I've seen your chess game posts @steemchessboard! This is a really cool implementation! I was considering doing chess on steemit but would have done it slightly differently... yours seems much cleaner than what I had in mind.

To be honest I'm glad somebody beat me to it.

I ended up doing battleships instead... Check it out!
