For those that don't know my story:
I'm trying to adjust my live game so I can make some cash online as well, Live im uber-agro, online I know I have to play a bit more cautious. I'm looking for places where my agression works against me

My question is this: could I make more money here. Is the 4/5 pot bet maybe a bit too scared? There's a few weaker kings he might call 1.50 with here. It would still give drawing hands bad odds, but might make more money. Am I overthinking this?
