TheMe was using a civengine, btw
you see kids, when i was your age, we didn't have this newfangled maasheen learning ai. we had to cheat the old fashioned way, and we *liked* it!
Ben claims if he played Magnus 50 times he might win 2 & lose 48. But in reality he would lose 50 of 50, if he played him 500 games he'd lose 500. The gap between Ben & Magnus is wider than the gap between myself & Ben.
should depend on the format. in faster time formats of online games, it might be reasonable to expect ben to hit ~4% winrate vs magnus for example. also note that even with a several hundred elo difference, there is still non-zero estimated winrate by elo.
i haven't played people massively above my chess rating, but i did beat a semi-pro in warcraft 3 back in the day. in normal games he'd massacre me and i had a terrible record against him, but i managed wins twice. the most memorable one was going kotg + hunt and correctly guessing creep route to all-in his army early (it was an unusual route to avoid this too haha), then immediately pressuring base so he couldn't macro out of it and the difference in micro capability was minimized (not many units on either side, and I had more). trash win, but it was a win vs someone who really would be likely to go on 20-50+ game wins streaks vs me in normal conditions. (fwiw, the other win was a tower rush before we knew each other well, which never worked vs him again lol).
i believe ben could pull something off similarly in blitz. magnus makes way fewer mistakes on average in fast time controls, in fact he and hikaru are some of the best in the world at it. but they do make mistakes, so if you spam games there will inevitably come a point where ben gets something in his ~top 5% of games and they make their bad blunder and lose. we don't observe this much in reality, as noted earlier many super gms avoid rated games generally because weaker players have a non-trivial likelihood to draw them and lower their rating points as a result of the draw. in fact, pressure against draw could make super gms press in what are otherwise very draw-like positions, making objectively worse moves to complicate/fish for opponent mistakes and losing as a result if their lower-rated opponent doesn't make them.
As long as the hardware is controlled by the potential cheater I am not sure there is anything you can do. Webcams and microphones can be spoofed, I do not know how the "click off window" works but I would be surprised it could not be got round with some form of virtualization.
the main way they catch cheaters that go to this extent is if the moves are matching engines too frequently. though most cheaters are far less subtle than hans, so it's super obvious. it's not known to what extent people who are more cautious with cheating are caught, hopefully a large % still.
Eventually, a book cheater will memorise his cheats and.. stop being a cheater?
technically true, if he can memorize to that extent...not everybody can do it, and this would allow people without the ability to access the same capability without the combination of talent (for memory) and work (doing the memorization) required. it's an interesting grey area, but imo would typically be considered "cheating" in standard formats until such time as the moves can be called from memory.
There’s vast endgame field, which becomes important the higher you go up the rating ladder. And a vast potential for middle game tactics.
yeah, as i mentioned in the post i talked about it, the advantage gets completely nullified vs skilled players.
I remember watching GM Sjugirov’s stream. So, someone shoots a question, in the stream chat: “which openings do you prefer?”. He immediately shoots back: “good ones”. I feel that’s more than just a joke when it comes to GM chess.
there are a good number of possible openings that do not confer opponent an advantage >1 point of material per engine and are comparable enough that even top engines haven't yet fully "solved" them. i presume this is what gms would call "good openings", with choices that start handing winning chances to the opponent being increasingly bad.
I doubt book cheating alone will take one much higher than 1300.
It really depends on their other skill sets.
yeah, as i think about it this will depend on two things:
- how good is the hypothetical book cheater at replicating book moves, right now?
- how good is the book cheater at other aspects of the game
for someone who is reasonably good at tactics but has limited book knowledge, i would expect a much bigger jump in rating than the opposite...aka a player who already has 5-10 book move knowledge of a couple openings and tends to lose to deficiencies in tactics already.
either way though, if you wind up +3 or better out of the opening because opponent made a mistake in book sequence, the opponent must then play significantly better (or you blunder) to compensate. otherwise book cheater can (relatively brainlessly) trade down into an endgame while retaining a big advantage and win more often on average than otherwise.
Opening theory irrelevant, pawn structure irrelevant, endgame technique irrelevant, everything except tactics irrelevant, because if you're under a certain ELO, the thing that makes the biggest difference in whether you win or lose is that you do or do not blunder pieces or blunder mate.
even gms make tactical blunders, including 1 movers! it's just far, far more rare than lower rated players.
my point here is that book theory necessarily involves some tactical threats. thus somebody with less skill can get a material lead by cheating in this way pretty often at low-mid level elo, by letting the book pick up tactical patterns they can't see themselves. i'm also assuming the cheater isn't completely braindead, and has at least some level of tactical knowledge, and it's just behind that of his opponents.
obviously, this won't help the cheater improve much. but if the cheater were trying to improve as a player, cheating wouldn't be the choice anyway. the whole point of cheating in chess is to inflate rating/perform at a level that skill otherwise can't attain.
one thing about tactical puzzles: it tends to be the case that *because* you are presented the puzzle, you know a winning solution is there. in real games, you don't know this (though some alleged forms of cheating are not specific moves, but 1 bit of information conveying something like this). thus tactical puzzles are training pattern recognition. i wonder if that couldn't be organized more efficiently than chess.com does it (like chaining many different looks of the same tactical idea together and and then doing 100s of those).
