I loved the puzzles created by Nikola. I went for most of the top point puzzles and had 52 points from these puzzles. Towards the end I got so engrossed in one of the puzzles that I forgot to even submit my solutions :)

That explains one of the 0's. Great puzzles with cool logical steps. In each of them I was getting a feeling as though someone was leading me to a solution.
Thanks for the wonderful puzzles.

I had a chance to solve most of the puzzles before the test. In each of the puzzles, the application of Chess Rules was extremely well applied.
Even for easy puzzles (like Hitori, Minesweeper), one has to apply the Chess rules throughout solving.
I also liked that fact that in most puzzles chess rules led the opening, while in some (i.e. Sudoku) I could start with standard sudoku rules, but the chess pieces placement decided final solution.

I am not able to open the puzzle book pdf file with password "chessMess". I wonder where the problem could be...

KrtekHonza: The password is chessMESS. We'll get it corrected on the erroneous page soon.

Corrected.
