I think I made an alternate version that speed up the time and opened a handful of browser tabs to watch the games. Most of them do end up in insufficient piece draws or the 50-move rule.

I also made an alternate version which runs faster, and I added some code to count games. About an hour on Chrome got me to this point:

    44 white wins.
    415 ties.
    41 black wins.
    500 games played.

EDIT: Another hour, and the stats are now:

    74 white wins.
    847 ties.
    79 black wins.
    1000 games played.

4 hours later, how does it look now?

I would expect that white/black position would be very similar in results (for random games only, of course).

I stopped it running after 2 hours.
