Here is a nice combination from one of my games.  Enjoy!

For more puzzles and tactics, please join my group "Chess Logic".

Of course, you are right!  My bad .  I probably would still play my sequence, though, because I retain the initiative, while white could seize it otherwise .  But 2... Nxe1 is better.  So, I have changed the puzzle to move 5, after white's blunder 5. Rfd1??  Hopefully, it is correct now .

Thank you tonydal!

after nc2f4, the pawn can take the knight, it is a waste of a move.

A knight can never go from c2 to f4...  I believe you mean to d4?  If so, then what you envision is:

Black has a material lead and will soon win.

Beautiful combination and white has no pieces for counter play .

nice puzzle
