Wow!!! I have been expecting this for a long time!

I'm still running into lots of repeats in the chess puzzles. Probably 9 in 10 puzzles are ones I've seen before
Thanks for the feedback. Its looks like you have done maybe 10% of current chess puzzles, as we add more this should hopefully help remove duplicates chosen.
We have made some updates to puzzles, improving the display and there is now an FAQ page which hopefully answers many of your questions.
