Is this a leak in my texas holdem game?

I never ever 4 bet if the preflop or postflop. Lets say have aa CO in a game 100bb of 1 / 2 in depth. I rise to 7. rascal increases to 24. Even if they are OOP, never bet 4 while not do it just never. First of all im not comfortable with putting 1/4.5 of my stack in preflop. Secondly people can easily put sull'aa on KK, on QQ, or AK. If it is of good c / r me on the fall or float it if no paper in front exits. Then scommetteranno the turn and I will be forced to bend as I know, I know that an overpair or two overcards. Actually, Eric to be blunt it has not helped at all. I 75ss with increases in posiion central or in the best game ina 6handed. I do the same thing with KK. I learned this in second grade. However, what is not know if I should bet 4! I am the first blind bet. An increase in openness is the second bet. A reraise is the third challenge and an increased reraise is the FOUR SCOMMESSI. Thx good for the test anyway and gl with the thing holdem! PS: The rascal is the key. That is why I told you 're OOP:). Eric, really im not sure if I interpreted your words right. Initially, I thought not know what 4 bet and I had thought that steste talking about an increase opened with 75ss. However, I soon rend contoere that you could talk about 4 that scommettete with a gapper suitable. State lifting basically to $ 75 ($ 25 more than half of your stack) with one hand enough position without defective. You said that you were tight as hell, but recently changed your style a little. " It seems like a big difference to me while doing bluff basically half of your stack with 7high. Im 60% sure this is not a good idea, but on the other hand of course this could be very important for the game of goal and could actually be beneficial.
