Good evening from Greece.. Its with great interest and admiration that I attend all these conversations and tutorials about sudoku strategies, and I think that without all these extraordinary minds (like Myth Jellies, Jeff, Ronk, Havard, Mike Barker and some others) we would never be able to solve the REALLY difficult sudoku puzzles! I have already printed hundreds of pages out of the forum, in order to study them more carefully. At these days I try to learn everything about x-cycles, but I have a problem: although I learned very well (and I also use) the techniques of Alternative Inference Chains (continuous, discontinuous, grouped cycles etc) I stil cant clear what other types of cycles are there, and what is in fact the exact / full meaning of Nice Loops which are their other uses (beyond AICs)? I found the conversations about these strategies in the forum somewhat confusing. May someone of you guys help me distinguish and clearing these things? Thanks in advance.
