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

Here is a puzzle based off one of my real games

See if you can find the winning move for white. This puzzle is from a game I played on Chess.com with @pmsummers

(hopefully this works)

here's a puzzle I created heavily based on a game I played. For the position to be possible in a game, assume Nc2d4 was just played, in response to Rf6c6 (using incorrect notation to show where the pieces were).

is this puzzle good?

It has 4 brilliant moves, first its Ra8, sacrificing the rook, because if queen takes then Bf3+, skewering the king to the queen. So black has 2 moves that they can do here, Qh7 or Qa2, if Qh7, then Bg6, sacrificing the bishop and the queen can't take cus else, another skewer (but with the rook) Queen can't go back cus of the rook and black loses the queen. If Qa2, then we have Rxa4, because if you take, you lose the queen with Be8+ and you win the queen, now the queen MUST move back to g8, after Ra8 (again) Qh7 is forced to not lose the queen, and Bg6, finishes off black. But let's say after the first sacrifice of the rook (Ra8) why can't the queen go to f7, e6, d5, c4 or b3? If Qf7, you just take the queen, if Qe6, you have Ra6+ winning the queen through a skewer, if Qd5, then we have Bf3 with the Queen pinned to the King, Qc4 loses to Rc8+ and you win the queen through a skewer, Qb3 loses after cxb3, then you have only Qa2 and Qh7 (which we saw earlier). Thank you.
