Hint: The queen will have to be sacrificed.

isn't this Lasker's Trap or something?

Not sure

This puzzle is ruined by 1... Nxe5. White needs to play 1. h3 first.

No, otherwise it couldn't be checkmate because the opportunity for the bishop to take the queen diverts attention that black could take the knight.

 Ok first off white is way more then just a pawn up his developed is much more advanced and he has all the mometum but this is only if black completly slack off in delevopement. Like he move the bishop to one spot and then move him back and then move him up to the horse. That the only way you can achievement that position.

Just hit solution to the puzzle. It shows why it works. At the sacrifice of the queen, white can get checkmate.

Black can achieve this position without wasting moves retreating any piece. As you may see, the mistake was to make three pawn moves while white was developing:

Why wouldn't black just take the queen?

This is the real thing:

Due to the checkmate threat white made.
