why does the engine want me to hang my queen? Can someone please explain


I don't think I understood.
The earlier position was bishop at c4. I moved it to e2. However the engine says I should have moved my knight to e5 capturing black knight. If I did that, wouldn't the bishop at g4 capture my queen?

oh that's amazing. Thankyou
That's not amazing.
This one is cool... I defeated a 1900-rated player in an OTB (over-the-board) tournament because he overlooked the White Queen's check on b5.

wow. that checkmate threat was hard to catch. If I was the opponent I would've thought wow blundered his queen

That pattern... with White moving the "pinned" Knight and sacrificing his Queen for mate... is called a Légal's Mate, named after a French chess player from the mid-1700s..
There are many similar unpinning tactics. That is one reason why Steinitz and Lasker adviced not to pin the KN with the QB.

You mean this?
I think this is called the Sea Cadet Mate

This is a common motif, and it also appears in positions where there is no apparent mate, or gain of material.
It's still far from over, but white has a winning positional advantage.
this line given by pfren is the biggest reason why i played 2 nf3 against the nimzowitch, knowing that it offers black a decent transposition to the normal open games with 2..e5, which is a shame for white, as 2 d4 doesn't allow that and may be objectively stronger also.

What is a shame for playing 2.d4!! which is the recommanded line by the Strongest chess player or Stockfish.

What do you play after 2.d4 d5?
Feel free to consult your allmighty stupid engine.
All three possible lines (3.e5 Bf5, 3.exd5 Qxd5, 3.Nc3 dxe4 4.d5 Nb8!) give Black decent play.
2.d4 is not better , or worse than 2.Nf3, but surely enough a hopeless woodpusher would decorate it with a double exclam.

Pfren's words are pretty harsh, but honestly it's better to think of it like an EGTB... in other words there are many equally good moves. Your goal is to choose a move you understand, or that leads to positions you want.
Engine evaluations fluctuate a few deci-pawns here and there depending not only on depth and hardware, but also change as you put the actual line on the board.
IOW quoting an engine for a single move is pretty meaningless both in the practical sense and in the analytical sense.
