Raise big over limpers with mixed range of strong value (AJ+, KQ, 99+, maybe KJ and AT) and some bluffs (I recommend suited connectors and maybe small pairs). Big means almost twice the total money in the middle. Be aggressive if someone calls post flop since they've capped their range.
Also limp behind (never first in) with medium pairs, and suited Aces. From CO and BN you can also limp behind very marginal hands like 76o or A7o.
The best way I found to adjust is to play more straightforward, value-heavy poker rather than trying to get too fancy. Overall, patience and discipline go a long way in focusing on extracting value, and you’ll see better results over time.
