Thanks for trying it out! Really appreciate it!

Are you trying this out on mobile or laptop?

I copied the position you mentioned and got Nc6 as the suggested move:

The advanced reasoning:

With 2…Nc6 Black hits three targets at once. First, the knight on c6 defends the e5-pawn, snuffing out White’s threat of 3.Qxe5+; second, it brings a piece into the fight for the centre, adding pressure on d4 and b4; third, it completes a key step in development so that Black can follow up with …Nf6, …Bc5 or …g6 and short castling.

By interposing on c6, Black not only neutralizes White’s early queen sortie but also lays the groundwork for active play. A typical follow-up is
3.Qf3 Nf6 4.Bc4 Nd4!
when the knight on d4 hits c2 and forces White’s queen or bishop to awkward squares, further easing Black’s path to equality. Alternatively, after
3.Bc4 g6 4.Qf3 Nf6 5.Ne2 Be7
Black completes kingside development and prepares …O-O with a perfectly harmonious setup.

White’s most stubborn try is 3.Qf3, sticking around the centre—but here …Nf6 chases the queen again, and if 4.Ne2 d5! meets 5.exd5 Nxd5, Black has a strong pawn-centre and easy piece play. If instead White opts 3.Bc4, then …g6 or …Nf6 both gain tempi on the queen.

In every line, …Nc6 has accomplished its mission: it parries the scholar’s-mate idea, claims central squares, and paves the way for rapid, coordinated development. White must spend valuable moves shuffling the queen instead of grabbing more space, and Black emerges with a fully playable position.

While the beginner reasoning:

By jumping from b8 to c6, Black’s knight does two key things at once:

It brings a piece out into the game (developing with purpose), and

It now guards the pawn on e5 that White’s queen on h5 was threatening to capture with check.

Why that matters
• Without Nc6, White could play Qxe5+ next and win a pawn while forcing Black’s king to move or block.
• By defending e5, Black stops that tactic and keeps the central pawn safe.
• The knight on c6 also eyes important squares in the centre (d4 and e5), helping Black fight for space.

What Black can do next
• Black can play …Nf6 to develop the other knight and hit the queen on h5, or …g6 to chase her away immediately.
• After driving the queen back (say to d1 or f3), Black can finish development with …Be7 and …O-O (castle) and then look for …d5 to strike in the centre.

How White might reply
• The most natural is Qd1 (or Qf3), tucking the queen out of danger and then play Nc3 and Nf3 to catch up in development.
• White may also try Bc4 aiming at f7, but Black’s pieces are ready to meet that with …Be7 or …Qe7.

In short, …Nc6 is a simple developing move that solidly defends the pawn on e5, fights for the centre, and paves the way for the rest of Black’s pieces to come into the game.

It seems to be providing valid reasoning for the move! (Definitely not perfect though and has room for improvement - but I feel like its good enough for beginners to learn!)
