DEFENSE

Does extreme defense win the game while playing chess?

Defenses aren't really defensive, because you'll always end up attacking at some point, doesn't matter whether you're under 2000, or above 2000.

but the thing on my mind is to always put the defense in the foreground in a simple simple and simple way so ok this change will be a move you will be

Yes it can! 

In fact, some players like Petrosian or Spassky used to sometimes play "defense" and provoke their opponent into a dubious attack and then they will pounce on it and eventually win by their holding defense

The "real" reason you don't hear this employed as much is because it is MUCH easier to play a good attack than to play a good defense. A good attack has the initiative and the attacker has all the options; however, when defending, you have to play very exact and parry every opponent threat without becoming too passive (or your position will get over-run). Playing a solid "defense" also takes a lot of positional understanding and it is no exaggeration that sometimes 2200 players fail to correctly defense in the manner required!

For this reasoning, even titled players usually advocate to look for chances to attack, have the initiative and have all the play - this isn't the only approach, but it is the much simpler one; why make your life harder on yourself?

p.s. I will add the footnote that sometimes a fairly unequal match-up offers incentive for the higher rated player to play a similar "defense" approach. An example would be like a 2100 player versus an 1800 player. The 2100 player might sometimes just develop solidly and not really do much. They simply keep pieces on the board and maintain the tension to keep the position more complicated. The reasoning is that their lower rated opponent is more likely to slip up first (since they are lower rated) and then they can capitalize on this moment. 

There is a hidden danger in playing this way habitually though; stronger player or not, sometimes you have to play aggressively to net a larger advantage and not looking for ideas like sacrifices or aggressive attacks limits your options voluntarily.
