Why can't I move my knight to take the queen??

Because the knight is pinned against your king. (If you could move it, it would leave your king in check. You can't do that.)

A lot of people including yourself have been quoted as saying that the most dangerous Chess player is The John Bear.
Let’s see.
Um.
Is this a trick question??
No I didnt spot it sorry
I would assume that you had thought that the piece occupying the d1 square was a queen (since the queen would occupy d1 in the starting position).

How can you not see discovering check uuuummm been on the home brew!!?
The OP just joined the site yesterday and might not be familiar with concepts like pin, fork, and discovery.

Hey, DrinkingRevella! As @justbefair said, your king is in a pin. One of the best ways to avoid this type of pin is to get your king castled as quickly as possible. In fact, IMO the best move in the game in your picture is to either cast kingside, and then he (your opponent) will have to move his queen, for your knight can now move; or, you can develop the light-squared bishop on f1 and castle queenside your next turn, for the queenside in your game does have better pawn structure.
