How do you submit puzzles to chess.com?

I wanted to submit a really hard endgame puzzle that occured in my game, but I couldn't find where to submit it

I don't think they take submissions but you can post your puzzle here.

You played those moves in a game?

Well done.

Yes, it's a most instructive endgame puzzle! You could also post it on the "Endgame Study" Forum if you preferred that.

oh no, it was a blitz game and I had like 15 seconds. I played Kg6 making a theoretical draw after Rxg3

Woah. That was a beautiful endgame.

Hmm, but why not pawn takes pawn?

That's a draw. All moves are computer tested and perfect.

The answer depends on what move Black last played, which... can be proven .

Some puzzles using that idea and posted here on the forums do not meet that criteria, but yours does.

Thanks for noticing, KlekleLegacy!

I worked hard to make everything fit rigorously.

I reached this position in one of my games, and its also a pretty good puzzle

(note that my opponent accepted the first sacrifice and i won after hxg6, Qxg6+, Kg8, Qh7#

This happened in one of my games outside of Chess.com and note that black plays queen f6 instead of queen e7
