Daily Puzzle?

Sometimes puzzles are confusing, but these days they're checked with engines, so it's very rare that a puzzle with a bad solution is posted.

It's common for new-ish players to question puzzle solutions, and believe they've found better moves. Well, experienced players certainly do this too, but experienced players realize the next step if asking an engine (or friend) to show them why their move is wrong, and the puzzle's solution is right.

For example

Back in the stone age lent a tactics book to a new player at a club.

He returned it a week later saying he didn't like it at all... he kept finding alternate solutions, and sometimes the solutions in the back of the book were wrong.
