What are some of the things you do online to level your opponents?
Possible examples...
Saying "NH" whenever someone makes a bad call and wins to give them positive reinforcement to do it again?
Posting the blind the first hand you play (esp in EP) to give the impression you're a weaker player?
Starting off as a loose short stacker playing a lag game then either double up or bust, buy in for the max then tighten up knowing the others players won't adjust for several hands.
