A little test of your tactics this time from a mate that came up in an engine game. It was so beautiful and elegant I burst out laughing when I saw it! Spotting little tactics quickly and reliably is the key to successful practical play – the way to improve is to train solving positions like this!
This is from the game Combusken-rofChade TCEC Swiss 2. White to play and mate in 3!

I thought strong engines were programmed to resign when their opponents had this much of an advantage. Amusing position, though.
They let them carry on to mate nowadays (or tablebase win). People complained that they didn’t understand often why the engines had resigned!
