You may saw these when you play with your small kids or whoever just started playing chess. Or you yourself may have experiences 'em all.
If one may have analyzed own games or follow the basics of opening, he or she may successfully achieved the middle game with better hopes. Unlike if you like to play an odd opening like Clyde Nakamura's favourites.
Garry Kasparov used to say that the opening moves are normally 10-15 moves. So ideally, soon after 10-15 of your moves, you should 'hold-on' a minute & analyze your pieces & board (space)! Ask yourself-have you achieve the position you want? If you practice & less blunder - i'm sure you'll greatly improve & win more games too.
