  Assuming you are Black, you *have* checked your opponent - your Queen on d1 is putting his King on g1 in check (and checkmate).
  
  **Edit**: assuming Rewan Demontay's reading of your question is correct, then there's no stipulation that you have to check your opponent before checkmate. You can see this in well-known short checkmates, e.g. Scholar's mate. 1. e4 e5 2. Bc4 Bc5 3. Qh5 Nf6?? 4. Qx7# is checkmate without checking first.
