I am having lots of trouble dealing with the following players/table dynamics, where I can steal a lot, but often only get called by better.
Consider a table with lots of the following type:
(I find a lot of these players at the current 25NL tables at PP)

VPIP/PFR: 35/5/
Calling raises: 5%

In general, the following is going on:
- There is a lot of limping
- Raising ranges are very small
- Calling ranges are very small

As a result people fold a lot to my preflop raises, so I am stealing a lot. When I do get called I am often behind.
Usually there is not a lot of FE postflop, certainly not after the flop.

My standard raise size is 4BB+1BB per limper and I play 19/14.
I have been raising limpers like it’s my job and in general find myself winning the dead money preflop or loosing quite some medium sized pots postflop, which happens to result in a lot of –EV sessions lately.

Q1. Is it actually most profitable to raise these particular limpers with the following type of hands and why:
- 67s
- A3s
- ATo
- 22
why is it better than limping behind?
If your answer is that there is a lot of dead money, than please consider why 67s is that much better than 84s or Q8o.

Q2. If I have the opportunity to raise A3s or 67s type of hands and steal the blinds often, or limp and get in lots of like 4-way pots and can play fit or fold for big pots. Is limping ever the correct move?

Q3. Should I create a limping/overlimping range at these specific tables? What type of hands should be in that range?
(I can’t get rid of the idea that there is lots of EV in a fit or fold strategy, like 35/10 preflop)

Q4. Lately my thinking about preflop is that it is mostly a way to put ourselfs into profitable postflop situations.
(As we usually raise 4 to win 1,5, I don’t think we primarily do it for the EV)
Is this thinking flawed?
Am I putting myself into profitable postflop situations by raising a lot on these tables?
