Thank you for the giveaway! :)

Battle vs. Chess - appid 211050, sold everywhere except US, Mexico, and Canada
Check vs. Mate - appid 211070, sold only in US, Mexico, and Canada.

Functionally the same game, with the same dev/publisher (Targem and TopWare, respectively), the same copyright notice at the bottom of the game page:

so it really shouldn't matter which appid it is. I personally have 211050, and I live in the US. If you own one, you shouldn't need both. I wonder if it's possible to have both? Anyway . . .

All info on appids taken from steamdb.info

And thanks for sharing it. :-)
