This is another great position. White to move.
There's a lingering threat of Ne7, forking the king and winning the rook. However the black knight is protecting that square.
You could just play c4 Rxc4 Re8 ~Kf7 and Nd6 securing the rook advantage.
However, it's not the coolest, therefore my opponent would probably outplay me in the endgame, or I would just win a bad game and get bad reputation.
That's why in this position the best move is Re3. Take a while to think about this move.
My opponent, as he calculated the full variation, blew up like stockfish. He unreasonably played Kf7, clearly allowing himself to be rook down afer Nd6. But then played Kg6, which was a blunder, as after Rg3 Kh6 Nf7 is mate.
Please note that after Re3 Nxe3 is losing for black. I'm not sure how, but my opponent calculated it for me, which is enough.
Note: I'm subscribing to the neoromantic style of chess. If you are some weird kind of philister, the best move is obviously just c4, as pure calculation suggests.
