This forum allows posting of chess games shown as interactive javascript chessboards.

To post a chess game, you need add to your post the chess game in PGN format surrounded by the pgn tags:

how to post chess games (and puzzles) Pgn110

You can add more than one game within the pgn tags.

For example, adding this to your post

how to post chess games (and puzzles) Pgn210

results in this chessboard

[pgn]
[Event ""]
[Site "Paris"]
[Date "1858"]
[Round ""]
[White "Paul Morphy"]
[Black "Duke and Count"]
[Result "1-0"]

1. e4 e5 2. Nf3 d6 3. d4 Bg4 $6 {This is a weak move already.} 4. dxe5 $1 Bxf3
5. Qxf3 dxe5 6. Bc4 Nf6 7. Qb3 Qe7 8. Nc3 c6 9. Bg5 {$23 Black cant develop
the knight because the pawn is hanging, the bishop is blocked because of the
queen.} b5 10. Nxb5 cxb5 11. Bxb5+ Nbd7 12. O-O-O Rd8 13. Rxd7 Rxd7 14. Rd1
Qe6 15. Bxd7+ Nxd7 16. Qb8+ $18 Nxb8 17. Rd8 1-0

[Event ""]
[Site "New York"]
[Date "1857"]
[Round ""]
[White "Louis Paulsen"]
[Black "Paul Morphy"]
[Result "0-1"]

1. e4 e5 2. Nf3 Nc6 3. Nc3 Nf6 4. Bb5 Bc5 5. O-O O-O 6. Nxe5 Re8 7. Nxc6 dxc6
8. Bc4 b5 9. Be2 Nxe4 10. Nxe4 Rxe4 11. Bf3 Re6 12. c3 Qd3 13. b4 Bb6 14. a4
bxa4 15. Qxa4 Bd7 16. Ra2 Rae8 17. Qa6 Qxf3 18. gxf3 Rg6+ 19. Kh1 Bh3 20.
Rd1 Bg2+ 21. Kg1 Bxf3+ 22. Kf1 Bg2+ 23. Kg1 Bh3+ 24. Kh1 Bxf2 25. Qf1 Bxf1
26. Rxf1 Re2 27. Ra1 Rh6 28. d4 Be3 0-1
[/pgn]

Notes and limitations:
- games might include comments and variations
- you can add multiple games for a single chessboard
- for a technical limitation, PGNs exceeding a certain maximum size won't be displayed; the limit is about 4000 chars; if you exceed the limit, the chessboard won't display; try posting fewer games or removing unnecessary comments
- anything you post in-between pgn tags gets converted into a chessboard, even if nested into a code or quote tag
- you can also post chess puzzles (see below)

Example of chess puzzles, add this to your post

how to post chess games (and puzzles) Pgn313

To get this puzzle (click on the question mark to see the solution):

[puzzle]
[SetUp "1"]
[FEN "1r6/p1kb1p1p/3p2p1/PP4P1/1R6/4P1KP/5PB1/8 w - - 3 37"]
37. b6 ab6 38. a6 {White wins} 1-0
[/puzzle]

One more hint for those not familiar with the pgn4web chessboard: if you click square H8 you'll get the help pages.

PS: if you click square E8 you'll get a popup mini-board showing engine analysis of the position; engine is VERY weak, but bear in mind it runs as a javascript app on your browser!

Additional info -

Clicking on squares may give extra information, hint, start clicking on a8, b8 and see what happens.

b8 - showing EPD and FEN.
c8 - showing the PGN
g8 - overview of all the click-square options.
