I have been playing against an opponent recently who basically just folds anytime he hasn't hit at least top or 2nd pair or has a big draw. He doesn't call too much OOP pre and is just a basic winning player - he has a good roi although over a small sample size.My question is regarding raising pre - in the first 2 blind levels I'm usually raising 3 or 2.5 times the BB and I'm wondering if I should start raising smaller or even limping more seeing as I don't risk as much money preflop and can take away alot of pots on the flop?My other thought is I should keep raising larger as its gets more money out of him pre when I can take down the flop alot (unless he hits big).I think both lines have their merits but was wondering what you guys thought would be most profitable? - Also taking in account of him adjusting and starting to call a bit more pre (which I have already noticed a little) and 3 betting me lighter preflop.
