NLTRN hypothetical situation

[soop]

You are playing a standard opponent who isn't ubertight and hasn't made any crazy/donkish plays so far. He limps on the button a lot though. You are 15-20 hands in and have equal stacks.

You've raised the last two pots and taken them down uncontested. If this is standard for you lagtards, make it 3 or 4 in a row. Now, opp limps and you look down at KQ or whatever is a borderline raising hand for you OOP. Do you still raise, given you've raised the last few hands?

I typically raise a much smaller range, as I find it difficult to figure out if opp is reraising light or not, but I'm not sure if this is standard.

Second question - what if you are the limper, do you give people more or less credit the third time they raise?
