I've been an 8-10bb/hr winner at 2/5 live for the last 3 years or so. I've recently had to transition to some online play during the pandemic and have been winning at 50-100nl mainly on global poker. I'm trying to move up and have been watching Rob Farha's videos and noticed that he often checks his second pairs and weak top pairs in spots that I would be betting almost always. This seems completely foreign to me as live, these are the spots that I print money going for thin value. Any examples of spots where I could be going for super thin value? Also any other general adjustments I should be making as I approach the mid stakes (200-500nl)?
