Capture the Queen

I use the Game Review feature to create puzzles. But, I pay a Diamond subscription to access that feature and use it to create puzzles. If you don't have access to Game Review, then it may be difficult to create a puzzle. BTW, others have asked the same question many times before. Search how to create puzzles in the Puzzles and General discussion forums. You should find plenty of useful tips.

Yes, you need to use Analysis to load a game which you'll modify to create the puzzle. First, learn what a PGN is and what a FEN is. A PGN is the entire game. A FEN is the string that describes just one position in the entire game. So the FEN string changes every time a move is made.

Congratulations You worked it out.

Chess.com does not currently support posting or sharing self-created puzzles directly to your profile page as a standalone item. You can create and share puzzles by embedding them in forum posts or blog posts, or share the puzzle's URL or PGN in messages or other posts, but there is no feature to showcase your own puzzles on your personal profile page.Your profile mainly shows puzzle ratings and solved puzzle statistics, but not individual user-created puzzles themselves. The sharing and posting of custom puzzles is limited to forums, blogs, or message posts, not the profile section.

That link works.

If Black wins the game, then the puzzle must start with a Black move. The PGN must start with a Black move and the FEN shows a "b" in the string instead of a "w".

Example:

[Event "?"]
[Site "?"]
[Date "????.??.??"]
[Round "?"]
[White "?"]
[Black "?"]
[Result "0-1"]
[SetUp "1"]
[FEN "rn2r1k1/p1p1bppp/bp6/4p3/P2PP1QP/6P1/1pqR1PB1/4K1NR b K - 0 1"]

1... b1=Q+ 2. Qd1 Qcxd1+ 3. Rxd1 Bb4# 0-1

1. Put the PGN in Notepad to edit the text,
2. Delete the earlier moves.
3. Use Chess.com's Analysis tool to find the position that you want to start the puzzle before the first move.
4. Go into Share to see the new FEN for that position.
5. Copy that FEN and paste it into the Notepad inside the square brackets and inside the quotation marks.
6. Copy-Paste the new PGN back into a new Analysis window and click Add Games to load it.

Any text editor on your device will do. I use Notepad on my device.

İts not hard

Wow

Nice

Longer version: Black's second move is different.

It's hard
