My main questions concern raising preflop and stealing. I think i'm not raising+stealing enough, but don't know which hands to add where. I'm already raising suited and suited 1 gapped connectors in LP. Add offsuited connectors at passiv tables? Or isn't it necessary to raise so many hands at all?

I've taken a stab at 50nl and as you can see... a net loss of -450$ within 3500 hands made me come back down to my 25nl. I'm not complaining, i've played pocket aces, kings and AKo for a loss of 100$ alone.
I'll probably get in another 10K hands at this level and then take a stab again
Til then any comments are welcomed
