how to post chess games (and puzzles)

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:



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

For example, adding this to your post

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



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.

I don't like it, that eval and depth get lost from the PGN if you post a game like that.
Do people really look at games on the webpage itself? I'd rather copy-paste it into my chess GUI of choice.

Aha, okay, I will restore it
