Jager, I am the same. Once players won't fold to my strength, I try too hard, upping my raises, slipping in check raises and river raises which have the effect of bloating my TPGK etc. pots unnecessarily. It seems to work better if I actually tighten up a lot, keeping my eye out for opportunities to enter pots with proven bad players, and doing some positional limping if the table is loose passive. But it's hard to change mentality when the overriding feeling is "I'm better than these fuckers"
