…is there actually a known number of possible chess games to play?? (assuming modern rules that mandate a draw in certain conditions, etc.)
@onethousandtwentyfour Technically it's infinite, because even with the mandatory draw rule there are still infinite loops you can get into, just multi-step ones.
If you rule out loops, though, there's only a finite number of states and so only a finite number of non-repeating sequences of states, so... I'm pretty sure that wouldn't be TOO hard to compute if you were willing to put like a few months into it...
@gaditb i thought a loop was a draw condition?
there are a finite number of pieces and a finite number of spaces on the board so i assumed the fivefold repetition rule would end every game eventually
(i am not a chess expert)
@onethousandtwentyfour I thought it was just a move-response-undo-undo loop, and not anything more complicated?
Like, it would be hard to enforce, if it was, say, move-response-response-response-response-response-undo-undo-undo-undo-undo-undo, just on a counting level.
(But I also could be wrong.)
@gaditb this is the specific rule i am referencing https://en.wikipedia.org/wiki/Threefold_repetition (the draw only becomes mandatory after five times)
@onethousandtwentyfour Oh, no, I guess you're right.
Okay so it's definitely FINITE.,
