Stockfish, like other computer engines, has a feature called "pruning", that eliminates branches in which the player makes very bad moves, this allows a deeper analysis of the best moves.

Curious if we will ever know what Leela's evaluation of the +4.28 position from her point of view. Was it +0.0? In my mind: SCENE: Leela is cornered in the control room by Stockfish and a guard (a bishop). Stockfish: "Surrender, mademoiselle! Your king is exposed and has nowhere to run!" Leela (unperturbed & smiling deviously): "Au contraire, monsieur. If I cannot win, no one will!" (the facility is suddenly rocked with explosions) (sirens blaring) Initiating Stalemate sequence in 5...4... (sirens blaring) Stockfish: "Sacre bleu! How could I not have foreseen this!" [CUT AWAY TO OUTSIDE SHOT of a building exploding with a towering plume of fire and smoke]

Re: AGEthereal's explanation. Makes perfect sense. Though it's interesting because that's a lot like how a human plays, which we typically don't expect from alpha-beta engines. Usually, we expect to see more "human-like" play from neural network engines... Or I guess it used to be that way anyway. But given human's comparatively low calculation speed, we often disregard dumb sacrifices pretty early in too... That said, in this case, they might be forcing enough that a good human player might check them out anyway. Especially if they were specifically looking for a draw... But they aren't THAT forcing... Really interesting

It's a fundamental property of not searching the whole search tree (which would be exponentially expensive), while still playing good chess. Any algorithm, alpha-beta or MCTS or purely neural or whatever, they all need to prune moves (since, again, it would take exponential time otherwise). If these algorithms actually play good chess, they will likely prune moves that any good player (be it machine or human) would prune. You can think of it like convergent evolution. The reason human play still has some special characteristic to it is largely (though not explanatory for everything) because humans are quite bad at chess.

One of the most sophisticated ways of combating this kind of initiative is to quickly find the resign button...and click it aggressively/unrelentingly...until such time that you are fully ready to smash your mouse into the keyboard. It does take time to perfect this technique. So do keep that in mind...lest you might experience some frustration.

Thx Jerry for those hardware specs. I always wondered on what hardware are they running while playing in tcec but was too lazy to look it up. xD Also that explanation of why it had happened is very interesting and totally makes sense. Stockfish might probably be tweaked a bit to calculate such a tactics only in certain cases - particularly when opponent king is in stalemate already as it has no legal moves - but ofc harder to do that than to write it here.

They’ve changed the hardware over the years for obvious reasons. A few years ago they were running consumer level hardware rather than server grade GPU’s. The biggest difference is the capacity of VRAM which heavily influences the model size for the neural network based AI models (bigger model = better performance even at same compute power).

Sometimes, people with casual interest in chess will express confusion and frustration with the rule that a stalemate position results in a draw. They will argue that a side with no legal moves should lose by default. This game is a beautiful refutation of that argument.

The 4090 is a lot stronger than the A100, but the A100 has more memory. Either way if allowed to think longer to equalize, they will produce the same moves.
@benjaminlynch9958
18 сағат бұрын
I suspect for this specific use case the A100 is still going to be faster. AI inference is notoriously a memory bound problem, and the A100 has 50% higher memory bandwidth (in addition to more of it!) due to the use of HMB. The problem with Stockfish with this example is that it considers the first sacrifice or perhaps two, and then prunes that branch as a viable path for the game to take because of the absurd difference in material that arises from it. Only when it Stockfish corners the black king and forcing the line into white piece sacs does Stockfish fully explore that line, and by then it’s too late. This is a problem with the logic inherent with Alpha-Beta tree pruning, and one that can’t be easily solved by simply throwing more compute at the problem. The only obvious way for Stockfish to avoid these situations (and they are admittedly rare) is to fundamentally change the cutoff for tree pruning to more fully explore ‘bad lines’ before discarding them. But that comes at a cost of search depth (and Elo) in the 99.99% of cases where these bad lines really are not playable.

As the post says this is the result of a statistical trade off rather than a direct problem. If stockfish was programmed to be able to calculate lines like this it would lose a lot of strength as most of the time it would be calculating dumb lines. For an engine to be able to see this and retain its strength I believe a ML model like Leela's would be most appropriate in the first place... Hence why Leela exists. Leela and SF have always had their strengths and weaknesses and no one single tool is perfect
@arnoudh6203

Engines check moves in a tree like structure, going through all the branches and evaluating them. To save on computing resources, it stops calculating branches where one side is just throwing away material, this is called pruning. This saves having to look at millions of possibilities that arent worth looking at because they are just random non-sensible moves. I am surprised that the algorithm that checks whether a branch should be pruned did not detect a stalemating possibility here. But you know, it does take 4 piece sacrifices to get there, which is exceptional even for this kind of stalemating situation, which on its own is already exceptional.
