Featured is game 94 between Leela Chess Zero and Torch from Chess.com’s Computer Chess Championship 21. The opening is a Modern Defense, in which LCZero gains space on the queenside and secures the bishop pair. A pivotal strategic moment unfolds on the queenside when Torch plays 28…a5. Leela’s response keeps both sides of the board in contention. What follows is a rook trap remarkably similar to the one in a previous game where Leela trapped Stockfish’s rook in the same event. The formula to convert remains the same: identifying a convenient setup to maintain the trap and then open the opposite wing.

The control of blacks rook was tyrannical, never giving so much as an inch of possibility to free it without sacrificing the rest of blacks position, just brutal.

@@MislavIvkovic-sx8vdwe have engines to study lines and moves being played for us is a lot easier to understand than finding those moves and confirming they're good. Even if we don't understand the full breadth of the moves played a general statement like this isn't untrue. Some computer moves are basically nonsensical to us. But this game isn't really one of those games where we can't understand the underlying principles.

My favourite part of this game is actually the king walk. Just casually walk over to a2 to hold a3, then casually walk back to e3 to support the f4 break. Chess played at the highest level really can be quite ridiculous.

Rather than having time restrictions. Engine games should have move restrictions. Like finish the game in unter 50 or 100 moves. Than we would probably see more humanlike play.

@olavbakke2889 11 месяцев назад

It's kinda like a rook sandwich.

@olavbakke2889 11 месяцев назад

I have gotten my rook trapped like that before in online games. I feel just as stupid every time. Crazy that top engines don't understand that it isn't positionally sound. Any 1800 could tell you that and be right about it. If you can't calculate all the way until the rook is freed, it's just a blunder. That's the only sensible approach to having your rook in a pawn sandwich.

@alksjdlkasjdlkajsld9189 11 месяцев назад

The engine's response to your "logic": Beep boop

@olavbakke2889 11 месяцев назад

@@alksjdlkasjdlkajsld9189 I mean, Leela gets it. Gives a huge negative score when the rook is sandwiched in the end position of the line that's evaluated. Stockfish and Torch don't. I'm a hobby chess programmer. I know how these engine's work more or less. My engines would never be able to recognize and penalize something like this either. It's an edge case as far as I'm concerned, not all that relevant to bother with. For top engines, you'd think they managed something so "basic". Leela's eval function takes a lot more computing power which is why it's more positionally sound. At the cost of raw calculation skill ofc.

@alksjdlkasjdlkajsld9189 11 месяцев назад

Whoa that's crazy and pretty cool. So Leela basically made the correct decision when other engines, even Stockfish, got it wrong. That's pretty cool

@olavbakke2889 11 месяцев назад

@@alksjdlkasjdlkajsld9189 Yes, take the position after 37. Ka2 at 10:20 Stockfish 14 thinks black is slightly better, but probably a draw after 37. Nxb5 and letting it's rook get trapped. It thinks it's the only way to get an advantage. Stockfish 16 thinks white has a slight edge, but it also plays 37. Nxb5 at 38 depth which is deeper than this format allows I think. Didn't bother to run it longer. It thinks it's likely a draw. LCZero 0.30 thinks white is significantly better, plus over minus. Obviously it refuses to take the knight. If you play 37. Nxb5, Leela thinks it's winning for white.

@joshburk1897 11 месяцев назад

@preparedsurvivalist2245 11 месяцев назад

I like how at the end there Leela doesn't bother with blockading the passed pawns and making the king run around to defend or escape potential checks. White just sacs its queen for a pawn to expedite the removal of material from the board so it can simplify the position and proceed to an even quicker winning endgame.

@brandont9119 10 месяцев назад

very interesting game

@saudude2174 11 месяцев назад

Leela's king's placement on f4 was very satisfying to watch. It's not often we see queens and rooks on the board being this powerless. Most people would definitely blunder into a draw in that chaotic endgame though. Maybe titled players could figure it out in classical time and still come out victorious. I wonder if you could win that endgame the way Leela did, given enough time Jerry :D

Like a French, often closed. Engines usually play poorly in closed positions.

@testthewest123 11 месяцев назад

Wonder why at 15:01 black doesn't sacrifice a pawn to free the rook? Qe5 forces a queen trade and sacs the pawn on d6, which should set the rook free.

@likesgymnastics5767 11 месяцев назад

i am very weak but i think after the queen trade, king captures pawn and the trapped rook still has no free square to go, since all squares on the row are covered by pawns, bishop and the king. in other words after black sacrifices the pawn to the white king, black is 1 move away from losing his rook

@agar0285 11 месяцев назад

Ra8 Rb7 Qe5+ Qxe5 dxe5+ Kxe5 Re8+ Kf4 Rd6 a5 and even tho the rook is free those passed pawns on the queenside are lethal as the rooks are behind them and the pawns are advanced.

@agar0285 11 месяцев назад

In that position, white is also up a pawn, the black knight is useless and the rooks can't activate due to the excellent placement of the white bishop.

@testthewest123 11 месяцев назад

@@agar0285 a8 Rb7 Qe5+ Qxe5 dxe5+ Kxe5 After that I was thinking: f6+ and then either the king retreats or g5xf6 and Rb6xf6 freeing the rook and being down a pawn. But I am sure I am overlooking something else - the engines definitly see it all. So I wonder what they see that is so much worse than losing a whole rook down the line.

@cftpafan 11 месяцев назад

@@testthewest123 your line makes a lot of sense but I assume it was easier for the engines to calculate to the end of the game after something like rxf6 d6 and the pawns on the queen side and center race down the board quite quickly

@uniktbrukernavn 11 месяцев назад

Very interesting game with the trap. I'm also starting to notice that computers rarely have sexy mates, they kinda play on like there's 500 theoretical moves left and then they run out of pieces. It's like their rating drops to 700 and they don't know how to mate.

@bobthebuilderhecanbuildit 11 месяцев назад

theres something called overfitting in machine learning.. which means if you train too much you become worse at predicting new data. not sure if it applies to this type of ML. If it doesnt, then there is a law of diminishing returns, so it wouldnt get much better

@Jartran72 7 месяцев назад

Alpha zero war not special, there is no reason to believe it would out compete any modern engines. It was just the first time a neural engine was used to let machines learn about what is good for chess positions """instinctively""". It was the first time engines tried to win by using and restrictitng the enemies space and piece mobility in ways that exceeds human capability. Stockfish already was beating A0 the last times it competed and tthere is not reason to believe it would get close to todays engine.
