My suspicion is that the bot was a fairly standard chess bot, but the difficulties were set based on computation time. As airplane computers got better, it turned into a beast. As a result, if you tried this on older planes, it might have been “easier”

One of my first paid iOS dev jobs was porting a Go game from iPad to iPhone, don't even think the 4 was out yet. It also used computation time based difficulties. By the time I was done writing it, I knew a few tricks I could eke a win out with on 19x19. When the iPhone 5S came out, I tried it on a whim to check the UI scaling etc... the beginner difficulty on a 9x9 board deleted me. It was grabbing something like 64…

One of the minor weird things about iOS development early on was just how fast the transition was from the simulator being dramatically faster than actual devices to the simulator being slower than devices. When I started out you’d get things working nicely in the simulator and then discover it’s an order of magnitude too slow on a phone. Just a few years later and my phone was faster than my laptop until thermal throttling kicked in.

Last time I flew Delta they no longer had this bot, which made me sad. One of my favorite parts of flying was getting absolutely crushed into a tiny cube by the airplane seat's easy chess bot, and then again by the airplane seat itself when the person in front of me reclines their seat.

> when the person in front of me reclines their seat. As a reasonably tall person I have never reclined my seat and will forever consider anyone who does an asshole. The very fact that you can but don’t do something is the precise space where assholeness is defined.

I have never come across this opinion until it seemed to have blown up on the internet in the last few years.

In short: it plays far too well (~2500 ELO.) People think it originally played at a reasonable level and accidentally got more powerful as the seatback computers got more powerful; the same thing happened to the Mac chess app with the release of the M1.

I pointed out exactly the opposite: surely moral action is only possible when one has agency. If an airline needs to force you to be a decent person, then you have no right to claim decency in the first place. People who lean their seats back are assholes. Claiming “but this is permitted!” proves my point. I can’t imagine what a nightmare world it would be if decency were only possible through the exercise of externa…

And yet I'd prefer both myself and the person in front of me lean back. The upright posture is painful for me. Is your preference more valid then mine? The fact that the chairs are configured that way suggests the cultural norm.

Leaning back doesn't help knee room, the person in front leaning back actually reduces it by the seat back leaning against a tall person's knees.

so I guess you pay to choose seats in the last row of the plane...

> I'm only about 2000 on lichess That puts you in the top 7% of players on the site. I have a hard time believing you could get to that rating without knowing that.

They aren't talking about the site, they're talking about their strength (as measured by that site) so it can be compared to the numbers in the article.

Surely you should blame the airlines, rather than the individuals. They cram more people on, giving you less space - but charge the same - and you get mad at other customers, rather than them for cramming you in.

You have the agency to let the person in front of you have a more enjoyable flight without judging them for it.

That is also a decent and unselfish thing to do.

I don't lean back on flights, but I don't consider the person in front of me an asshole for doing it.

Are you talking about agency and not being an asshole, or are you just being selfish about your space?

There's a bug in the Delta Air Lines chess program. After cxd6 en passant, the captured pawn isn't removed [0]. White's bishop is then able to check the black king through the pawn (the pawn that should have been removed) [1]. [0] https://drive.google.com/file/d/1Nyov4F7eWbT8uNoeclPY8uXVG6f... [1] https://drive.google.com/file/d/1eEPBHqE5rpefE9gWflgS_hUwYGS...

I guess it's just a display bug, then? Though it's hard to imagine what kind of bug would lead the game state and the visual representation to get out of sync in that particular way.

My guess is they only remove captured pieces on the moved-to square (maybe relying on an implicit capture by overwriting an array entry). This is probably easier than actually tracking pieces that get captured.

Even though I'm tall it's about the back, not the knees.

Note that 2000 on lichess is probably weaker than 2000 on chess.com (or USCF or FIDE)

I heard it's never intended to be the same since initial rating for Lichess and chess.com respectively is 1500 and 1200. So they should have 300 rating difference on average. Quite fitting with what the other commenter claims actually.

I don’t think it would average out to a 300 elo difference simply based on the starting rating being 300 apart.

If everything else was the same, and people play enough games they will average out to the same elo.

The difference is caused by many factors. People don’t play enough games to sink to their real elo, the player pool is different, and you gain/lose fewer points per game with Lichess’s elo algorithm.
