This is pretty interesting. But the thing is that it always seems that they will call down lighter on the flop/turn just because the pot is small.

I usually hear people saying that you should try bluff the crap out of them, but the thing is that they tend to slowplay pretty often. I do agree with you that we probably only should try attack the small pots and give up on bigger pots. HOWEVER sometimes they will call down 2 barrels and give up on the third. It's pretty hard to say if they're trapping or if they just go for the 2 barrel call and the check/fold river.

Haha, I'm not sure if being more nitty against a nit is the way to go. But hey, maybe it works :)

Yah when they raise out-nit them...

If they have strong preflop ranges they will generally hit high flop textures, so play more passive with thin value and bluffs on those flops.

Figure out where they do most of their folding postflop. It is quite common for more nitty players to fold a lot on the flop, not much on the turn and a lot on the river. Other players fold a lot on flop and turn but very little on the river. There are many more variations as well. Players also adjust to a certain extent to your play and the board textures so don't overdo anything too much.

Also if the have strong preflop ranges and fold a lot to flop cbets, you should not bet many hands for thin value on the turn and river. Polarize more and uses larger bet sizes. You should play this style against all players, but it is even more important against players folds lot on earlier streets.
