Nice, GL killing 200NL!

I watch my W$WOSD drop steadily down about as fast as my showdown winnings climb leaving me more or less breaking even over a bunch of hands. I know there's tons of leaks in my game. I know the more straightforward strategy I've followed getting up here needs revising, my play needs to become more dynamic to deal with the new kind of villains 200NL offers.
Something I've found really helped, was keeping an eye out for lines that just dont make sense. Rather than just think "fk it, he's betting/raising he must have me beat", think about what hands he could play that way, and whether he really would play those hands that way rather than another.
