Big Collection of Chessity.com puzzles (2000+ Puzzles so far WITH SOLUTIONS )


These puzzles were obtained from the tactics site chessity.com, please go to the site and take a look around and get a feel for the puzzles. We believe these puzzles have a high educational value and they were hand made/hand picked by a master chess trainer and that's why we would like to share them with you. Again, please see the website for more details.

If it's white turn to move, then the puzzle will say 1-0, and if it's black's turn to move, it will be 0-1.There are all kinds of puzzles: tactics, all sorts of defensive puzzles, checkmates, quiet moves, and the puzzles range from very easy to very challenging. I think they provide a good range of difficulty and most importantly they seem to be very practical in nature.

Specials Thanks for the team in immortalchess.net for collecting theses precious gems.
