🚀 Deep Green has re-launched! ✨

Seven short years after the previous update, version 2 marks a new era of Deep Green. This is a full rewrite on a modern architecture that can be built upon with even more exciting features in the months and years ahead.

Deep Green is now free. Still with no ads, no tracking, no analytics.

I hope you like it. Enjoy, #chess: https://deepgreen.app

@deepgreen I took Steampunk's queen, the game seems stuck. Opponent doesn't play, neither can I. (Don't judge, I don't play chess well 😄)

@arroz Yes, you hit a bug where the pawn promotion puts the king in check, will be fixed in next release. Thanks for reporting!
@arroz And you found the copy function! :-)
@deepgreen I have no idea what I'm doing, I haven't played chess in ages. 😄 Pawn promotion happens when the pawn gets to the last row, right? Can that happen on my current board?

@arroz You're right, it requires the pawn to reach the opponent rank. It can't take place on your current board. I just saw your last move and assumed the queen was the result of a promotion. Try to copy paste this into a new game (from Wikipedia):

1. d4 d5 2. c4 e5 3. dxe5 d4 4. e3? Bb4+ 5. Bd2 dxe3! 6. Bxb4?? exf2+! 7. Ke2 fxg1=N+!
