Variant Suggestion: Progressive Chess

+1, and this text is too short, so may your suggestion have my wordly upvote.

Another variant suggestion! This one is epic: en.wikipedia.org/wiki/Double_Chess

Woah, Never seen Double Chess. Looks intense.

Good luck getting this to show on mobile phones! The pieces will be microscopic.

I would definitely be up to play online Double Chess.

Keep the variants coming!

Progressive Chess is one of my favorites, along with Alice Chess. en.wikipedia.org/wiki/Alice_chess
