what's the handle mean?

Allykind is a play on words of sorts.  Of course, it is a hat's off to A. Alekhine, a great world champion.  And as a riddle, and ally kind might be a cat.  I'm born year of the Tiger and have lots of cats around the house.

And maybe it means "all y(ou) (be) kind", hoping for kindness over rudeness, sarcasm and obnoxious, critical,  condescending, and just plain mean attitudes.

I believe chess is more than a game.  It is a magic vehicle that can reflect much of a person's inner character.  And it has a beauty of it's own as well.  The chess goddess Cassia will reward those whose devotion she appreciates!
