You are not alone. I did a quick a search for a White Queen moving to c7
being taken by Black Knight on d5. And just that one manouver threw up
100's of examples usually followed by immediatte resignation.
Two will suffice. It's root is just seeing your threats.
Hyde Park - Sicilian Smaug RHP 2005
White is not looking to good here, he needs a blunder to get back into the game.
Instead off he goes to threaten mate on f7 and the Rook on d8. 18.Qc7 Nxc7
lubrio - kasparr RHP 2005
The White Queen is attacked so chop the Knight.
Alas White spots two undefended pieces on b7 and d7. 20.Qc7 Nxc7
When it's your move turn the board around then the backward Knight moves
will be forward Knight moves and you will see them.
Remember with the board turned around all of his pawns will now appear
to be passed pawns so don't panic.
