For amateur and professional players alike, chess tactics are incredibly important in developing strategies and actually coming to win games; they are not achieved from the very beginning and sometimes it takes a lot of time and practice to perfect the game style. Though many people study chess tactics to improve their games, true mastery only comes when one has to actually face some crisis cases on the game board. The efficiency or the futility of a move is more relevant and obvious when analyzed in retrospection, hence, it is highly important that you always keep an eye on the game quality after you conclude it.
From this point of view, computer software that enable the user to see the weak and strong points of his or her chess tactics are an immense help. For instance, poor chess tactics may give rise to awkward situations when some bad moves that you make end up by blocking your own pieces. One simple example of a frequent chess tactics mistake many players make is that of moving the bishop in front of the pawn during the game opening stage. In the future development of the game you'll have to retreat with the bishop in order to be able to move the pawn freely. Keep in mind that every move needs to have a finality, otherwise it's simply wasted!
We cannot speak of chess tactics without a certain strategy in mind, therefore, every move you take needs to fit in the overall context of a general application or approach. To put it in other words it needs to have a purpose. There are players who try to built their chess tactics on the mistakes the opponent makes; but waiting as long as that is definitely a bad choice. Of course you may speculate and use any breach in the other's defenses for your advantage, but to actually rely on that completely for building your chess tactics, is definitely wrong.
Those who get to learn the secrets of chess, are aware of how important it is to develop all the primary pieces during the game opening. If at the time when you reach the middle of the game, you still have important pieces lying at the back rank, then you're chess tactics are definitely faulty and chances that you win the game are pretty low. If a bishop is kept away from the action, in game economy we could say that you are playing with one piece less than your opponent, and he or she will not hesitate to use that advantage against you.
