yeah many are easy for most top engines, but that's another thing for human being ... and they are meant to be fun (not always hard !)
Most of those positions comes or are derived from my own bullet games on lichess and of course I missed a lot of them, often winning the game with longer variations.

From the Rebel GM challenge : http://www.rebel.nl/gm.htm
The GM Michael Rohde played 26...Qd3?
What is the fastest mate here : Re8 or h6 ?

Crystal 2.0 likes h6 and then g6. The g6 score might actually be M17
