Dear retro friends,
Today is the first day of the new Hebrew Year, 5778, a mathematically auspicious number!
In an entirely unrelated matter :D here is a chess position.
Assuming optimal play, how many different possible sequences are there of the next 18.0 moves? (Shorter games don't count. Ignore the rules for drawing by repetition & dead position.)
All the best,
