No moves to Make

Have you ever played a game where it is like a grid lock and you can't move anywhere? Don't you just hate those games, I do because it is hard to get out of it without losing anything. I like to end up losing my pawns (if I had to) since their purpose is to gaurd and and defend the more valuable pieces. I know this is off topic but how many possible moves are there in chess? I believe it is a lot but not infinite because there is only a total of 64 squares and 32 pieces. Do you know how many there actually is? If you do please comment.
