One of the easiest ways to to get Checkmate (a.k.a. ‘Mate’) is when you have plenty of pawns, but opponent has only the king. You might want to get a Knight (as a possible sacrifice) and two queens (to cash in on the possible sacrifice). To make this work you need to be willing to sacrifice a piece, and know when and how to sacrifice. For now you need to do the rest on you’re own, but I have one last piece of advice for you: knights cause PLENTY of destruction.
