If you've graduated from Smullyan's books then you may be ready for the pro leagues, of which a sample may be found here. Or look here for one of the most impressive problems I've seen.
On a related note, I helped out a bit with designing the 2013 MIT Mystery Hunt, and in particular designed the chess problems for this puzzle. The puzzle as a whole has a single word as an answer, and you need to know checkers and Magic to solve the whole thing, but the two harder chess sub-puzzles are pretty interesting in their own right IMO.
