Puzzles

Once there is a mechanism to have games starting from some FEN possition #290, it could be used for chess puzzles, but would require additional "show solution" button or something similar (have a look at pgn4web solution to this feature).

Already discussed in other issues. See for instance #221 or #239.

I happened to come here with the same question, and seeing that this is not (yet, perhaps) a feature, this is the approach I am probably going to use for now. Perhaps it will help others who end up here!

I am using rpb-chessboard and the bbspoiler plugin. For the puzzle I use two blocks:

The first is the diagram of the puzzle using a fen string such as this used in the example: 5rRk/p1p4p/5n2/4NPR1/1PQ5/P3P2r/5PK1/3q4 b - - 0 1

The second is a shortcode block with the solution which I set to be hidden using the bbspoiler plugin. This block contains something like the following as seen in the current (live test post):
