         | 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

       | 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.

         | 
         | 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 supposedly they fixed the
         | difficulty slider, but in the interval silicon improved so much
         | that the old restraints (like think for only a second) mean
         | little. The lowest levels play like a grand master.

             | 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.

       | It's one of those old programs where 95% of the moves are pretty
       | strong. But if you just do nothing and sit back it will
       | occasionally make a random blunder and then you grind it out. I

       | blunders.
