4-betting

[bagclip2007]

Well, lately i have been taking a line of NEVER 4 betting preflop. unless i have a short stack thats different. i am talking about 100bb+

my thoughts are that anymore not many ppl pay of a 4 bet like in years past, so when i raise with aa to 4 and get raised to 16 or so i always call because i want them to cbet and make more money, where if they are 3 betting with aqos, they are going to auto muck 2 a 4bet

now for my problem, i read alot of posts that ppl are 4 betting hands like jj 1010 and things, i just always feel like i do it at the wrong times.
Example, i have 4 bet sometimes with qq and been stacked by aa, because by the time i 4bet i feel committed to the pot

do u 4 bet against really laggy players? obv
ever vs tags?
so a 40/30 lag reraises ur button raise, u hold 1010 u 4 bet, do u have to call the shove since uve committed 50bbs or so? or do u just let it go?

also, i play 100nl if that changes
