This shows how to use the pgn4web tool in a blog, using the iframe tag to embed the chess page.
Below is a set of chess tactical puzzles for you to solve. There are more than 900 puzzles, mostly from top players' games (the puzzle collection is from the scid project). The next puzzle button selects a random new challenge. The show solution button displays and navigates through the solution's main line.
Have fun using pgn4web in your blog!
