500 Chess Puzzles, Mate in 3, Intermediate Level: Solve chess problems and improve your tactical chess skills (I'm progressing in Chess)

Pretty fun puzzles. Not all are optimized. Puzzle 499 threw us for a loop for hours... Turns out the puzzle assumes black makes a dumb move instead of putting the white king in check.Either way, neat puzzles that get us thinking.

As described but less than intermediate. More advanced amateur.
