@Schniz OK

@MunifTanjim `fnm` has a dedicated `default` function that doesn't require knowing `default` is just an alias. So I think the command to retrieve the default version should not require invoking...

@Schniz you asked me to write a patch, I did so, and it's been sitting for a month.

Looking more closely at schedule, perhaps swapping antichess and zh hourly -- will decrease antichess freq and incr zh freq

Separately, I also think Atomic 5 0 should be made less common, as atomic tends have more forced moves and shorter games
