Why not Nd5?

If ...Nxb3 then Nxe7+ with a fork on the castle and a possible Bxa8 followed by Cxc4.

If ...exd5 then Bxd5 with a threat on a8, and with c8 defending both a8 and c4, you would gain at least the same piece as the solution but with a more advanced position.

The solution doesn't solve the upcoming fork on white's castles.

You can use Stockfish on this site to answer such questions quickly. 1.Nxd5, leaving both Qs en prise, is surprisingly playable and gives W a small advantage, but it's not good compared with the solution 1.Qxc4 because after 1...Rxc4 2.Bxe7 Nb3 3.Rxc4 dxc4, White is a full piece ahead. If 1.Nxd5, Stockfish gives 1...exd5 2.Qxc4 dxc4 3.Bxe7 Nb3 4.Nc3... but not 2.Bxd5? Qg5 which wins the d5-B because the WQ remains under attack.

Haven't used Stockfish previously! Yes I can see now how that plays out. Thanks.
