draw. It's possible the engine saw both lines as draws but thought this was the best road to victory

[@MarcoMate87]

@@Figgy20000 What? Did you really write in the same sentence that the engine calculated this line as a draw, and then the same engine considered this line as the best road to victory? Do you understand that these two concepts contradict each other?

[@Figgy20000]

@@MarcoMate87 Do you understand that if all roads lead to draw you pick the one that is more likely your opponent will make a mistake? That's literally how Magnus wins so many dead drawn positions that no other GMs can

[@maddumass]

These computer engine games used to be about 100 moves before exchanges were made. What changed?

[@josiahcmiller]

C7 I spotted, which is cool

[@SunPresager]

Like Bobby Fischer said pretty arranged,

pretty sure the engines colluded on this one 😜

How to see this game? Where is the info? i like this.

[@enriquevecerra4651]

Maravillosa tablas.gracias Jozarov.Saludos.

[@torstencuber9114]

Dear Jozarov, some remarks to your analysis: My Crystal 5 engine improves the white game with 20.Nb3! instead of 20.Qg4!?

[@Jozarovschesschannel]

Will check it out thanks

[@soitra]

What sort of depth is Stockfish thinking to in these games please? I did an analysis of this game for move 12, and at depth 41, Stockfish prefered 12. Ba4 (+1.22)

This is a program, so in this case there is no such thing as shape.

[@wiewat231]

It is washed

[@rajesh.x]

on my android lc0 immediately shows pawn c7.but stocksfish goes with n×b5..something wrong with stockfish 17😮

[@Peace_Joy]

OMG!!!! at Nxb5, my sf says its +4.0 evaluation and after RXC6 🔥! by leela it goes upto +8.0 and suddenly drops to +0.0😱!!! Later i analyse carefully, theres other lines for sf to maintain evaluation +3.0, but sf17 played NB5??, and evaluation drops down to +1.0 leading to only line QXf7, but heres too sf17 chooses Bxg7 which comes to 0.0 evalu.! Overall conclusion is that sf17 blunders NXB5 because of Time pressure or sf17 doesnt go into that much depth to see Only one line in Rxc6 leading to draw among the million lines!!!

Hello, thanks for the cover, so with time SF spoted too the stalemate ?? How much time i took him ? By the way, can you cover a game SF won vs lc9 in 29 moves. Game 11 in ccc23 rapid final ?

[@DandoPorsaco-ho1zs]

Even 2200 ELO engines find 41...Bg2+ almost instantly.

[@Figgy20000]

What a foolish comment. They find it instantly because you're checkmated. You have to start giving up material not to lose the game instantly. A human would start throwing away their pieces to try to flag the opponent as well. The actual Brilliancy is Bg7 followed by Rxc6, giving up the F pawn for what looks like a hopeless position, and seeing this stalemate trick far in advance during a rapid event with little time on the clock. Utter insanity, no human would find this in a billion years.

[@aymenmeguenni3276]

💀💀

[@chrisdavis2161]

I analyzed the game on depth 30, backward. According to stockfish, Leela played 3 inaccurate moves: 7... Qxe5?! Stockfish didn't like that move because of 8. Ne2 which seems completely alien 😂 considering that it played c3 in the game to stop Leela from taking the rook in the corner. However, SF was setting a trap for the queen because after Qxe1, Bd4, Qxa2, and Nec3 Queen has nowhere else left to go and has to take out the knight on b1, so actually the best move would have been Qxd4 after it took the rook... This is crazy because the queen got a lot of compensation for itself in that line: 2 pawns, 1 rook, and a knight, but SF says it's completely winning +3.78 eval after that??? Lol. I'm 99% sure that this game came down to time management because SF played All the Right moves. 32. h4! Sealed the deal. SF won 100% of its games from this position. Also I think that the tuning for this 10min+3sec and even on TCEC 30min+3sec is a tad on the weaker side as far as time management.

[@MarlexBlank]

Wow 😂

[@adesuu]

I will try tomorow with sf 17 on my computer and will tell you if mine play differently the game

[@plasmaastronaut]

SF17 appears to weaker than SF16. less surprising leela has slighted ahead.
