I wonder if they gave the chess bot X seconds of thinking time in an era when computers were slower? The way you set difficulty for turn based game ai is that you limit how far ahead the algorithm searches. If you set the lookahead based on compute time your difficulties will be way out of line if someone upgrades the CPU.

Something similar happened to the macOS chess game, which has always been bundled with OSX/macOS. Once upon a time it was easy to beat in easy mode, which restricted how long it could thing in advance. When Big Sur rolled out around 2020, Apple introduced a bug which disabled the difficulty slider: no matter what it was set to, it was hard or impossible to beat. In macOS Sequoia, the Chess app got updated again, and…

is there some reason to implement it as a time limit instead of iterations or something else deterministic? it being affected by CPU speed or machine load seems obvious.

or whatever makes sense if “iterations” isn’t a thing, I know nothing about chess algorithms

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.

This reminds me of the time I had my laptop open on the tilt-down tray and the very large man in the seat in front just repositioned his girth (not even reclining the seat) but it flexed the seat back enough that my laptop screen was momentarily caught between the tray below and recessed lip above and was almost crushed.

Sometimes the airlines chess app gives you the option to play another passenger, but even after waiting for half an hour I've never been hooked up with another player. Has anyone else been able to?

It only works with passengers on your same flight. In practice, it's good for kids in the same family or school group who are sitting across the aisle from each other. I've used it for some of their other games

Some day we might fly on the same airplane!

It’s simpler. Chess is a search through the space of possible moves, looking for a move that’s estimated to be better than the best move you’ve seen so far.

The search is by depth of further moves, and “better” is a function of heuristics (explicit or learned) on the resulting board positions, because most of the time you can’t be sure a move will inevitably result in a win or a loss.

So any particular move evaluation might take more or less time before the algorithm gives up on it—or chooses it as the new winner. To throw a consistent amount of compute at each move, the simple thing to do is give the engine consistent amounts of time per move.

How about a nice trip on a train?

I don’t have 5 days to travel across the country.

This wouldn’t bother me as much but it’s really like 5-7 days depending on freight use of the lines and they can’t tell you ahead of time what it’s going to be somehow?
